Last week, computer processor maker AMD revealed that Windows 11 is adversely affecting its processors, which can result in reduced performance. Now a TechPowerUp report has said that AMD processor PCs are experiencing much higher latency after installing the latest version. Windows 11 update.
As officially revealed by AMD previously, after installing Windows 11, measured and functional L3 cache latency in some of its processors increasing up to three times, which affects the access time of applications sensitive to memory subsystems. The performance issue is as high as 15% in certain games, but generally the impact ranges from 3% to 5%.
Another issue stated by the company was that preferred cores do not preferentially schedule threads on the fastest core of a processor after upgrade. This problem hampered applications sensitive to the performance of one or some CPU threads. According to the company, the performance hit was detectable on processors> 8 cores above 65W TDP.
TechPowerUp looks at the latency of the L3 cache on your AMD Ryzen 7 2700X at around 10 nanoseconds and Windows 11 increased it to 17 nanoseconds. Although the patches for both AMD processor The issues will be released this month only, Microsoft is expected to address the L3 cache issue next week.
