What is the best datacentre GPUs for hashcat?

[starfish]

Thanks Chick3nmann - the information from marc1n was getting somewhat contradictory. 

My understanding is as follows, please correct where I am misinformed:

• Hashcat will use as many GPUs as you give it
  
• Hashcat does not benefit from NVLink/NVSwitch
  
• Hashcat does not benefit from Tensor cores
  
• Hashcat does not benefit from RT cores
  
• The number and clock speed of CUDA/FP32 Cores are important to the performance
  

Regarding GPUs (using NVIDIA's definitions for datacentre and workstation)

• The RTX 4090 is the best performing consumer card you have tested.
  
• The RTX 6000 Ada is the best performing workstation card and should be slightly faster than the RTX 4090 due to its increased number of cores (18,176 vs 16,384) and very similar clock speed. 
  
• The L40 is the best performing 'datacentre' card and likely to perform similar to the RTX 6000 Ada.
  

As you note, other factors include card cost and availability of them in the desired server vendor.

You said you did some testing with the L40, do you have any benchmarks?

Many Thanks
