Warning: Microsoft's first update for Windows 11 makes AMD system performance 'much worse'
Among the problems with Windows 11 is a worrying issue with reduced performance on some AMD processors. Both AMD and Microsoft are busy working on fixes, but if you were hoping that the first update for Windows 11 was going to help, think again.
With the release of KB5006674, Microsoft has addressed a known networking issue with Windows 11, but has failed to do anything about poor AMD performance. But things are even worse than that. Reports and benchmarks suggest that performance on AMD systems has been even further reduced by this update.
Windows 11 performance is up to 15 percent slower on some AMD processors
With Windows 11 now publicly available the time has come for problems to start surfacing. We have already had reports of reduced performance in games as well as File Explorer using large amounts of memory; now AMD has issued a warning that Windows 11 users with certain processors can expect reduced performance.
The chipmaker has provided information about "known performance impacts reported on Windows 11 when running compatible AMD processors on certain applications". Affected processors include Ryzen 3, 5, 7, 9 and Threadripper (plus Pro variants), and the impact means that performance is reduced by as much as 15 percent.
