We will mainly be testing the W5700 against the WX 7100, WX 8200 and NVIDIA Quadro RTX 4000, but we thought it would be good to look at the full Quadro RTX range as a background.
The Quadro RTX 4000 is a single-width card, whilst the RTX 5000 and 6000 take up two expansion slots like the W5700.
You could be deceived into thinking the RTX 4000 has some great similarities to the W5700, since both have 36 compute units and 2,304 cores. But the differing architectures mean that you can't make a direct comparison. In the past, AMD has needed more Stream Processors to provide similar performance to a given number of CUDA cores, and the RTX 4000 also runs its cores at a considerably lower clock.
The RTX 4000 also only offers 416GB/sec memory bandwidth from its GDDR6 memory, due to a slightly lower clock speed compared to the W5700.
Either way, with the RTX 4000 costing close to £1,000 inc VAT, and the R5700 costing $799, if the latter can provide competitive performance with the same level of professional support, the RTX 4000 will have some questions to answer.
