一 | 1月10日：在AMDCES今天凌晨1点的主旨演讲中，这位官员没有宣布期待已久的7NMZen2处理器。 A team of scientists has discovered a likely explanation for why one may feel exhausted after engaging in intense cognitive work.,In their study, published in the Current Biology last week, the researchers argue that intense cognitive work, when it lasts for several hours, results in the buildup of potentially toxic byproducts in the prefrontal cortex part of the human brain, which then affects a person’s behavior.,“Influential theories suggested that fatigue is a sort of illusion cooked up by the brain to make us stop whatever we are doing and turn to a more gratifying activity,” Mathias Pessiglione of Pitié-Salpêtrière University in Paris, said as quoted in a news release by Cell Press. “But our findings show that cognitive work results in a true functional alteration—accumulation of noxious substances—so fatigue would indeed be a signal that makes us stop working but for a different purpose: to preserve the integrity of brain functioning.”,During the course of their research, the team employed magnetic resonance spectroscopy to monitor the brain chemistry of two groups of people during a workday, with one group performing easy cognitive tasks while the other engaged in more complex mental activities.,Only the latter group ended up exhibiting signs of fatigue, as well as a tendency to favor “options proposing rewards at short delay with little effort,” as the news release put it.,AmericasChild Survives After 7 Minutes Without Blood Flow to Brain During Surgery, US Cardiologist Reveals11 August, 16:41 GMT,Furthermore, members of that group had higher levels of glutamate in the synapses of the prefrontal cortex, leading the researchers to suggest that the accumulation of glutamate “makes further activation of the prefrontal cortex more costly,” and thus a mentally exhaustive workday makes cognitive control more difficult.,Unfortunately, there seems to be no fancy way to deal with this problem other than the tried and tested method that is probably as old as history itself.,“I would employ good old recipes: rest and sleep!” Pessiglione remarked. “There is good evidence that glutamate is eliminated from synapses during sleep.”。AMD首席执行官苏子峰（su zifeng）表示，第三代Ryzen处理器将于今年中发布，并将是第一个支持PCIe4.0的处理器。AMD 300/400 AM4主板也可以通过BIOS升级PCIe 4.0。
二 | 国外媒体深入分析了AMD在发布会上展示的8核处理器，认为将有12核16核版本。AMD显示了一个名为“Matisse”的7-NM CPU代码，封装了两个芯片：一个由TSMC制造的8核7-NM芯片和一个由Grofford提供的带有双内存控制器和PCI通道的14纳米输入/输出芯片。外国媒体认为这个CPU上还有另一个CPU死机的空间。这是外国媒体提出的一个想法。_第二个CPU芯片的SMT痕迹也可以在Guru3d的《外国媒体PC世界》发布的视频中清晰地看到，因此，外国媒体推测AMD在发布会议上展示的8核CPU可能不是最高版本，可能有12核和16核版本。相关阅读资料：AMD 7NM Ryzen处理器年度发布：对PCIe 4.0的开创性支持，AMD Radeon VII发布，首个7NM显卡，Super RTX 2080。
