A Tale Of Two Architectures
The FPS Review have been hard at work pumping out video card reviews, including one which covers something we haven’t seen much of. They tested the compute performance of the RTX 3090 Ti and Radeon RX 6950 XT, the two flagship cards from NVIDIA and AMD respectively. The tests should give you an idea what to expect if you put this expensive silicon to work.
The tests covered synthetic benchmarks including Geekbench, Blender, Luxmark and SPECviewperf 2020 v3.0 as well as a handful of others. There was a clear winner between the two cards which was obvious right from the start. The first few synthetic benchmarks had NVIDIA’s RTX 3090 Ti almost doubling the performance of the RX 6950 XT. Once they started trying test workloads in programs like SPECviewperf the performance disparity became far more reasonable, but NVIDIA’s card still won every single test.
If you are more interested in the gaming performance these two cards are capable of, then this review is where to go. To start they overclocked both cards as far as they could, for the RTX 3090 Ti that resulted in a GPU running an average of 2160MHz and memory of 23GHz. The RX 6950 XT was massaged up to 2800MHz on the GPU and memory of 18.8GHz, which makes things interesting when it comes to looking at the impact of memory bandwidth versus GPU clock.
The results of those tests, barring ray tracing, were much different than with the compute review as the cards trade places for the top spot. Some games preferred AMD, others liked NVIDIA but either way overclocking these cards had a noticeable effect.
