Article: Predicting AMD and Nvidia GPU Performance

As many of you may have noticed, we've had a profusion of new articles at RWT in the last few months. I have been writing one short article per week, for the last 5 weeks, while still working on several longer pieces (Poulson, z196, cough cough).

I'd like to take this opportunity to remind everyone that we have a front page (yes it's true!), and that we will be updating it regularly.

I hope everyone that enjoys my articles will make it a practice to check the front page regularly (I aim for M/Tu releases, sometime Wednesday), or at least subscribe to our RSS feed : )

Without further ado, here's the deal on this weeks article:

Modern graphics processors are incredibly complex, but understanding their performance is essential, as they become an increasingly important component of computer systems. In this report, we use a set of benchmark results to build accurate performance models for AMD and Nvidia GPUs. We verify that our model can predict performance within roughly 6-8% for many desktop graphics cards and show how Nvidia’s microarchitecture and drivers achieve roughly 2X higher utilization than AMD’s VLIW5 design.

As always, enjoy and we welcome and encourage comments and discussion.
