AMD firmly believes that they can improve gaming performance with Ryzen optimizations as all the games we tested with were optimized on Intel, so they feel the testing is one sided right now. They also have a Windows Driver coming in approximately one month that will help performance as the Windows High Precision Event Timer (HPET) isn’t playing nice with the SenseMI sensors that poll the CPU status every millisecond.

“AMD expects to create a simplified solution in the next month to set a Windows profile that pairs the optimum performance experienced in the High Performance power plan, with the energy efficiency experienced in the Balanced power plan.” – AMD
Sorry, but what a bloody joke. That's right, invalidate everyone's testing because you DAMN WELL KNEW there were issues and launched the platform anyways. Sorry, this infuriates me to no end. That's AMD for ya; don't achieve the performance you wanted....and then tell everyone that after years in development they have to wait just a bit longer because they MAY have something just around the corner that improves things.

See comment above. That's a completely inexcusable statement from AMD. They should just admit their memory controller has limitations rather than looking like they didn't properly QA their platform before a public launch.

I think you are completely disregarding what Ryzen has so far achieved in terms of both IPC, single threaded and multi threaded performance. This is a brand new platform and like most platforms there are optimizations and work still to be done. Why are you just focusing on one aspect or things to fault them for? AMD never said that Ryzen will be as good as Kaby Lake in single threaded or gaming. Ryzen competes with Broadwell-E and Haswell-E and that's what it's intended for.

And Broadwell-E has a superior memory controller? Haswell-E has a superior memory controller as well? Again this is a brand-new platform and launch. Of course there will be optimization and work needed. I think this should be revisited say half a year from now or a year from now and see how mature the platform has become.

I see SKY's point though. If they knew there were issues like this, they should have delayed the release. There wasn't any good reason to rush, since AMD hadn't been a player in a few years, so what's a few more months of development time?

Sure, there are optimizations but remember that what we are talking about (Windows HPET for example) are fundamental functions of an operating system that seem to have been overlooked. That's a problem.

I'm not saying anything is inferior, just limited in functionality. There's always optimizations but there's also the matter of setting unrealistic expectations that said optimizations will have a drastic improvement upon performance.

Of course they do.

Despite being quad-channel, which increases the load, they can both easily handle dual rank memory modules up to DDR4-3200.

Excellent review Sky!

Just a quick question, did you do any gaming benchmarks above 1080p? I've gone through a couple of reviews and it seems odd but Ryzen seems to kick it up when at 1440p+ for DX11 and DX12 titles.

This is a little less exciting than I thought. I'm with lowfat on the PCIe lanes. But it's still a pretty good step in the right direction for AMD. With all the G, X, M, etc I see AMD's naming convention still likes to be a bit on the confusing side....

But it's definitely good news for the consumer. I don't know that it'll put much downward price pressure on Intel's top offerings, but any news is pretty much good news on that front.

It was already known prior to release that Ryzen was limited in terms of what it could support with DDR4 especially when you are using all 4 DIMM slots or in terms of speeds. This is a minor and moot point considering that it's not a hardware limitation but rather requires firmware optimizations in the form of bios updates.

Can Broadwell-E handle all 8 DIMM's with 16GB densities at DDR4-3200? I don't think neither Broadwell-E or even Haswell-E can handle that due to IMC limitations and that's been the case with Intel IMC processors for a while (when using all memory banks).

Thanks for the info on the memory rank issue. I am doing a cost estimate project with my students and they build out PCs on paper as a part of the project...I have not covered memory with them yet, so I will add the memory rank info to the lecture.
