Thanks for the prompt response, Ross. I also realized that they use lower power but in the meantime the size of the CUDA cores is almost comparable to A5000 (7680 vs 8192). I tested A5000 and they look good. We are getting some quotes from different companies, and DELL is not putting A5000 cards into the compute nodes but L4 (or worse A2).
Cheers,

Hi Ilyas
The L4 GPUs should work fine with AMBER 22 but I haven't had a chance to explicitly benchmark them yet. They are very low power GPUs (just 72W each) so I would expect the performance to pretty poor. You'd probably be much better off with A4500, A5000 or A5500 cards which are available at a discount right now - likely cheaper than the L4. See:
https://www.exxactcorp.com/blog/Molecular-Dynamics/RTX3090-Benchmarks-for-HPC-AMBER22-A100-vs-RTX3080-vs-RTX3070-vs-RTX6000
for performance comparisons.
All the best
Ross

Dear All,
Does anyone have any experience on running the cuda versions of the AMBER 22 software under NVIDIA's L4 GPU cards? I am planning on upgrading my lab's GPU cluster. Thanks in advance.
Best regards,
