惠普 655 B6M65EA 笔记本测评
Who doesn't like a bargain? And how much can you get for less than 300 Euros (~$386)? HP has the 6xx-series in their portfolio to compete in the bargain-basement segment. The 620, 625 (2009-2010), 630 and 635 (2011-2012) models were the previous HP contenders vying for the low-budget buyer.
The new HP 655 is an update of the 635. The five at the end of the model number indicates the maker of the CPU - in this case AMD. The HP 650 uses the (generally more expensive) Intel CPUs (Pentium B970 or Celeron B820). With prices starting at 335 Euros (~$431), the bargain hunter might wonder: AMD or Intel? Our test system comes equipped with AMDs new E2-1800 APU (2 x 1.70GHz) and a Radeon HD 7340 (IGP). In our review, we will help potential buyers with their decision-making process and pitch the two platforms against each other. We will also take a look at the low-priced offerings from the other manufacturers.
谁不喜欢便宜货吗？你能得到多少低于300欧元（约$386）？ HP的6XX系列在其投资组合竞争中的讨价还价地下室段。 620，625（2009-2010年），630和635（2011-2012）以前的型号分别为HP的竞争者争夺的低预算的买家。
新的HP655是635的更新。 5结束时的型号序号表示的CPU制造商 - 在这种情况下的AMD。 HP 650采用了英特尔CPU（一般都比较昂贵）（B970奔腾或赛扬B820）。随着价格在335欧元（约$431），投机商可能会问：AMD或英特尔？我们的测试系统，配备了AMD的新的E2-1800 APU（2×1.70GHz）和一块Radeon HD7340（IGP）。在我们的审阅，我们将与他们的决策过程，并帮助潜在的买家，对对方场上的两个平台。我们还将看一看从其他制造商在低价位的产品。
Case
The chassis of the HP 655 is made entirely out of plastic. The surfaces are treated differently: some areas are plain and textured (base unit, display frame), others are smooth and painted (palm rest, keyboard frame and display lid). The painted surfaces feel nice and are not prone to fingerprints. We seriously doubt that the palm rest is scratch resistant, as this would require the use of colored plastic during the manufacturing process. We expect the paint to scuff at the edges sooner or later.
The notebook features a slightly wedge-shaped base unit, seems sturdy and quite suitable for daily use. The 15.6-inch laptop weights in at 2.3 kilograms (5.07 pounds) and can't be considered a lightweight. The notebook is sufficiently solid and should hold up during repeated mobile use. We wouldn't recommend applying too much physical force, as neither the chassis nor the lid is torsionally very rigid. The hinges are solid and well-connected to the base unit. They are quite tight, however - we had to use both hands to open the display (up to a maximum of 135 degrees). The lid moves back and forth ever so slightly.
The gaps are sufficiently even, the parts molded cleanly, and everything is put together nicely. The palm rest is well supported and solid - only one area under the number keys flexes slightly.
The display lid is somewhat easy to twist (up to a certain limit) and flexes when pressure is applied in the middle. The hinges are attached securely and allow the display to be opened up to a maximum of 135 degrees, which is sufficient for working with the notebook on the lap.
The battery can be unlocked and removed with one hand. Since the battery doesn't tilt the laptop and doesn't feature rubber feet, it's possible to operate the HP 655 on a desk without the battery inserted. The rubber pads on the bottom of the laptop are both large and soft and don't allow the laptop to wobble or slide around. When we applied pressure, we were only able to deform the bottom of the laptop in the area of the DVD optical drive and under the fan vent.
There are two covers on the underside that allow the user to upgrade the notebook. In order to remove the covers, the battery has to be taken out (screws are now visible) and one screw for each cover needs to be removed. The following items can be replaced/upgraded: 2.5-inch hard disk drive, RAM (DDR3 SDRAM, one slot open), CMOS battery, and WLAN module (Mini PCI-Express Half Size).
