What is the best datacentre GPUs for hashcat?

[starfish]

The L40S is 350w ( NVIDIA L40S Product Brief ) where as the L40 is 300w ( product-brief-L40.pdf (nvidia.com) - I presume your reply stands but inverse your references between L40 and L40S? The L4 looks to be the original low power one ( PB-11316-001_v01.pdf (nvidia.com) )

FYI: my requirement is highest possible performance, not power consumption.

Regarding

It can only use one GPU at a time

are you referring to if you had them connected with NVlink it could only use one? But if you have multiple GPUs not connected via NVLink it can use them at the same time or can you just not do parallelized processing?

Thank you for taking the time to explain.
