AMD Ryzen 9 7945HX分析--Zen4龙系列比英特尔猛禽湖-HX更快、更高效

AMD拥有最强大的移动CPU。

AMD新的Zen4 CPU终于来了,新的旗舰产品Ryzen 9 7945HX与英特尔的猛禽湖HX型号竞争。新的Zen4核心(Dragon Range)的性能非常好,Ryzen 9也比英特尔的HX CPU更有效率。

我们已经评测了两款首次采用最新的游戏笔记本AMD Ryzen 9 7945HX(Dragon Range),它是基于新的Zen4核心的。是时候让我们将新的AMD芯片与目前英特尔的猛禽湖HX模型进行比较了。HX处理器代表了AMD和英特尔最快的移动处理器,它们的功耗远远超过100瓦特。这意味着它们主要用于15英寸以上的大型笔记本电脑,用于多种使用场景(游戏、工作站、内容创作)。在这篇文章中,我们将仔细研究原始单核和多核性能以及效率。

注意:华硕的两款搭载AMD Ryzen 9 7945HX的评测样品( ROGStrix G17 ROG Zephyrus Duo 16 )在外置屏幕上运行时需要独立的GPU。因此,我们通常的功率测量略微受到GeForce GPU的影响,新的AMD型号的纯CPU效率实际上比我们下面的数字要好一点。

概述:AMD龙系列与英特尔猛禽湖-HX的对比

AMD和英特尔的两款移动处理器的概念是不同的。英特尔在之前的第12代Alder Lake芯片中引入了由性能和效率内核组成的混合架构,而AMD在最新的AMD芯片中仍然只使用成熟的Zen4内核。新的Ryzen 9 7945HX使用16个Zen4核心,这意味着它可以同时执行32个线程。

英特尔从酷睿i9-13900HX开始,将最新猛禽湖模型的效率核心数量增加到16个。它们仍然与8个性能核心(包括超线程)相结合,这意味着它们也可以同时执行多达32个线程。酷睿i9-HX处理器(13900HX、 13950HX,13980HX)只在其最大涡轮增压时钟方面有区别,而13950HX还支持英特尔的vPro技术。

在耗电量方面也有很大的区别。不过,你可以很高兴地忽略制造商在规格表中宣传的TDP值。另一方面,英特尔列出了Core i9-13980HX的典型消耗量为55瓦特,最大消耗量为157瓦特。然而,在我们的评测中,我们已经看到有短暂的时间超过200瓦特。

淘宝网AMD Ryzen 9 7945HX(Dragon Range)是用5纳米工艺制造的,而英特尔仍在使用旧的10纳米工艺(FinFET,英特尔7)。英特尔的核心需要大量的电力,特别是高涡轮增压时钟,这对以前的Alder Lake芯片来说已经是一个问题。AMD也将在几周内为HS和U系列CPU推出第一批4纳米芯片(凤凰),但它们的TDP范围较低,在~25-80瓦之间运行。

下面的结果为ROG Zephyrus Duo 16在涡轮增压模式(130/100瓦)下的结果,对于ROG Strix G17使用性能模式(120/90瓦特)以及涡轮模式(125瓦特)。

单核的性能和效率

我们从原始单核性能开始,新的Zen4核心比旧的Zen3+型号有明显的优势,如Ryzen 9 6900HX.我们的单核基准测试显示,Ryzen 9 7945HX的平均优势为22-26%。Ryzen 9 7945HX,这是一个非常令人印象深刻的结果。这也意味着AMD与新的猛禽湖HX芯片大致持平,如酷睿i9-13900HX.这款酷睿i9-13980HX另一方面,受益于更高的涡轮增压时钟,比Ryzen 9 7945HX略快,尽管3%至7%的平均优势已经不大。

看看这些结果,你不应该忘记,AMD Zen4核心在单核测试中需要约27瓦特,新猛禽湖HX CPU的性能核心约34-36瓦特,这意味着AMD芯片的原始CPU效率要比英特尔好得多。我们已经提到,在华硕的AMD系统上,用外部屏幕进行测量需要使用dGPU,所以下面的结果并不完全具有代表性,但我们还是想展示一下。如果你是一个非常积极的人,你可以说新的Ryzen 9 7945HX仍然与英特尔猛禽湖-HX芯片(运行iGPU的地方)相当,即使激活了dGPU。

AMD系统的效率结果再次受到活跃的dGPU的影响,但由于多核负载时的总体消耗较高,这里的影响要小得多。在Turbo模式下运行的两个Ryzen 9 7945HX芯片比目前的Raptor Lake i9-13950HX效率高约35-45%,而在120/90瓦特下运行的Ryzen 9与英特尔相比差距增加到60-70%。AMD也非常接近于目前的Apple M2 Max(也是5纳米)。

在较低的TDP水平和电池电量下的多核性能

除了最大性能外,我们还对较低功率限制下的多核性能感兴趣。我们使用应用程序Throttle Stop来调整英特尔型号的功率限制,而我们使用预装的Armory Crate软件中的手动性能模式,为华硕ROG Strix G17.

