AMD Says The Windows Thread Scheduler is "operating properly" for Ryzen.
In a blog post that is sure to stun many users expecting a "thread scheduler patch" in modern Windows versions for AMD Zen-based CPUs, AMD has apparently investigated the reports of thread scheduling issues and found 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."
So, if you were expecting a Windows 10 or maybe even 7 patch to address some performance concerns, don't hold your breath. The company notes that they tested both Windows 10 and Windows 7 and they "do not believe there is an issue with scheduling differences between the two versions of Windows." In other words, 7 is already ok as far as scheduling, no patch required.
The company does still recommend users utilize the "High Performance" plan in their Windows setup for best performance, claiming the software management of CPU speed interferes with Ryzen's native management. There may be an update forthcoming for the Windows "Balanced" plan to fix how it operates with Ryzen, but there will not be a scheduler update planned as of now.

Microsoft: "We are working on the issue"
AMD: ¯\_(ツ)_/¯
Watch the whole video, they talk about something that might be an issue though.
o_O
There are issues...
you sound like a fanboy tbh :shadedshu::roll:I'm out you win :rolleyes:
Another 5-10% wouldnt hurt.
I actually find Ryzen to load windows faster than my Intel rigs, and it seems to have a bit less latency in doing certain things. The only thing that is a bit disappointing with Ryzen is its relatively low clockspeed. There are ZERO other problems, really, at this point, that I can find.
Most are relating problems form launch-day reviews, but there have been BIOS releases since those reviews have posted that have had some impact that everyone else seems to ignore. :P
Editorial on hypetrains has been long in the works, coming soon.
Something is up...
Physical\Logical core assigning is fine (being honest, this is to be expected considering its productivity benchmarks).
Games that do their own core scheduling will suck somewhat until patched. Not that I think it'll matter that much going forward unless you're CPU limited (and by then, you probably already have decent fps).
Still no response on fabric thrashing going across core complexes with cache misses and whether this can be fixed by scheduler updates.
AMD really needs to quantify and market its advantages ASAP. They do indeed have a product that is better than the competition's in every way - it's their game to lose.
Its a big reason why Intel's 8 Core is a 150w part whilst AMD's is all the way down at a 65w part for the 1700 (there are exceptions to this, like Intel's Xeon-D and Atom SoC range, but they do this by restricting each cache to a coherent pair {which is technically even worse than Ryzens here if your using the monolithic argument}. Realistically, that means there is a cap on the amount of CPU cores that can be used in a monolithic design before your TDP and die size budgets start going crazy.
One would expect NUMA addressing to be used for this. Shrug.
People said AMD supporting 64-bit on their PCUs was too early and unneeded and the same applies to the number of cores Ryzen has... it's early to the game. Intel can release a chip with more cores into its mainstream platform if it wanted to, but in the time it takes them to do so, AMD may be able to release a new Zen chip that scales up the frequency, and then Intel and AMD might be on-par with each other for performance for enthusiasts.
It's AMD that dictates that, BTW. They say Ryzen is a mainstream product, so that's what it is.
the Raven Ridge APUs are for mobility and AIO uses, not mainstream. There will be some models that make it into the AM4 desktop platform for sure, but APUs are not a "mainstream" platform on their own.
You can obsess about labels all you want, but AMD's "Mainstream" chips are beating Intel's "Premium".
