Hi All,
I just got my hands on the latest A4500 GPU through Exxact (
https://www.exxactcorp.com <
https://www.exxactcorp.com/>) - this is positioned between the A4000 and A5000 but should have better availability. As expected it's got performance roughly equivalent to the 3070. A little bit slower for small systems but faster for larger systems. For those interested, here's a table comparing performance across GPU types (and attached in case the mail reflector mangles the formatting).
