The AMD Radeon VII Review: An Unexpected Shot At The High-End
by Nate Oh on February 7, 2019 9:00 AM ESTCompute Performance
Shifting gears, we'll look at the compute aspects of the Radeon VII. Though it is fundamentally similar to first generation Vega, there has been an emphasis on improved compute for Vega 20, and we may see it here.
Beginning with CompuBench 2.0, the latest iteration of Kishonti's GPU compute benchmark suite offers a wide array of different practical compute workloads, and we’ve decided to focus on level set segmentation, optical flow modeling, and N-Body physics simulations.
Moving on, we'll also look at single precision floating point performance with FAHBench, the official Folding @ Home benchmark. Folding @ Home is the popular Stanford-backed research and distributed computing initiative that has work distributed to millions of volunteer computers over the internet, each of which is responsible for a tiny slice of a protein folding simulation. FAHBench can test both single precision and double precision floating point performance, with single precision being the most useful metric for most consumer cards due to their low double precision performance.
Next is Geekbench 4's GPU compute suite. A multi-faceted test suite, Geekbench 4 runs seven different GPU sub-tests, ranging from face detection to FFTs, and then averages out their scores via their geometric mean. As a result Geekbench 4 isn't testing any one workload, but rather is an average of many different basic workloads.
Lastly, we have SiSoftware Sandra, with general compute benchmarks at different precisions.

FFXV results sure look CPU limited to me - why aren't you running at least an 8700 @ 5ghz?Oxford Guy - Thursday, February 7, 2019 - link
They look like GameWorks or something to me but I can't see why anyone cares about FF anyway. I hurt my face smirking when I saw the footage from that benchmark. Those hairstyles and that car... and they're going fishing. It was so bad it was Ed Wood territory, only it takes itself seriously.luisfp - Thursday, February 7, 2019 - link
People don't forget that Vega GPUs have the memory beside the GPU core, therefore making it more hot that normal GPUs out there. That has a lot to do with how hot it seems to be, the temperature tends to raise more due to memory temps in same area.just4U - Thursday, February 7, 2019 - link
True enough but owners of the 56/64 have found many work arounds to such things as the cards have not needed as much power as they push out. My cards (56s) use 220W of power per card They never go over 65c in any situation and usually sit in the high 50s to low 60s. with their undervolts.luisfp - Thursday, February 7, 2019 - link

Better than a 64 in all situations and comparable to a 1080ti in all situations with only 5-6% performance hits against the 2080 which is costing 50-100 more here in Canada (according to pre-order sales) Yep, Im sold.ballsystemlord - Thursday, February 7, 2019 - link
Your favorite spelling/grammar guy is here. (AT Audience: Boo!)"Faced with a less hostile pricing environment than many were first expecting, AMD has decided to bring Vega 20 to consumers after all, duel with NVIDIA one of these higher price points."
Missing words (and & at):
"Faced with a less hostile pricing environment than many were first expecting, AMD has decided to bring Vega 20 to consumers after all, and duel with NVIDIA at one of these higher price points."
"Which is to say that there's have been no further developments as far as AMD's primitive shaders are concerned."
Verb tense problem:
"Which is to say that there's been no further developments as far as AMD's primitive shaders are concerned."
Thanks for the review!
I read the whole thing.
The F@H results for Vega are higher than I predicted (Which is a good thing!).

I was joking. Some site content creators call people like me "The spelling and grammar trolls".I can never really be certain, so I try to be a little funny in hopes that no body will take my corrections as "troll" actions.
I don't know how you guys feel, but you've always taken mine and others corrections into consideration.