HP 655的底盘完全是由塑料的。表面的处理方式不同：某些地区是平原和粗糙的（基本单元，显示帧），其他都是光滑，涂（掌托，键盘边框和显示屏盖）。油漆表面感觉不错，不容易出现指纹。我们严重怀疑，掌托防刮，因为这需要在生产过程中使用的彩色塑料。我们预计，油漆磨损迟早的边缘。
笔记本电脑具有略呈楔形，似乎坚固，很适合日常使用的基本单元。 15.6英寸笔记本重量为2.3公斤（5.07磅），不能被认为是一个轻量级的。笔记本电脑是足够坚实，应保持在重复移动使用。我们不建议施加过大的物质力量，因为无论是底盘也没有盖扭转刚性。铰链是固体，以及连接到基本单元。他们是相当紧张的，但是 - 我们不得不用双手打开显示器（最高可达135度）。盖子来回移动非常小。
的差距甚至有足够的干净，成型的零件，放在一起，一切都很好。掌托的大力支持和固体 - 只有一个区域下的数字键弯曲略。
的显示盖是有点容易扭曲（最多到一定限度）和弯曲的，当压力施加在中间。铰链连接妥当，且让显示器打开到最大为135度，这是足够的工作与笔记本电脑放在膝上。
电池可以用一只手解锁并除去。由于电池不倾斜的笔记本电脑，并配有橡胶垫脚，它可以在桌面上运行的HP 655没有插入电池。底部的橡胶垫的笔记本电脑都是大而软的，不要让笔记本电脑的摇晃或左右滑动。当我们施加压力，我们只能够在该地区的DVD光盘驱动器的笔记本电脑的底部和变形的风扇出风口下。
有两个盖的底部上，允许用户升级笔记本。为了卸下外盖，使电池具有被取出（螺丝现在是可见的），和为每个盖的一个螺丝需要被移除。以下项目可更换/升级：2.5英寸硬盘驱动器，内存（DDR3 SDRAM，1插槽处于打开状态），CMOS电池和WLAN模块（迷你PCI-Express半尺寸）。
Connectivity
Most of the ports are located on the left side of the chassis near the vent. Available are an Ethernet port, a VGA/HDMI port for an external display, and one USB 2.0 port. An ExpressCard34 slot (standard equipment on the 620/625) is not available any longer. Considering the price, the HDMI port should not be taken for granted. After all - the low-cost Acer Aspire 5250 doesn't have one. The card reader can handle SD, SDHC, and MCC cards. An inserted card only protrudes a couple of millimeters, so there is little chance of breakage. HP doesn't ship a plastic-dummy card (to protect the slot from dust) - not a big deal since those get lost anyway.
There are no ports on the back. If the notebook is used on the table with an external monitor, speakers, and USB devices hooked up, the unwieldy HDMI cable and the long audio connectors get in the way - at the very least, they are an optical nuisance. At least the ports on the right side (2 x USB and the power jack) are located towards the back. The MSI CR360 is a low-cost model which has most ports on the back - a commendable solution.

Communication
Draft N wireless and Gigabit LAN (both modules are sourced from Realtek) are pretty much standard fare nowadays. A Bluetooth module is not available. The webcam has a resolution of 640x480 pixels and features a white status LED. The 0.3 megapixel resolution is the bare minimum current laptops ship with. HP does not offer any webcam-specific software on their website. Software like Skype (video conferencing) or CyberLinks Power Director 8 (for benchmarks, video editing, and rendering) recognized the camera without a problem.
Software
Bargain hunters and those opposed to Windows will be interested in the low-cost version of the HP 655 with SUSE Linux. Even though we also decided on the version with Linux, we didn't actually try it out, since our test procedures are based on Windows. For that reason, we installed Windows 7 Ultimate 64-bit and downloaded all necessary drivers from the HP support website. We were able to find all drivers, but installing each one individually got cumbersome quite quickly. Lenovo allows their customer to create a download packet, which then can be loaded as a bundle.
One advantage of the time intensive procedure: our HP 655 ended up without any bloatware, trial software, and unnecessary tools. Software for creating a system image after the completed install is not available on the support website, so the user has to look elsewhere.
Accessories
HP didn't include a driver DVD. This can be an advantage, as the user is forced to install the latest and greatest drivers. The only other items in the box are a warranty card and a QuickStart guide.
Maintenance
The two covers at the bottom allow access to HDD, WLAN, CMOS battery, and RAM (two slots). Unfortunately the fan system cannot be accessed and cleaned.
Warranty
The standard warranty is a 12-month Pickup and Return Service. The shipping costs are the responsibility of the customer. Care Packs for 3 years of in-home service (next business day) are available for about 160 Euros (~$206). 3 years of Pickup and Return Service are a less expensive option (80 Euros/~$103).
