联想ThinkPad P16笔记本电脑回顾：RTX A2000现在有了充分的动力
今年早些时候，我们审查了配备RTX A2000的联想ThinkPad P16。当时，图形性能变成了令人失望的低水平，这导致我们建议不要使用这种特定配置。我们对联想工作站的第二次测试表明，联想ThinkPad P16基本上可以成为一台非常强大的笔记本电脑，因为配备RTX A5500的联想ThinkPad P16显示出非常强大的GPU性能。
联想向我们保证，P16在配备RTX A2000的情况下，应该还会显示出更好的GPU性能。怀疑的是： 我们的第一个测试设备出了问题。联想无法复制相应的基准测试结果，所以我们又看了看带RTX A2000的ThinkPad P16。我们重点关注GPU性能，所有其他信息都可以在我们对该配置的第一次详细审查中找到。

性能：Nvidia RTX A2000现在运行速度明显加快
这里测试的配置与第一个测试设备相同： 英特尔酷睿i7-12850HX, Nvidia RTX A2000，16GB内存，和1TB SSD。关于联想ThinkPad P16的其他可用型号的信息可以在 我们的第一篇评论.
测试条件
在CPU性能方面没有任何变化，所以我们不会进一步讨论处理器性能。GPU的情况则不同，联想澄清了这一情况：图形芯片的功率不限于60瓦，但最多可以消耗80瓦。60瓦的数值只适用于CPU和GPU同时负载的情况。
图形卡
有许多不同版本的 Nvidia RTX A2000.较旧的版本只有4GB的内存，例如，我们最近看到一个在 ThinkPad P15v G3.这种GPU的较新型号，比如这里的P16，总是配备8GB。然而，即使是这些较新的GPU，GPU的最大消耗量也会有很大不同：在35至95瓦的范围内，任何事情都有可能。
在ThinkPad P16中，一切都表明图形芯片最多可消耗60瓦，在综合负载下甚至更少。然而，我们今天的测试设备运行的是一个较新的驱动版本，这里的情况看起来有所不同：我们测得在纯粹的GPU负载下，最大功率为80瓦。联想的规格表提到了60瓦，但联想在被问及时确认了80瓦，我们在另一个样本中也确认了同样的数值。
与第一次测试结果的差异很明显：这里测试的ThinkPad P16在3DMark测试中比第一次测试快了约37%，在SPECviewperf中甚至快了47%。与配备RTX A5500的版本相比，仍有明显差距。 版本仍有明显差距。，但差异明显较小。现在P16的RTX A2000变体在游戏测试中的得分也高得多。

排放与能源：联想ThinkPad P16的风扇现在更活跃了
噪声排放
在我们对配备RTX A2000的ThinkPad P16进行第一次审查时，可以注意到，在Witcher 3 测试期间，风扇几乎不运行。这一点现在明显不同。现在主动冷却系统在Witcher 3 测试和压力测试中运行的声音一样大。同样值得注意的是：在这个设备上，风扇在空闲模式下运行的频率也高得多。

温度
ThinkPad P16的新测试装置在负载和怠速状态下的运行温度都比第一款机型略高。特别是负载下的较高温度并不令人惊讶。毕竟，GPU的性能变高了。
在压力测试中，我们无法确定任何节流情况。

消耗功率
为了证实我们的基准结果，我们再次进行了一些能量测量。这些结果与基准测试结果所显示的完全一致：配备RTX A2000和较新驱动版本的ThinkPad P16在负载下显示出更高的能耗，因为GPU被允许消耗更多。特别是在Witcher 3 测试中可以看到这种差异。

结论：联想ThinkPad P16现在用RTX A2000运行得更快了
联想ThinkPad P16是一款非常好的移动工作站--这是我们对配备Nvidia RTX A2000的版本进行首次评测时的结论。我们对配备Nvidia RTX A2000的版本进行的第一次审查的结论尽管我们不得不承认，GPU的性能太低。有了较新的驱动版本和新安装的操作系统，我们可以说GPU手刹的问题已经解决了。尽管Nvidia RTX A2000仍然明显慢于RTX A5500，我们也在ThinkPad P16中进行了测试--现在达到了预期的效果。
现在GPU性能达到了全速：配备RTX A2000的ThinkPad P16毕竟值得推荐。
