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...
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
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
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.

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.It would.

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