AMD RX Vega 64 LC and Radeon VII, have managed to defeat Nvidia’s top-end GeForce RTX hardware, the RTX 2080 and RTX 2080 Ti, in a World War Z GPU benchmark.
In one particular test, which involved the recently released third-person shooter World War Z, AMD dominated proceedings with even the Radeon RX Vega 56 managing to outpace a GeForce RTX 2080. However, there are a number of caveats involved that should be taken into consideration in regard to the very positive results for the red team. Radeon VII was measured offering an eye-popping average rate of 192 FPS compared to the GeForce RTX 2080 Ti’s best effort of 160 FPS.
AMD RX Vega 64 Outperforms NVIDIA RTX 2080 by up to 20% in Vulkan Enabled World War Z
The benchmarks were published by GameGPU and conducted with an overclocked Intel Core i9 9900K at 5.2GHz to eliminate any possible bottlenecking. Let’s start with the most popular resolution out there, 1920×1080, with Vulkan enabled AMD manages to take all top 3 spots, with its Radeon VII, Radeon Vega 64 Liquid Cooled Edition and Radeon Vega 64.
One conclusion that can be drawn from these results is that World War Z is heavily biased against NVIDIA GPUs and since the performance falls back to normal at 4K means that these gains can be mainly attributed to a lower CPU overhead at 1080p and 1440p whereas at 4K the GPUs are the bottleneck. However, that begs the question as to why are NVIDIA’s GPUs falling behind? Well, to be honest, it can’t be said for sure. The most likely case is that since it’s an AMD title, team green didn’t have much access to the game’s code, thereby resulting in reduced optimization for NVIDIA cards.
Secondly, Vulkan has proved time and again that it favors AMD hardware, mainly because (as already mentioned) it is built on top of AMD’s Mantle. Still, I expect NVIDIA to come up with an update or something to at least bridge part of the performance deficit at lower resolutions.