通讯
时下相当多的标准票价的Draft N无线和千兆位LAN（两个模块都来自瑞昱）。一个蓝牙模块不可用。网络摄像头，分辨率为640×480像素，白色的LED状态指示灯的功能。此外，0.3万像素的分辨率是最起码目前的笔记本电脑附带。 HP不提供任何摄像头专用软件，在他们的网站上。软件如Skype（视频会议）或网络联机威力导演8为基准，视频编辑和渲染确认相机没有问题。
软件
逢低买入，相对于Windows感兴趣的低成本版本的SUSE Linux的HP 655。尽管我们还决定使用Linux的版本，我们并没有真正尝试它，因为我们的测试程序是基于Windows的。出于这个原因，我们安装了Windows 7旗舰版64位，并从HP支持网站下载了所有必要的驱动程序。我们能够找到的所有驱动程序，但得到了繁琐的安装每一个单独的相当快。联想允许他们的客户创建一个下载包，然后可以加载一个包。
优势的时间密集的程序：HP 655没有任何的臃肿软件，试用版软件，和不必要的工具。完成安装后创建系统映像软件不提供技术支持网站，因此用户到别处寻找。
饰品
HP不包括驱动程序DVD。这可能是一个优势，因为强制用户安装最新的和最伟大的车手。包装盒中的其他项目的保修卡和快速入门指南。
保养
在底部的两个盖允许访问硬盘，WLAN，CMOS电池，和RAM（两个时隙）。不幸的是，风扇系统不能被访问和清洗。
保
标准保修期是12个月的皮卡和退货服务。运费是由客户承担。 Care Pack的3年上门服务（下一工作日）约160欧元（约$ 206）。 3年的皮卡和返回服务是一个便宜的选择（80欧元/〜$ 103）。
Input Devices
Keyboard
The keys have good travel and clear tactile feedback. The clicking sound is soft and unobtrusive. There is no keyboard flex except a very minor softness in the area around the DVD drive. The reason the typing experience doesn't entirely satisfy: the keys are completely flat (not concave), which makes fluent typing somewhat difficult. In addition, the keys are mounted somewhat loosely, which makes finding the type position difficult when sliding the fingers across the keyboard.
We like the lighted Caps Lock and the WLAN keys. A little LED indicates when Caps Lock is on, which makes it easy to identify.
They keyboard of the HP 655 is fairly large so there was not enough room to incorporate a dedicated number block. The right side of the keyboard is home only to the PgUp, PgDn, Del, Home, and End keys, which are easy to find even when touch-typing. The shape of the keys (which feature a base) has not been modified since the HP 620/625 series. The layout now includes a larger right Shift-key. The HP 630/635 series features the same keyboard as our HP 655.
While the keyboard is a good fit for a "consumer" business user, for a true business laptop both feedback and accuracy would have to be a bit better.
Touchpad
The touchpad is a multi-touch Synaptics V7.7. The surface is slightly recessed and rough (textured). The mouse buttons feature the same surface as the surrounding palm rest. The textured surface of the touchpad gives good feedback and allows for a speedy cursor movement. A vertical scrollbar (not marked) can be activated if so desired; a horizontal bar is not available, since two fingers can be used instead.
PalmCheck can automatically deactivate the pad if the heel of the hand is detected during typing. The touchpad can be turned off via a double-click in a recessed area in the upper left (a little LED lights up when the touchpad is off).
The buttons are pretty loud, have little travel, and require a lot of pressure - exactly the opposite of what a good button design should be like. As far as overall feedback is concerned, the touchpad just can't compare to one installed in a ProBook or EliteBook.
键盘
该键有良好的旅游和清晰的触觉反馈。咔哒声是软的，不显眼。有没有键盘弯曲，但在该地区周围的DVD驱动器中的一个很小的柔软性。究其原因，打字体验不完全满足以下条件：键是完全平坦的（凹），这使得流利打字有点困难。此外，键安装有点松散的，这使得难以找到的类型的位置滑动时，手指在键盘上。
我们喜欢被点燃的Caps Lock和WLAN键。一个小的LED显示Caps Lock键，这使得它很容易识别。
他们的HP 655的键盘是相当大的，因此没有足够的空间，包括一个专用的数字块。在键盘的右侧是家里唯一的PgUp，PgDn键，Del键，主页键和结束键，这是很容易找到，即使触摸打字的。键（设有基地）的形状不被修改后的HP 620/625系列。现在的布局包括一个较大的右Shift键。 HP六百三十五分之六百三系列作为我们的HP 655采用了相同的键盘。
虽然键盘的“消费者”企业用户是一个不错的选择，一个真正的商务笔记本电脑的反馈和准确性将有会好一点。
触摸板
Synaptics的触摸板是多点触控V7.7。表面略有凹陷和粗糙（纹理）。鼠标的按键周围的掌托采用了相同的表面。有纹理的表面的触摸板提供良好的反馈和允许迅速的光标移动。的垂直滚动条（未标记）可以被激活，如果需要的话;一个水平条是不可用的，因为两个手指可以用来代替。
，PalmCheck可以自动停用垫打字时，如果检测到的手的鞋跟。触控板可以通过双击在凹陷区域的左上角（一个小的LED灯亮起时，触摸板处于关闭状态）关闭。
的按钮是相当响亮的，很少有旅游，需要很大的压力 - 有什么好按键的设计应该是完全相反的。远作为整体而言反馈，触摸板不能比较一个在一个的惠普ProBook或EliteBook的安装。
Display
The HD panel (AUO B156XW02 V3) features a resolution of 1366x768 pixels (16:9). It's a non-glare type which should make the business user happy: no reflections! The contrast is extremely low at 118:1 - but this is typical for the price category and simple business laptops. We measured the black point at 1.4 cd/m². The blacks are therefore not truly black; a gray cast is always noticeable. Colors are dull and washed out.
