That leads to some interesting conclusions. Nvidia’s GTX 900-series graphics cards perform worse in DX12 than in DX11, and that’s with async compute features disabled. That’s not the case with the GTX 1070 (or the GTX 1080); in fact, once Pascal GPUs surpass graphics bottlenecks, they can achieve a decent leap in performance in DX12, as shown in the 1440p/high and 1080/high results. I’m extremely curious to see if Oxide decides to lift the hard lock on async compute capabilities for GTX 10-series cards, and if so, whether the Pascal GPU’s new async tricks lead to more consistent DX12 performance gains.
As it stands today, the GTX 1070 again triumphs over the Titan X here, and in fact, in DX11 it’s hands-down the second-most-powerful card after the GTX 1080. But the really intriguing thing is how much of an advantage AMD’s dedicated async compute engine hardware provides in DirectX 12. Radeon cards see sizable performance increases across the board in DX12, as the ACE hardware helps distribute workloads to avoid the GPU bottlenecking seen in Nvidia’s cards. In DirectX 12, the Fury X handily beats the GTX 1070, and the Fury and R9 390X both hang awfully close.
SteamVR Performance Test
A lot of the Pascal GPU’s potential performance benefits revolve around VR and developer adoption of Simultaneous Multi-Projection. Unfortunately, those heady days still fit firmly in the future despite the recent launches of the Oculus Rift and HTC Vive.
Granular VR benchmark tools coming from Crytek and Basemark haven’t hit the streets, and no released VR games support the GTX 1070’s new software features yet. There’s no way to quantify the GTX 1070’s potential VR performance increase over the competition except for the SteamVR benchmark, which is better for determining whether your rig is capable of VR at all than direct head-to-head GPU comparisons.
Alas. The GTX 1070 doesn’t quite crank things to 11 like the GTX 1080 does, but it still matches the Titan X’s overall score, and comes out comfortably ahead of the best AMD has to offer.
