[gmx-developers] AMD Radio Pro Vega 64 graphics card

[Erik Lindahl]

Hi,

Yes - they should roughly be on par, with the caveat that we do not yet have PME in OpenCL, so for runs where that is relevant cuda wins. We do hope/plan to maintain feature parity between CUDA & OpenCL in the future, though.

However, the power usage difference is a major drawback for AMD if you are thinking of installing many cards...

Cheers,

Erik
