The first update from Windows 11 seems to make them worse performance with processors AMD Ryzen, which already encountered some problems when launching the new Microsoft operating system.
A few days ago there was indeed talk of possible performance problems with some Ryzen processors on Windows 11, but apparently the first update instead of solving, it further emphasized the gap, further increasing the latency of the L3 cache of the CPUs in question.
The TechPowerUp site has in fact measured the latency of the L3 cache on a Ryzen 7 2700X, starting from 10 nanoseconds on Windows 10 which became 17 on Windows 11 and almost 32 after the application of the first update.
This is no small difference, so some have already been announced patch which will be available by the end of the month and will aim to solve the problem: the one produced by Microsoft could debut on October 19, while that of AMD will arrive a few days later.
The birth of a new operating system inevitably brings with it some unexpected, but in the case of Windows 11 it seems strange given the list of compatibility of the processors somewhat reduced, evident result of a skimming carried out precisely to avoid such situations.
Speaking of Windows 11, here’s an easy guide to make the most of it.
