in the light of AMD's own investigations and other 3rd party investigation into Windows' 10 ability to properly identify Ryzen CPUs and assigns threads accordingly, AMD's Robert Hallock posted on AMD's blog:

Thread Scheduling
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.
 
As an extension of this investigation, we have also reviewed topology logs generated by the Sysinternals Coreinfo utility. We have determined that an outdated version of the application was responsible for originating the incorrect topology data that has been widely reported in the media. Coreinfo v3.31 (or later) will produce the correct results.
 
Finally, we have reviewed the limited available evidence concerning performance deltas between Windows® 7 and Windows® 10 on the AMD Ryzen™ CPU. We do not believe there is an issue with scheduling differences between the two versions of Windows.  Any differences in performance can be more likely attributed to software architecture differences between these OSes.
 
Going forward, our analysis highlights that there are many applications that already make good use of the cores and threads in Ryzen, and there are other applications that can better utilize the topology and capabilities of our new CPU with some targeted optimizations. These opportunities are already being actively worked via the AMD Ryzen™ dev kit program that has sampled 300+ systems worldwide.
 
Above all, we would like to thank the community for their efforts to understand the Ryzen processor and reporting their findings. The software/hardware relationship is a complex one, with additional layers of nuance when preexisting software is exposed to an all-new architecture. We are already finding many small changes that can improve the Ryzen performance in certain applications, and we are optimistic that these will result in beneficial optimizations for current and future applications.

 

so ... ladies and gentlemen - do not expect AMD / MicroSoft to release a W10 patch that will magically fix Ryzen's poor gaming performance - it is what it is and nothing will change that

 

however, AMD plans to release a patch that addresses the power plan issues, in April

 

so why W7 performs better?

because W7 is the better OS

Can I just bottle up the tears of AMD fanboys?  They taste delicious and I want to be able to enjoy them year round.

I don't think poor is the right word, more over underwhelming maybe at 1080p.

They also state

For the remaining outliers, AMD again sees multiple opportunities within the codebases of specific applications to improve how this software addresses the “Zen” architecture.

We have already identified some simple changes that can improve a game’s understanding of the "Zen" core/cache topology, and we intend to provide a status update to the community when they are ready.

[The Sloth]

look i said this for x99 launch and i will say it for ryzen launch, give it 6 months minimum to a year to get all the issues resolved. for now if you are doing creative work get a amd ryzen, if you are gaming get a 7700k.

Does it, I never paid attention to Bulldozer back then.

 

Considering how shoddy the motherboard BIOS still are, I'll still waiting to see what'll happen in a few months.

AMD will make Bulldozer great again^TM - 6y later and still waiting

Ryzen is not Zambezi/Bulldozer, its gaming performance is not poor. It's just a little behind Intel, in ways that mostly aren't noticeable. Not too different from how Intel's high-end platform is behind its mainstream platform.

[TechGod]

But if this was Intel you'd ignore this or make excuses. Again, I've asked you this before. How did AMD hurt you?

[goodtofufriday]

Lol poor gaming performance?? Well damn son what future tech you running that r7 runs poorly

And Intel has only improved on Haswell a little. So AMD is only a little behind in gaming performance, because that's what the benchmarks show.

 

They made up most of the deficit there, and are offering greatly superior non-gaming performance per dollar. And with very reasonable power consumption.

[HelplmChoking]

Okay, for the thousandth time, the currently released Ryzen chips are not competitors to the 6700k/7700k CPUs in anything other than price. The 1800x competes with the 6900k as a multithreading workhorse at half the price. Lower core count Ryzen chips are coming, likely with higher clock speeds and greater OC abilities. Those will compete with the 7700k's of the world, likely delivering 1-5fps less for much lower costs.

Exactly, and within 4 years, Intel managed to improve IPC by a whopping 5-8% when comparing Haswell to Kaby. DDR4 gave the vast majority of that improvement. Ryzen is fine. It's not as fast as Intel for gaming, but it's "good enough" and cheaper when compared to Intel's "heavy lifting" CPU's. This means people that want to do a bit of both (gaming and pro-sumer work) might find Ryzen to be a compelling option. Granted, this is likely a pointless endeavor, seeing as you will always hate AMD with a passion, and likely have me blocked as well (since objective thinking goes against your belief system).

Yeah and if I go out it's not really raining, it's just a little humid with some water precipitation that's all.

except it's ~14% 

Ryzen on DDR4 does less than Haswell IPC .. or you did forgot that
