Effectively, now we’ve seen all of it. You could have heard of twin GPU setups up to now, however combining AMD and Nvidia in the identical system? Even for those who’re utilizing two of the most effective graphics playing cards, that’s all the time going to be difficult. Nevertheless, it’s now been finished and benchmarked, and the outcomes are shockingly good — with a number of main caveats.
QuasarZone took an opportunity on this, because the outlet itself admits, “loopy concept,” and it turned out higher than most of us might need anticipated. The publication mixed an Nvidia RTX 4090 with an RX 6600 to attempt to use each GPUs directly. The aim wasn’t simply to see whether or not it was attainable for it to work however fairly to strive the mixed energy of Nvidia’s DLSS 3 and AMD’s Fluid Movement Frames (AFMF). The latter remains to be within the technical preview stage.
As anticipated, operating such a combo of GPUs is not any simple feat, so the setup course of sounds fairly daunting. After putting in the RTX 4090 and the RX 6600 within the check system (which additionally included an AMD Ryzen 9 7950X3D), the tester needed to set up drivers for each GPUs, together with a beta driver for the AMD card to entry AFMF. The RX 6600 was set as the first GPU, whereas the RTX 4090 took on the rendering position. On this situation, the AMD card controls the show output, and the Nvidia GPU renders the sport.
It’s price noting that DLSS 3 and AFMF work in another way. Nvidia’s DLSS 3 will increase body charges by including generated photos between rendered frames. It’s solely accessible on RTX 40 GPUs and must be supported by the sport to work. AFMF, however, is enabled on the driving force aspect, that means it ought to work with all DX11 and DX12 video games. Establishing the GPUs on this means allowed video games to first undergo Nvidia’s DLSS 3 after which hit AMD’s Fluid Movement Frames earlier than reaching the show.
Now, for the juicy components — QuasarZone was capable of obtain an enormous improve in frames per second (fps) in among the most demanding video games, together with Cyberpunk 2077, Name of Obligation: Fashionable Warfare III, Ratch & Clank: Rift Aside, and Starfield. Starfield doesn’t even assist DLSS Body Era but, so the outcomes don’t embrace it.
QuasarZone was capable of just about triple the native efficiency in Cyberpunk 2077reaching as much as 209 fps with DLSS Body Era and AFMF each enabled. That’s a 291% improve over native fps. Related beneficial properties could be seen throughout all the opposite titles, which is a formidable efficiency for 2 GPUs that ought to have by no means ended up in the identical PC.
Does this imply that this would be the new dream setup for fans, one thing like what the twin Titan GPU was up to now? No probability. Pairing two GPUs from completely different distributors, full with drivers, is unsustainable and might result in main instability, crashes, blue screens, and what have you ever. This was a enjoyable experiment, and clearly, it labored, but it surely most likely wouldn’t work for too lengthy.