As far as the reference color spaces are concerned, the AUO panel doesn't fare very well. It manages to cover only about half of Adobe RGB. Things look better with sRGB, but are still far from perfect. We do have to note here that we have not seen a laptop in this price range yet that did much better. Not that it really matters - it's mostly the professionals working on workstations that worry about such things.

至于作为参考色彩空间，友达（AUO）面板并没有表现非常好。管理覆盖大约只有一半的Adobe RGB。的事情更好看的sRGB，但还不够完善。我们这里要注意，我们并没有看到一台笔记本电脑，在这个价格范围内，还没有更好的。不，它真的很重要 - 它主要是担心这样的事情的工作站上工作的专业人士。

Brightness Distribution: 90 %

Contrast: 118:1 (Black: 1.4 cd/m²)52.9% AdobeRGB 1998 (Argyll 2.2.0 3D)

51.2% Display P3 (Argyll 2.2.0 3D)
Those tempted to use the HP 655 outside in sunlight won't be very pleased. The 15.6-inch panel is non-glare (as we mentioned before) but the brightness is just too low (below average). 162 cd/m² is not nearly enough - somewhere around 250 cd/m² would be much better. Both in direct and indirect daylight the desktop is too dark - which is very straining and tiring for the eyes.
Inside the brightness is sufficient - as long as the desk is not located directly next to a light-flooded window. Since the display is a LED-backlit LCD, deterioration in quality (like seen with previous technologies) is not to be expected.

The very shallow viewing angles are another strike against the AUO panel. Horizontal angles of more than 40 degrees cause color changes and a decrease in brightness. The same negative changes occur at only 10 degrees for vertical angles. While we would prefer better viewing angles for a business-type notebook, we are aware that this is not something we can expect in this price range.
很浅的可视角度均为友达面板的另一个打击。超过40度的水平角度的颜色变化，导致其亮度降低。同样的负面变化发生在只有10度垂直角度。虽然我们希望更好的观赏角度的商务型笔记本，我们都知道，这是不是我们可以预期在这个价格范围内。
HP equips this 15.6-inch notebook with a dual-core APU from AMD. An APU (Accelerated Processing Unit) is a processor with an integrated graphics card and a single-channel memory controller (up to DDR3-1333). Compared to Intel CPUs with integrated HD Graphics, the Bobcat-cores of the AMD E2-1800 are less powerful. Since the APU consumes little power, netbooks and subnotebooks should see an improvement in battery life, which compensates somewhat for the loss in performance.
The lowliest version of the HP 655 features an E1-1200 APU with 1.4 GHz core frequency and a Radeon HD 7310. Because of the already very low performance scores of our test system and the minor price differences, we can't really recommend this setup. We are going to evaluate the performance of the AMD E2-1800 with the Radeon HD 7340 in our review. Previous tests of other systems featuring the same processor (Lenovo G585-M8325GE and Sony Vaio SVE-1111M1E/P) showed barely any difference to the predecessors E-350 and E-450 (offered since early 2011).
The APU features a TDP of 18 Watts and a frequency of 1.7 GHz (E-450: 1.6 GHz) and doesn't offer Turbo Core. Our test system features 4096 MB DDR3 RAM (1 x 4 GB, 1 x empty SO-DIMM slot). We installed 64-bit Windows 7 Ultimate to conduct our tests, which should be able to extract every last bit of performance out of the 64-bit APU.
HP装备与AMD双核APU这款15.6英寸的笔记本电脑。 APU（加速处理单元）是一个集成的图形卡和一个单通道内存控制器（DDR3-1333）的处理器。集成的高清显卡，山猫核心的AMD与Intel CPU相比E2-1800是那么强大。由于APU功耗很低，笔记本电脑和亚笔记本电脑应该会看到一个改进的电池寿命，这在性能上的损失有所补偿。
最低级版本的HP655采用E1-1200 APU与1.4 GHz的核心频率和一块Radeon HD7310。由于我们的测试系统和微小的价格差异已经非常低的表现评分，我们真的不能推荐此设置。我们将在我们的检讨的AMD E2-1800与Radeon HD7340的性能进行评估。其他系统具有相同的处理器（联想G585 M8325GE和索尼Vaio SVE-1111M1E/ P）以前的测试显示，在前辈E-350和E-450（自2011年年初提供）几乎没有任何区别。
APU拥有一个TDP为18瓦，频率为1.7 GHz（E-450：1.6 GHz的），不提供涡轮增压的核心。我们的测试系统提供DDR3内存4096 MB（1 x 4 GB SO-DIMM插槽，1个空）。我们安装了64位Windows 7旗舰版来进行我们的测试中，这应该是能够提取每一个位的64位APU的性能。
Processor
For our performance test, we compare the E2-1800 (1.7 GHz) to the predecessors AMD E-450 (2 x 1.65 GHz) and E-350 (2 x 1.60 GHz). We are also interested to see how the test unit fares against the current Intel Pentium low-voltage CPUs. Since some of those systems are roughly in the same price bracket (under 400 Euros/~$514), we include them in our comparison.
