NVidia has quite a long selection of professional GPUs available based on the Ampere generation chips. While this offers users finer gradations in pricing and performance, it can be more confusing than previous generations, especially since they have dropped the “Quadro” branding. My understanding is that one of the main reasons there are so many options is not just the binning of chips, but supply chain issues with the rest of the parts on the board. Unlike gaming cards where a source part can be swapped and a new revision of the card can be produced without much issue, the professional cards that have been certified by software vendors with very precise conditions, need to maintain those exact specifications. So different versions are created using easier to source parts, and certified again, allowing both cards to be produced as separate options. The main additions to the series are the A4500 and the A5500, which fit as expected between the existing A4000, A5000, and A6000 cards. The A4500 which I have been testing, sits nearly dead center between the A4000 and A5000 on all paper specs (cores, memory, teraflops, etc.), while the A5500 nearly matches the A6000 in processing power, but with the same memory limits as the A5000. While these new cards were announced in the spring, I am finally getting the chance to test one out now.
