The Test Bench
The same test setup was used for all these benchmarks. Therefore, it is safe to assume that they are all from the same source. Going into the specifics, we see AMD’s Ryzen 9 7950X paired with 32GB of RAM. As for the performance metrics, let us go over them one by one.
CUDA
Starting off with CUDA, which is exclusive to NVIDIA GPUs, the RTX 4080 scores 300728 points. This is a nice 45% improvement as compared to the RTX 3080. Across the board, it remains ahead of the pack because the only real competitor here is the RTX 4090.
VULKAN
Moving over to VULKAN, the RTX 4080 manages to score 289014 points. The RX 7900 XTX showcased here is assumed to be 1.7x faster than the 6900XT. That may not be the final result, but it can give us a rough idea of where RDNA3 stands. Interestingly, the RTX 4080 here loses to the 7900XTX despite being more expensive.
OpenCL
OpenCL sees the RTX 4080 manage to obtain 148838 points, marginally beating the RTX 3090. Interestingly, AMD’s 7900XTX is faster than even the RTX 4090 in this test. As for the RTX 4080, it offers a 7% improvement generation on generation against the RTX 3080. That’s kind of disappointing though the final reviews will tell the complete story.
RTX 4080
The RTX 4080 16GB is packed with 16GB of GDDR6X memory over a 256-bit bus where the effective bandwidth stands at a whopping 720GB/s. Such insane bandwidths can be achieved thanks to the 22.5Gb/s memory which is 20% faster than last-gen. The 4080 16GB is equipped with the state-of-the-art AD103 GPU and 9,728 CUDA Cores for that extra compute performance. To top it off, it consumes just 320W of power.
