From the pictures here, it seems like all ASRock boards are only supporting DDR4-2666?

There s some progress, though, not so long ago i did read that they werent even functional...

That being said those SFFs are very nice and Zen will be the only 8C/16T offering in this PC format.

Did you see one of them running? All running PCs I've seen had a prototype, or OEM, board, like the red GOLEMIT thing. And these pictures are the first real confirmation of any RAM speed I've seen.

Dual channel DDR4 won't be bottleneck for 8-10 CUs in Raven Ridge if it can fully utilize RAM @3000 MHz or above. And those modules are not so expensive and will probably be cheaper by the time RR is released

It would.
512SP / 8 ROP "Spectre" found in Kaveri / Godavari still scales at 96GB/s bandwidth. That's equivalent of DDR-6000 on a 128-bit bus. Spectre was a GCN2 GPU, so it lacked the delta color compression implemented in GCN3. Vega will most likely have an improved compression, but still the "non-bottlenecking" bandwidth requirements are greater than you can ever achieve with DDR4 on 128-bit bus.

Yes, but memory controllers on old(er) APUs/CPUs were not so good, comparing to Intel's. There is/was a lot of room for improvements in that area also. If GCN IGPs were in Skylake CPUs, it would be much faster :)

Okay, I'll grant you that Intel-level memory controllers would improve things, but . . .

ding ding ding, there you have it folks.

Even improving the mem controller won't be "enough".

Agreed but you dont need to have higher performance than to be able to play games at 1080p at low/medium settings. So ZEN with Vega iGPU graphics and 3200MHz+ DDR-4 memory could be able to play games at 1080p medium settings and that will be equal or even better than XBone ;)
So imagine to have a mini-itx PC SFF case with Quad Core ZEN + iGPU only graphics and be able to play games at 1080p at $300-400 for the entire system. It could revolutionize the desktop again ;)

On the other hand, some of Vega's improvements should pretty significantly reduce memory bandwidth requirements, and Raven Ridge is supposed to be Vega based.

These two should reduce memory bandwidth requirements^

This one MIGHT, depending on exactly how it works and what it does, allow less bandwidth to still provide acceptable performance. Maybe even have access to the L3 cache on the CPU through the infinity fabric to help coushin things a bit.

Polaris also reduced memory bandwidth requirements not just from the improved compression algorithms, but also doubling the L2 cache of the GPU and improving its use.

Vega would definitely improve on Polaris in terms of memory bandwidth requirements. But still a 1024 sp GPU on a Raven Ridge desktop APU would need around 128 GB/s to perform to its full potential. Dual channel DDR4 3200 provides 51.2 GB/s bandiwdth. Thats around 40% of required bandwidth. AMD has to either stick with a 512 sp GPU or just go ahead and add a single HBM2 stack. AMD talked about High bandwidth cache controller as an important feature in Vega. I think the APU is the one which benefits the most from the use of HBM as cache. AMD would permanently solve the bandwidth problem by using HBM as cache for the GPU.

128GB/s would be more than AMD provides the RX 460.

I do believe a Vega based GPU with 11 CU's could perform near its full potential with 50GB/s of bandwidth.

Well, I have played a lot of old(er) AAA games with my A10-7850K and 2133MHz DDR3. I think Sniper Elite III was the most demanding one. Of course even with high speed DDR4 it won't be fast as dGPU with GDDR5, but it won't be that much slower. I think the best we can compare is Spectre vs HD 7730 or HD 7750, though 7730 is 6 CU chip and 7750 has 16 ROPs, while Spectre has 8.

http://www.tomshardware.com/reviews/radeon-hd-7730-cape-verde-review,3575-4.html

When you compare 7730 DDR3 vs GDDR5, GDDR5 model has 2-3 times higher bandwidth and yet is only ~30% faster. So I think DDR4 @3000 MHz with ~50 GB/s will be good enough to justify buying APU instead of dGPU if prices are competitive also.

But just to add that intel will be offering 2c/4t Pentiums for $60-70, and APU will require more expensive, faster DDR4 kits, while if you go for dGPU, it's ok to go for one slower RAM module and save ~$20. And RX 460 costs $100. So in total you can buy budget gaming setup for ~$200, while high-end APUs are currently around $150. Even if their price is <$120, with faster DDR4 kit, setup would cost around $180. I'm not sure even with 1-2GB HBM IGP would be faster than RX 460, and would certainly be more expensive. So I think future APUs will have to fight the competition with their CPU performance and/or TDP, not with GPU

Hbm2 plus zen and vega can enable a new performance level for the ultrabooks /sub 50w. Its the only radical perf uplift in sight and it is certainly expensive but i am sure there is a market for it. Be it apple or eg the more expensive dell 13 15 ultrabooks. It is a unique product that enable something new both professional and for consumers. One stack of HBM2 128/256Gb saves tons of power and gives tons of bandwith. Coupled to a vega and a quad zen its a blast.
I will buy it day one. If not several for the family. It will be the standard machine because it can do everything okey from handbrake to bf1 and in a notebook form. I hope we get some hbm2 solution before 7nm 2019 but am not sure.

Check this out: AMD RyZEN Blender Benchmark
107 CPUs tested in Blender running 100 samples.
It is interesting to see top 100 with this test. Ryzen SR7 - 3.4 Ghz (No Turbo) : 25 seconds - Samples 100 it's on 10th place (the list is updated)

AMD - AMD RyZEN - 3400 MHz (8c/16t), Windows 10, 100 samples - 25s
Samba - Intel Core i7 5960X - 3400MHz (8c/16t), Windows 10, 100 samples - 25s

- According to this, Haswell levels.

From the same post:
"matose (nickname) - Intel Core i7 6950X (procesor) - 4200MHz (10c/20t) (frecventa si nuclee), Windows 10 (OS), 100 samples (setare) - 16s (rezultat rotunjit)"

Assuming the perfect scaling with clocks and core count (best case scenario for BDW-E, not realistic), BDW-E 8C/16T @ 3.4Ghz should score 16x10/8x4.2/3.4=24.7 or practically the same as 16T Ryzen at the same clock. Scaling with clock and core is not perfect though so the score would likely be lower( higher runtime).

edit:
  • matose - Intel Core i7 6950X - 3400MHz (10c/20t), Windows 10, 100 samples - 20s

Seems like 8C/16T BDW-E should score ~25s as predicted. 20x10/8~=25s.

So also broadwell is at haswell level?

Guys, how to test this?:D Any tip? Im ready for Ryzen now...



And memories at older times witrh Vishera or small strong 5150 Athlon :)

Haha.. easy now, truth is likely around haswell-broadwell... when did you narrow zens performance down to the 0.001 percentage? I didnt get the memo but would like to read it :).
(no.. assuming perfect scaling isnt it imo).

This forum/site (the source I have pointed) is like anandtech in Romania, a good source of information, legit.

You could always send me your "gear" and I could test it. I mainly want the hat though.

I just wish vega was launching at the same time, then I could get a whole new system all at once.

Pretty good for the SL/KL cores given the lack of threads...
Wonder what a 4c/8t Ryzen could do?
