However, even with the v-sync limitation, the results are something of a revelation with the R9 390. We've reached out to Oxide about this, but in the meantime, to make a meaningful comparison, we re-benched all of our AMD tests with v-sync enabled to match the presentation we were getting from DX12.Ĭore i7 4790K (4.4GHz, Four Cores, Eight Threads)Ĭore i3 4130 (3.4GHz, Two Cores, Four Threads) Results will also take a very slight hit as in many places the GPU will be waiting for the next display refresh before it draws the next frame. So this limits top-end performance on the R9 390 to 60fps, though in practise it rarely reaches this limit. One thing that became clear after our testing as we studied video captures is that the AMD card would only run at DX12 with v-sync enabled (all the other benches are run with v-sync off - standard benchmarking practise). So in looking at the average scores in the table below, you can see that the i7 is pretty heavily GPU-bound. On the i7, that's around 78.5fps and on the i3 that drops down to 41.5fps. We ran the game on medium settings with no MSAA, selections we made in order to move CPU utilisation to the forefront and to give DX12 an opportunity to shine.Ĭuriously, the Ashes of the Singularity benchmark also has a DX12 benchmark purely for the CPU - a frame-rate average that completely eliminates the GPU from contention, giving an idea of theoretical top-end performance. We went for the Radeon R9 390 and the GTX 970 as our graphics hardware of choice, paired with the Core i7 4790K (up to 4.4GHz with four cores and eight threads) and a somewhat less capable Core i3 4130 - a dual-core, quad-thread CPU running at 3.4GHz. The key advantages of DX12 we'll see in the first wave of games are primarily in the CPU area - so we wanted to test two equivalent graphics cards from AMD and Nvidia on two different consumer-level CPUs. Our own testing methodology is fairly straightforward. This has provoked a polite exchange of words highlighting a difference in opinion between the GPU vendor and the developer, and Nvidia has even distributed its own 'reviewer's guide' for the benchmark to the press. Our results paint quite a picture: on the one hand, we see some phenomenal gains on the AMD side, while on the other, Nvidia performance looks somewhat underwhelming. The embargo lifts today on the first DirectX 12 gaming benchmark - a scripted series of sequences taken from Oxide's forthcoming Ashes of the Singularity.