图中显示了Cinebench R23 Multi在55瓦特、80瓦特、100瓦特、115瓦特、130瓦特、150瓦特和170瓦特的固定功率限制下的结果。请注意Ryzen 9 7945HX在我们的测试中只消耗了127瓦特。Schenker XMG Neo 17的工程样品中的Core i9-13900HX也被限制在130瓦特(取决于GPU,配备RTX 4080 Laptop或更高的Neo 17的SKU达到更高的CPU消耗数据)。三种处理器的比例非常相似,但图中也清楚地显示了Ryzen 9 7945HX的主要优势,甜蜜点实际上是在80-100瓦特之间,与130瓦特相比,性能赤字相当小。我们还在下面的表格中列出了分数。酷睿i9-13950HX和酷睿i9-13980HX的数字基本相同,所以我们没有将酷睿i9-13950HX列入上图。

我们想提及的另一个方面是电池供电时的多核性能有限。各个笔记本电脑型号之间显然存在差异,但几乎每一个设备在你用电池运行时都会明显限制CPU的性能。ROG Strix G17中的AMD CPU ROG Strix G17中的AMD CPU,例如,可以在短时间内消耗高达90W的功率,但也有频繁的下降,CB R23 Multi得分~15000分显示,电池性能降低了50%以上,基本可以与 Apple M2 Max.然而,英特尔机型的情况也没有好转。

闲置功率消耗

我们还在两个系统上以相同的电源设置检查了空转时的CPU封装功率。英特尔的酷睿i9-13900HX在这方面表现更好,平均消耗5.8瓦,而AMD Ryzen 9 7945HX消耗了42%,约8.3瓦特。我们对Zen4笔记本的两篇评论也显示在实际情况下电池运行时间短。显然还有更多因素需要考虑,但AMD绝对应该努力改善这种情况。现在看来,由于效率高的核心,英特尔在这种情况下有优势。

结论--AMD Zen4是目前卓越的CPU

我们在测试后的结论相当简单:AMD目前为强大的笔记本电脑提供了最好的移动处理器。英特尔在单核情况下的性能数据确实略高,但这个个位数的优势是由更高的功耗支付的。猛禽湖-HX芯片的另一个优势是,由于效率高的核心,空闲消耗较低。

新的Ryzen 9 7945HX在多核测试中羞辱了猛禽湖HX型号,特别是考虑到消耗数字。如果单看性能数字,英特尔仍有竞争力,但只有在设备(如微星GT77 Titan)中,CPU的消耗量可以超过170瓦。这对冷却解决方案来说是一个巨大的挑战,你通常会因此而面对巨大的风扇。Ryzen 9 7945HX最令人印象深刻的结果是在80-100瓦之间,芯片仍然比许多功率限制更高的Raptor Lake-HX系统快。

Ryzen 9 7945HX是新Zen4内核的效率和性能的一个令人印象深刻的展示。在80-100瓦之间的范围内,结果仍然令人印象深刻,与一些最快的猛禽湖-HX CPU相比仍然具有竞争力。

我们没有评估集成显卡芯片,但这些CPU只与独立显卡结合发货,所以iGPU的性能其实并不重要。比较不同型号笔记本电脑的游戏性能也很棘手,因为其他组件,如内存,特别是GPU及其功率限制发挥着重要作用。不过,我们对华硕两款采用AMD技术的笔记本电脑的审查并没有显示出任何性能问题。

这台Ryzen 9 7945HX对笔记本制造商来说也非常有趣,因为它以更低的功率限制提供与英特尔芯片相当的性能。这为冷却留下了更多空间,无论是更强大的GPU还是更安静的风扇。如果我们现在必须选择一款功能强大的笔记本电脑,我们会选择配备Zen4处理器的笔记本电脑,但最大的问题还是供应问题。你现在就可以买到第一批配备Zen4的笔记本电脑模型,但与猛禽湖-HX系统相比,模型的数量要少得多。未来几个月将显示出AMD是否能出货足够数量的Zen4 CPU。
