*** AMD "Zen" thread (inc AM4/APU discussion) ***

The yellow bar (Ryzen under LN2) is second from the top, looking very close to the top one, but top one could be anything :/

However what we know
a) the default top on on the C15 is a 12c/24t Xeon X5650 @ 2.66ghz with score 1279cb
b) Ryzen going to be faster than IB core, not 30% slower (even the FX8350 can do better) especially with LN2 cooling it.
So they have a custom run, and the top one has to be some very big current CPU eg B-E 8-10c one....

FYI the mobo is the Biostar one

That's a very tidy looking motherboard. Gotta say AMD have managed to make me interested in building a new pc. Only thing really putting me off building a new pc, is that graphics card prices as crazy these days and large >500GB SSD's are very expensive too.

It's going to be interesting to see how well Ryzen responds to memory overclocking and timings etc.


p.s. does anyone know if Ryzen has the appropriate decoder for the 4K netflix codec? (the one that currently only Kaby Lake supports)

Only Kaby Lake supports that atm, not even graphic cards, since both RX and GTX10xx fail also.

RyZEN doesn't have a GPU / IGP so doesn't have any video decoders. So on a ryzen setup this would be down to the paird graphics card.

Out of interest any idea what codes / profile does Netflix 4k use?
 
This is what I just grabbed from an article.

In an effort to placate the studios, Microsoft introduced "PlayReady 3.0" with the Windows 10 Anniversary update. PlayReady 3.0 is a hardware-based DRM (digital rights management) system that requires dedicated decoding hardware, either on the CPU or on the graphics card, preventing the video stream from being captured in software or via an external capture device.

There's also the matter of hardware decoding support for 10-bit HEVC, the 4K codec used by Netflix and other streaming services. Currently, only Intel's seventh generation Kaby Lake processors support 10-bit HEVC decoding. Older sixth generation Skylake CPUs only support 8-bit HEVC decoding. Technically, Nvidia's 10-series graphics cards—including the GTX 1080, GTX 1070, and GTX 1060—feature 10-bit HEVC decoding and PlayReady 3.0 support, but aren't listed as compatible.

So from that, I'm still not sure whether the PlayReady 3.0 needs to be in the CPU as well, or just the GPU (which also needs to support 10-bit HEVC).

I'm gonna go out on a limb and guess that if RyZen doesn't have the PlayReady 3.0 hardware DRM then that part mustn't need to be on the CPU as well, just where the hardware decoding is taking place. (which would actually make sense)

Anyhow, I think this particular subject may be leading off topic slightly.

I don't know if this site can be trusted, but have stated that only 8c16t processors at release. This might explain why there are only prices for R7 processors at the moment.

Disappointing if that turns out to be the case. I think I read a link earlier claiming that the 8 cores were dropping on the 28th with the rest on the 2nd of March - can't remember where that was now, possibly a load of rubbish too.

It would have been nice to see at least one CPU per core count at launch.

It looks like pascal based GPUs support play ready 3.0 (http://www.geforce.com/whats-new/articles/pascal-video-playback)

This also means that as polaris based amd GPUs should also be able to support it eventually (as they can decode 4k 10bit HEVC)

Zen itself won't as its just a CPU (no video codecs) and as far as I can tell (as any pascal system should support it) is cpu independent.

But what a brilliant DRM system. That is properly available on one CPU.... That was released only in the last few months.....

OK if that's true, then this CPU is looking pretty epic based on this older bench run I've seen of a 5820K (Source: Techpowerup https://www.techpowerup.com/forums/threads/share-your-cpuz-benchmarks.216765/):
5820K @ 4.5 GHz
5820k_info-png.68518
5820k-png.68517


EDIT:
Fiddled with RAM and CPU cache clocks and timings with virtually no gains. So I clocked them back to stock :D My RAM is at 2400MHz 15-15-15-35.

And an overclock at 4.8 GHz :D

That Ryzen being CPU-z'd is also 6c12t and much lower clocked than the 5820k!
