Memory bandwidth in w6900x is roughly 500gb/s. In 3090 it's more than 900gb/s. Yet, 3090 performs like 5500M(which is laughable). In M1 Max bandwidth is 400gb/s

- MobiusHorizons 5y agoThe difference is that with the w6900x, the memory bandwidth is not used to transfer data between the dGPU and main memory. That happens over PCIe instead.
