Tom's Hardware published GPU Performance Hierarchy: Video Cards Ranked
A quote from the article:
When you want to run games or do high-end creative work like 4K video editing, your graphics card plays the biggest role in determining performance. Get a good GPU, and you can play recent games at smooth frame rates; get a great one and you can enjoy those games at high resolution, with the special effects turned up.GPU Performance Hierarchy: Video Cards Ranked
To help you decide which graphics card you need, we've developed the GPU hierarchy below, which ranks all the current chips from fastest to slowest. For comparison purposes, we've assigned each a score where the fastest card gets 100 and all others are graded relative to it. These numbers are based on the geometric mean fps from our Far Cry 5, Forza Motorsport 7, and Ashes of the Singularity: Escalation benchmarks, giving us a good mix of game genres and APIs.