We use the Cinebench R11.5 64-bit Single- and Multi-Core tests. The E2-1800 managed only 0.66 points in the Multi-Core test. This result is marginally better than the E-450 (example Samsung 305U1A, -3 to -6 %). The E-350 was about 10% slower. A Pentium 987 (also dual-core) is about 71% faster (Acer Aspire One 756, 11.6-inch).
The Single-Core test confirms the results of the Multi-Core test: 0.34 compared to 0.31 points (E-450, -9 %). The Pentium 987 is about 74% faster. The Intel i5-3317U Low-Voltage-CPU (found in many Ultrabooks) offers about 200% more performance. AMDs Pumori platform for subnotebooks (A10-4600M) is 106% faster.
CPU performance doesn't change whether the system is running on battery power or not (we confirmed with the R11.5 Multi test).
对于我们的性能测试中，我们比较了E2-1800（1.7千兆赫）的前身AMD E-450（2×1.5 GHz或1.65 GHz）和E-350（2×1.60千兆赫）。我们也有兴趣来看看测试单元对目前的英特尔奔腾低电压CPU的票价。由于一些系统大约在同一价格档次（在400欧元，/〜514美元），包括他们在我们的对比。
我们使用CINEBENCH R11.564位单核心和多核心的测试。 E2-1800在多核心测试管理仅0.66点。这个结果略好于E-450（例如，三星305U1A，-3到-6％）。 E-350是慢了约10％。一个奔腾987（双核）是（宏碁的Aspire One756的11.6英寸）约71％的速度。
单核心的测试证实的结果，多核测试：0.34至0.31分（E-450，-9％）。奔腾987是快了约74％。英特尔酷睿i5-3317U低电压CPU（在许多Ultrabooks）提供约200％的性能。的AMD的PUMORI平台为亚笔记本电脑（A10-4600M）是106％的速度。
系统是否运行在电池供电（我们确认与R11.5的多测试），CPU的性能没有变化。
System Performance
The CPU tests show that the AMD E2-1800 performs only marginally better than the predecessors E-350 and E-450. How about overall system performance? For these types of tests, hard drive speed, as well as RAM and GPU performance come into play.
The results show fairly low performance, which is in line with other APU systems, the PCMark 7 score is 977 points (965 for the Vaio SVE-1111M1E/P; 982 for the Lenovo G585-M8325GE). The Acer Aspire One 756 with Pentium 987 (HD 2000) offers 49% more performance. A HDD system with Core i5-3317U (Dell Vostro 3360, HD 4000) is about 159 % faster. Only Atom-based netbooks with the N2600 or N2800 score lower (-24 %, Asus Eee PC R052C).
These scores don't favor the APU systems. One redeeming quality could be the hardware acceleration the GPU has to offer. We will evaluate this using the tool Power Director 8 in the section "Graphics Card".
CPU的测试表明，AMD E2-1800的性能仅略好于E-350和E-450的前身。系统的整体性能怎么样呢？对于这些类型的测试，硬盘驱动器的速度，以及RAM和GPU性能的发挥作用。
结果表明相当低的表现，这是在与其他APU系统，在PCMark7的得分为977分（965的Vaio SVE1111M1E/ P;982为联想G585-M8325GE的）。宏碁Aspire One756采用Pentium987（HD 2000）提供49％以上的性能。 A HDD系统采用酷睿i5-3317U（戴尔Vostro成就3360，HD 4000）约159％的速度。只有基于Atom的上网本N2600或N2800得分较低（-24％，华硕Eee PC R052C）。
这些成绩不利于APU系统。一个救赎的质量可能是硬件加速的GPU所提供的。使用该工具的威力导演8“图形卡”一节中，我们将评估这。

Storage Devices
The Hitachi-sourced (HTS547550A9E384) conventional hard disk drive has 500 GB capacity, spins at 5400 RPM, and has a negative impact on overall system performance. While HD Tune shows an acceptable and pretty average sequential read performance of 68 MByte/s, small and dispersed data (4K read) slow the hard drive down significantly (other drives in the same category are up to 100% faster - like Samsung's SpinPoint M7 HM321HI in the Samsung R540). The hard drive activity LED is on the left side of the chassis and barely visible.

