AMD RyZen CPU Architecture for 2017

PCGH found the reason why Ryzen and Broadwell-E have such terrible minimal and average FPS, the game simply doesn't compute a lot of the particle effects if you have only four physical cores, SMT doesn't matter.
This only happens in the game itself, the integrated benchmark doesn't scale based on CPU cores.
If you disable 4 cores on Ryzen the FPS are automatically increasing because the game scales down the graphics.

That's crazy. 1 point for the integrated benchmark which doesn't have this issue :D

Nothing compare to tomb rider.
 
Unfortunately, for consistency sake, I think CB only tests multiplayer on empty maps, So there is little useful data here.
...

CB testing shows all AMD CPUs taking a massive hit under DX12, here the API appears to be bound by single threaded performance as the 7700K climbs it's way to the top, while In DX11 core count seems to be the determining factor (weird I know!). This could be a direct consequence to them testing empty maps. As DX12 doesn't really exploit it's multi-threading capabilities when not much is going on on the screen. For comparison sake, PCGH managed to show that DX12 is heavily CPU dependent in Battlefield 1(scales more with CPU cores than DX11).
It looks like the answer might be in the fact that AMD does not have any high end GPU on the market and everyone is using Nvidia GPUs. Look at the video linked by Malo below your original post.

Results are mind boggling.

I kind of pity AMD. Now that they have a decent cpu on the market they will still fight an uphill battle against software. But its their own fault i guess. Not having a decent product on the market for several years (CPU) is hurting them bad. Vicious circle...
 
Yes and tbh the CF is good for comparing but its not representative of real world cuz very few users use them. Hope with vega things change.

BTW how ironic when everyone tested with high end Nvidia GPU to make the test "fair" was actually the wrong thing...I like that guy not because he says AMD is better but because he saw something that didn't add in this mind and he try to go deeper and make a real effort to find out. I like that thinking.

BTW2(lol) Should review also account input lag in their reviews? everyone talk about the "responsness" of ryzen so maybe an input lag bench should be added.

He is clearly measuring CF efficiency and scalability under different CPUs and APIs. A good test will stick to a single GPU and start from there. Not introduce a highly unstable, unreliable and non linear variable. He jumps to conclusions too quickly before doing any proper exclusion. Everyone knows DX12 path is faster on NV than AMD in Rise of The Tomb Raider.

He did do some testing with a single RX480 as well in the video showing how close it gets to a 1070 in DX12.

He also show how unreliable the game performance is depending on where you are or what ur looking. you should see the whole video.

That was a CPU limited area, It's only natural that GPUs pack together a little closer in these situations.
If we are going by the numbers here are some:
The 1070 is faster than FuryX @1080p DX12 by this margin:

David i think you are missing the point. From the video you can clearly see that the poor ryzen performance is not hw but sw related. And this was the whole point. Poor Dx12 nvidia drivers contributed to weak cpu performance. I new there is some potential (for gaming) in new AMD cpu i just did not expect those kind of results. As a side note you can clearly see that amd has a decent cpu but needs to put a lot of effort into sw side of the equation to make it shine.

Ryzen is limiting the GTX1070. There would be no difference with a GTX1060 instead of the RX480.
Here is a comparision between a GTX1060 and RX480 with a i7-7700K:

GTX1060 is slighty faster in the same spot.
 
I can understand people don't want to accept some of the preliminary results, but AMD will have a high end GPU on the market soon, and then everybody will know about Nvidia DX12 driver performance. Ryzen is an excellent CPU which just seems to be bottlenecked by both drivers as well as intel optimised games. That will change soon. Tomb Raider is a Nvidia sponsored game, imagine how normal games would perform on Ryzen without Nvidia drivers..
