AMD confirms that Windows 10 does not have a Ryzen scheduling bug

 
After conducting their own internal testing, AMD has confirmed that Windows 10 does not have a thread scheduling bug when used with their new Ryzen CPU architecture.
 
This means that AMD fans should not expect an update to Windows 10 that will offer dramatic gains in Ryzen CPU performance, though the company remains optimistic that there can be some beneficial optimisations for both current and future applications.  
 
 
 
 We have investigated reports alleging incorrect thread scheduling on the AMD Ryzen processor.
 
Based on our findings, AMD believes that the Windows 10 thread scheduler is operating properly for “Zen,” and we do not presently believe there is an issue with the scheduler adversely utilizing the logical and physical configurations of the architecture.

AMD has also stated that Ryzen users should use Windows 10 in High-Performance mode, which will prevent Core Parking and enable faster frequency changes. By mid-April AMD plans on releasing an update which will enable better Ryzen performance in Balanced power mode, though for now, performance mode offers the best user experience.

AMD have confirmed that both the 1700x and 1800x have a 20c temp offset. They run 20c cooler than the reported temps.

This would explain why Tom couldn't see so much heat haze rising from the cooler in the review.

Does this mean they can be overcooked higher than 4.1Ghz now?!Quote

Depends on how many extra . of volts you could put in aslong as you can get rid of the heat i suppose. But wendell has managed to get 4.3 ghz on a taichi board whilst on linux. Having the ability to remove that fan offset, of which i have no idea why we have it will be key though, and on a bios level.

But dont just think about the speed of a ryzen through its pure ipc, there is something emerging with these chips that the infinity fabric is actually varied by ram speed, so the faster the ram the faster the cpu works internally via the infinity fabric working faster.

So thats something to keep an eye on, and also something in that, it turns out that whilst the shed isnt off in seeing the cpu, its still doesnt see it as a 2 cpu system, well it does and it doesnt but long story. If they can make the shed stop randomly jumping work and if they can make games not try and put work on cores that are related on the different blocks then we should see a good inprovment in game performance.

They also need to figure out what it is about windows 7 that makes ryzen so much faster in it than on windows 10.Quote

AMD have said that the difference between Win 7 & 10 is based on the OS architecture alone.Quote

Yes and the difference between a gtx 980 and a gtx 1080 is architecture alone, point is what is it in 7 that makes it faster, learn from that, update windows 10 to have that effect.Quote

It is not faster in W7. MS doesn't even support Ryzen in 7.Quote
