Which GPU specs should you use to measure performance? This question becomes moot since benchmarks should be your north star when evaluating multiple GPUs. That said, VRAM has been a major point of discussion lately, hence it’s important to highlight why it isn’t a make-or-break GPU specification, and why there’s a better spec that we should be focusing on. I’ve decided to use memory bandwidth as one of the most important parameters to determine GPU performance, for both gaming and non-gaming workloads.
