So, he says that it goes from 1x to 1.83x when going from 1 to 2 GPUs.

What is unclear here O_O

Yeah my math was terribly wrong. I am not even sure how I did that without realizing it. He got his stat from the utilization.

51% (CPU-bound), medium is 71.9% utilization (less CPU-bound) and heavy batch utilization is 92.3% (not CPU-bound) which is averaged at 71.7% utilization which means you are losing about 20% performance if you consider 92.3% the most utilization you can have. So each card is doing half the 62.5 frame rate at 31.25 fps at only 80% performance, or 37.5 fps at full performance.

That's more impressive mental hulahooping, but there are few actual flaws here:

1) Most utilization you can have is 100% so every part of demonstration was CPU-bound at some point. On both 1080 and rx480s.

2) I am absolutely positive you cannot average out GPU utilization figures.

3) Your numbers don't connect with his stat whatsoever.

Anyhow, I'm surprised that we haven't heard much about Polaris11,but I suppose OEMs have already taken all the chips for the foreseeable future.

About Vega, AMD wil do the same as they did with Polaris - they will preview the architecture against a 1080 4 months before release. I'm worried that it will be a repeat of Fury though, don't think the market is ready for HBM2.

Anyone know packaging costs for HBM?

I was thinking of used/refurb 290x around that price. I may be wrong ofcourse but still, it is old performance.

1. I agree, it's possible, but he said the Heavy batch wasn't CPU bound and was only at 92.3 utilization.

2. Ashes of Singularity averages the frame rate of single, medium, and heavy batches frame rate. He leaves out the frame rate for each batch and just gives the GPU utilization. Either GPU utilization scales to frame rate in a linear fashion or it doesn't. If you think it doesn't, then you agree with my actual opinion.

3. GPU utilization sounds exactly where he is getting the 1.83x number.

"//EDIT: To clarify this, the scaling from 1->2 GPUs in the dual RX 480 test we assembled is 1.83x. The OP was looking only at the lowest draw call rates when asking about the 51%. The single batch GPU utilization is 51% (CPU-bound), medium is 71.9% utilization (less CPU-bound) and heavy batch utilization is 92.3% (not CPU-bound). All together for the entire test, there is 1.83X the performance of a single GPU in what users saw on YouTube. The mGPU subsystem of AOTS is very robust."

Honestly man, since RTG split they have been firing out drivers like crazy, and ontop of that, I think they will take special care with this cards crossfire because it is meant to be the market share card... kind of a gamble but i want something new to tinker with.
Sorry AMD

1. Well, it's mostly GPU-bound, with acceptable margin.

2. It does not average them in naive way, i actually checked it on few results. Either it takes a very weird weighted average or just gives the whole frames/bench duration number (the latter makes most sense for well known reason).

3. No, it sounds like he is explaining that GPU utilization on slide has nothing to do with multi GPU scaling (makes sense, it's very easy to get CPU bottlenecked on stock 5930k in AotS), while commending Oxide (he would not be in Technical Marketing otherwise), and then makes too precise to be ballpark claim on multi GPU scaling in the demo.

P. S. With all that we forgot that AMD's slide also claimed better efficiency for dual rx480s. Now that's one fun claim that can backfire for AMD, heh.

2. Yes, that's another reason why I think his number cannot be applied to the averaged frame rate to figure out where the 480 sits.

3. I agree that there's bottlenecking there which adds an additional issue of trying to figure out the frame rate of a single GPU. We don't know how much of the lack of utilization is from bottlenecking and how much is the inefficiency of multiGPU.

AMD's slide is promoting explicit multi-adapter, a DX12 feature that Ashes of Singularity supports. It's reliant on game developers to implement it unlike crossfire which is driver side. A multi-GPU 390X won't be treated any differently than a multi-GPU 480.

I mean, the whole thing is extremely weird. But whatever, it just slightly lowers my expectations down to non-throttling reference 290 level and that's still a god damn good value for $199. We'll see in end of June thumb.gif

Yes but CFX has been terrible since 2015. Its so bad right now that 1 card feels a lot smoother even though fps is lower. I understand games where SLI does not work but Witcher 3 for example SLI scales perfectly and does not stutter.
