The first update of Windows 11 brings more “bad news” for these laptop users


Microsoft recently the first update of Windows 11 since its inception, to fix bugs reported by users. This was the first update that Windows 11 Production, Beta, and Release Preview users received at the same time. Although the update was meant to help the user, it instead made it worse. Last week, computer processor maker AMD announced that Windows 11 was adversely affecting its processors, which could result in decreased performance. Now a TechPowerUp report states that the AMD processor Self-powered PCs have much higher latency after installing the latest version Windows 11 update.
As AMD officially announced earlier, it was measured and functional after installing Windows 11 L3 cache latency to a few if its processors tripled, which affects the access time of applications that are sensitive to storage subsystems. The performance problem is up to 15% in certain games, but typically the impact is between 3 and 5%.
Another problem the company reported was that preferred cores did not schedule threads on the fastest core of a processor after the update. This problem hampered applications that were sensitive to the performance of one or a few CPU threads. According to the company, the loss of performance with> 8-core processors over 65 W TDP was demonstrable.
TechPowerUp records the L3 cache latency on its AMD Ryzen 7 2700X at around 10 nanoseconds and Windows 11 increased this value to 17 nanoseconds. Although patches for the above two AMD processor issues won’t be released until this month, Microsoft is expected to address the L3 cache issue next week.
Update KB5006674 for Windows 11 released this week brings the OS build number to 22000.258. The fixes mentioned in the update are relatively brief, and it is rumored that the company will soon be fixing other bugs reported by users.