另外，也请我们的HDD / SSD比较。
Graphics Card
The Radeon HD 7340 is DirectX-11 capable and offers the highest performance among the IGP graphics units of the AMD E2 series. The Turbo Core frequency is now 523-680 MHz (the HD 6320 in the E-450 had a clock speed of 500-600 MHz). The technical specs, like eighty unified pipelines, UVD3 video decoder (CPU relief) and 40-nm process, remain the same.
If we believe in what the APU philosophy promises, the integrated Radeon HD 7340 should be able to easily surpass Intel's low-voltage graphics options. To find out if that's the case or not, we run our 3D benchmarks, Power Director 8, and test newer and older games.
The result of the 3DMark 06 was 2512 points, which is only about 5% better than the HD 6320 (e.g. Samsung 305U1A). The 11.6-inch Aspire One 756 with Pentium 987 (HD 2000) is only slower by about 9%. The HD Graphics 4000 of the Core i5-3317U (e.g. HP Envy 6-1000sg) easily outperforms both (+200%).
The AMD IGP scored 361 points in the 3DMark 11. That's about 30% faster than the E-350 and and 10% faster than the E-450. We can't include the Intel HD 2000 here since it doesn't support DirectX-11. The HD 4000 in the i5-3317U does though - and is 20% to 80% faster (e.g. Vostro 3360).
DirectX11的Radeon HD7340的，并提供了最高性能的的IGP图形单元的AMD E2系列中。现在的Turbo睿频523-680兆赫（E-450的HD 6320在500-600兆赫的时钟速度）。技术规格，如80统一管道，UVD3视频解码器（CPU救济）和40-nm工艺，保持不变。
如果我们相信APU的理念，承诺什么，集成Radeon HD7340应该能够轻易地超越了英特尔的低电压图形选项。如果是这样的话，或不运行3D测试，威力导演8，和测试新的和旧的游戏。
3DMark 06测试结果为2512分，这是只有约5％，优于HD 6320（例如：三星305U1A）。 11.6英寸的Aspire One756，奔腾987（HD 2000）是只慢了约9％。高清显卡4000的Core i5-3317U（例如，惠普Envy61000sg）轻易地胜过（+200％）。
AMD IGP在3DMark11中拿下361分。这是约30％的速度比E-350和10％的速度比E-450。我们可以不包括英特尔HD 2000在这里，因为它不支持DirectX11。 HD 4000酷睿i5-3317U虽然没有 - 而且是20％至80％的速度（例如Vostro成就3360）。
To check if the Radeon card is capable of hardware acceleration, we use a 1080p video project we created in Power Director 8. The result (compared to the Pentium 987) is quite disappointing: The Intel-based Aspire One 756 only needs about half of the time (8 minutes compared to 16 minutes). AMD's Accelerated Parallel Processing and Intel's effect accelerator were both active for the test.

Gaming Performance
The tests we have conducted so far reveal that the E2-1800 APU with the HD 7340 has a very mediocre gaming performance, not unlike the predecessors E-450 and E-350. The table listing the games tells the story: most entries are red (meaning unplayable). Only older games from 2008 and 2009 run without major lag (as long as details are set to low).
The HD 2000 (Pentium 987) performs a bit slower: Risen (2009) lags by about 17%, Far Cry 2 (2008) only about 2%. The HD 4000 (i5-3317U - frequently found in Ultrabooks) offers much better performance: Risen is about 88% faster.
Compared to the Intel Core low-voltage graphics, the 3D performance of the new APU leaves much to be desired. The HP 655 can't really handle games. We can't confirm that the APU can surpass Intel's HD Graphics, either - on the contrary: the HD 4000 seems to be the best compromise between gaming performance and low power consumption.
测试中，我们进行了迄今为止发现，E2-1800与HD7340有一个非常平庸的游戏性能，而不是像在前辈E-450和E-350 APU。下表列出了游戏的故事讲述：大多数条目是红色的（意思是不能玩的）。只有老游戏，从2008年和2009年没有大的滞后运行（只要细节设置为低）。
HD 2000（奔腾987）执行慢了一点：复活（2009）落后约17％，孤岛惊魂2（2008）只有2％左右。 HD 4000（酷睿i5-3317U - 经常发现Ultrabooks）提供了更好的性能：复活的是约88％的速度。
了英特尔酷睿低电压图形相比，新的APU的3D性能留下许多有待改进。 HP655不能处理的游戏。我们无法确认APU可以超越英特尔HD显卡，无论是 - 相反：似乎是HD 4000的游戏性能和低功耗之间的最佳平衡。

Emissions
The fan system doesn't have huge range as far as the fan speed is concerned. During idle and simple office tasks we measured 33 dB(A). Compared to that, the level of the DVD drive can be considered noisy: 36.8 dB(A). During our stress test, we managed to push the system to a noticeable 38 dB(A). This result didn't change, regardless if we played a game or conducted a synthetic stress test using FurMark (GPU) and Prime95 (CPU).

