RTX3080 LHR vs RTX A4000 for 3D rendering

Hi, someone please help me to select between MSI RTX 3080 GAMING Z TRIO 10G LHR Graphics Card 10GB GDDR6X, PCIE 4.0, and Leadtek NVIDIA RTX A4000 WorkStation Graphic Card 16GB GDDR6 with ECC, PCIE 4. .

Which one gives better performance for rendering, primarily to use with Arnold/ redshift and Houdini simulations. Not looking for any game usage. I can’t find any CUDA info on 3080 LHR card It just says “cores” does that matters?

Thanks
Jk