Temperature
During simple office duties and while surfing the Internet, the average temperature (lots of idle) at the bottom of the laptop is only 31 degrees Celsius (87.8 degrees Fahrenheit). The palm rest remains cool at 29-30 degrees Celsius (84.2-86 degrees Fahrenheit). During load, the picture changes somewhat, although not significantly. The temperature at the bottom of the laptop increases by about four degrees Celsius (7.2 degrees Fahrenheit). The palm rest only reaches 33 degrees Celsius (91.4 degrees Fahrenheit).
The AMD APU does not offer a Turbo Core, so throttling is not an issue. Cinebench R11.5 Multi shows that the E2-1800 maintains 2 x 1.7 GHz. The thermal sensor for the CPU and GPU (one package) indicates a temperature of only 67 degrees Celsius (152.6 degrees Fahrenheit). Intel Core processors reach temperatures of 80-100 degrees Celsius (176-212 degrees Fahrenheit) when under load.
在简单的办公室工作，并在上网冲浪的同时，在底部的笔记本电脑的平均温度（怠速）只有31摄氏度（87.8华氏度）。掌托保持在29-30摄氏度（84.2-86华氏度）的阴凉。在加载过程中，画面改变一些，虽然没有显著。底部的笔记本电脑的温度增加了约4摄氏度（7.2华氏度）。掌托只能达到33摄氏度（91.4华氏度）。
AMD APU不提供涡轮增压的核心，所以，节流是不是一个问题。 CINEBENCH R11.5多E2-1800保持2个1.7 GHz的。热传感器的CPU和GPU（一包）表示摄氏度（152.6华氏度）的温度只有67度。英特尔酷睿处理器温度可达摄氏80-100度（华氏176-212度）时，根据负载。
(+) The maximum temperature on the upper side is 37.5 °C / 100 F, compared to the average of 34.3 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(+) The bottom heats up to a maximum of 38.2 °C / 101 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 29.6 °C / 85 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are reaching skin temperature as a maximum (32.8 °C / 91 F) and are therefore not hot.
(-) The average temperature of the palmrest area of similar devices was 27.6 °C / 81.7 F (-5.2 °C / -9.3 F).
Speakers
The HP 655 has two stereo speakers under the palm rest towards the front of the laptop. The middle range is overemphasized, bass and treble are lacking. The volume level is OK for a 15.6-inch laptop. Distortion doesn't occur even at the highest volume levels. The notebook has an audio jack which allows hooking up external speakers. Alternatively, the HDMI interface can be used to transmit audio to a TV or external TFT with built-in speakers.
HP655的掌托下有两个立体声扬声器，朝前面的笔记本电脑。过分强调中间范围，低音和高音所缺乏的。音量电平是OK的15.6英寸笔记本电脑。失真不会发生，即使在最高音量水平。笔记型电脑有一个音频插孔，可以连接外部扬声器。或者，可以使用HDMI接口来传输音频到电视机或外接TFT与内置扬声器。
Power Consumption
Frugal shoppers are usually also energy conscious and will appreciate low power consumption. Eight to twelve Watts during idle are quite low, especially when we compare these results with the 11.6-inch Aspire One 756: the low-voltage Pentium system needs eight to ten Watts. Intel Ultrabooks with Core i5-3317U usually consume four to twelve Watts, depending on their form factor. The 13.3-inch Toshiba Satellite Z930-119 and the Fujitsu LifeBook UH57 need six to nine Watts and six to ten Watts, respectively. The Asus Zenbook Prime UX31A is a real power miser and needs only four to ten Watts. The 15.6-inch Samsung 900X4C-A04DE consumes seven to twelve Watts.
To determine the maximum power consumption we use Prime95 and FurMark (stress test). We measured 32.5 Watts - which also means that the 65 Watt power adapter is appropriately sized. When only the CPU is tasked (Prime95), the power consumption is 25.4 Watts.
节俭的消费者通常也都是能源的意识和理解低功耗。 8到12瓦时，空闲模式下是相当低的，特别是当我们比较这些结果与采用11.6英寸的Aspire One756：低电压的Pentium系统需要八到十瓦。英特尔Ultrabooks采用酷睿i5-3317U消耗十一时五十六瓦，这取决于它们的形式因素。 13.3英寸的东芝Satellite Z930-119和富士通LifeBook UH57需要六至九个月瓦和6到10瓦。华硕ZENBOOK总理UX31A是一个真正的节省电力，并且需要只有四个10瓦。 15.6英寸的三星900X4C A04DE消耗7到12瓦。
要确定我们使用Prime95和FURMARK（压力测试）的最大功耗。我们测量了32.5瓦 - 这也意味着，65瓦电源适配器是大小合适的。当只有CPU的任务（Prime95的）时，功耗为25.4瓦。

Battery Life
Cheap laptops don't have good battery life. That might have been the case at one point - but even though AMD's APU-based systems don't offer high performance, they come with good to great battery life. That's true even when the laptop in question is in the lowest price bracket.
The HP 655 impresses here and manages 5:22 hours (WLAN surfing, 322 minutes). The run time only decreases significantly under constant load. Interestingly enough, it doesn't matter much if both CPU and GPU are fully utilized or if it's only one component. We ran separate tests using both FurMark (GPU stress test) and Prime95 (CPU stress test). The result: 2:24 and 2:17 hours, respectively. Not really a big difference to the 2:08 hours we saw in the "normal" stress test using Battery Eater Classic.
The maximum battery life (during idle) we established with the Battery Eater Reader’s Test: 6:32 hours. This is not really a relevant test, however, as the brightness is turned down all the way and wireless is turned off.
The laptop was able to play DVD movies for 3:41 hours. Recharging the battery completely for the next session takes 1:56 hours. We included the times of the predecessors HP 630 (P6200, not low voltage) and the APU-equipped HP 635 (E-240) below in parenthesis. We didn't see much of a difference compared to the previous APU system, but the Intel-based notebook posted a WLAN run time that is about 50% shorter (not true for battery life under idle).
便宜的笔记本电脑没有良好的电池寿命。可能的情况下在一个点上 - 但即使AMD的APU为基础的系统不提供高性能，配备好很长的电池寿命。这是真实的，即使在有问题的笔记本电脑中价格最低支架。
令人印象深刻的HP655和管理5点22小时（WLAN上网，322分钟）。恒定负载下的运行时间只下降了显着的。有趣的是，它并不重要，如果CPU和GPU都得到充分利用，或者如果它是唯一的一个组成部分。我们进行了独立的测试，使用这两种的FURMARK（GPU压力测试），Prime95的（CPU压力测试）。结果：2:24和2:17，分别。不是一个真正的大的区别，我们看到在“正常”压力测试使用电池食经典的2:08小时。
最长的电池寿命（在空闲时），我们建立了电池的食阅读器的测试：6:32小时。然而，这是不是一个相关的测试，的亮度是打开了所有的无线功能已关闭。
笔记本电脑能够播放DVD电影为3:41小时。电池充电，为下一届会议1时56小时。我们时代的前辈HP630（P6200，而不是低电压）和APU的HP635（E-240）在下面的括号中。我们没有太大的区别，相比以前的APU系统，但基于英特尔芯片的笔记本电脑发布了无线局域网的运行时间缩短约50％（不正确的
Verdict
Hewlett Packard offers up basic 15.6-inch business laptops with their 6xx-series. The youngest member of the family, the HP 655, continues the tradition: non-glare display, good keyboard layout, low emissions (heat and noise level), and very good battery life. Depending on the configuration (APU version, RAM, hard drive, and OS), said system can be had for a starting price of under 300 Euros (~$386). Our test system (HP 655 B6M65EA) features the AMD E2-1800, a 500 GB HDD, 4 GB RAM, and a Linux operating system.
Unfortunately, the notebook has a few weaknesses that lower its score. The system still managed a "GOOD" (76%) - despite the fact that the rigidity of the chassis has decreased when compared to the HP 620/625. The display is not usable outside in direct sunlight. In this price category, inferior contrast and low viewing angles are part of the game. The dark display is pretty much unreadable when exposed to daylight; non-glare can only do so much.
The HP notebook faces stiff competition in the segment between 300 and 350 Euros (~$386 and $450) (check out "The competition" on the right). We reviewed quite a few of the low-priced alternatives. A test of the Intel-based family member HP 650 will follow shortly.
惠普提供了基本的6XX系列的15.6英寸商务笔记本电脑。最年轻的家庭成员，HP655延续了传统：无眩光显示，良好的键盘布局，低排放量（热量和噪音水平），以及非常良好的电池寿命。根据不同的配置（APU版本，RAM，硬盘驱动器，OS），系统的起拍价在300欧元（约$386）就可以了。我们的测试系统（HP655 B6M65EA）采用AMD E2-1800，500 GB硬盘，4 GB RAM，和Linux操作系统。
不幸的是，笔记本电脑有几个弱点，降低其得分。系统管理的一个“好”（76％） - 尽管事实上，刚性的底盘下降时相比，HP六百二十五分之六百二十○的。显示屏在户外阳光直射的地方无法使用。在这个价格类别中，下的对比度和可视角度低是比赛的一部分。暗显示，几乎是不可读的，当暴露在日光不刺眼只能做这么多。
惠普笔记本电脑面临着激烈的竞争，在300至350欧元（〜$386和$ 450）（“竞争”，在右边）段。我们评论相当一些低价的替代品。基于Intel的家庭成员的HP 650的测试将接踵而至。
