Our third and final interview featuring Scott Wasson, current AMD RTG team member and former EIC of Tech Report, has just gone live with information on GPU architecture. This video focuses more on a handful of reader and viewer questions, pooled largely from our Patreon backer discord, with the big item being “GPU IPC.” Patreon backer “Streetguru” submitted the question, asking why a ~1300~1400MHz RX 480 could perform comparably to an ~1800MHz GTX 1060 card. It’s a good question – it’s easy to say “architecture,” but to learn more about the why aspect, we turned to Wasson.
The main event starts at 1:04, with some follow-up questions scattered throughout Wasson’s explanation. We talk about pipeline stage length and its impact on performance, wider versus narrower machines with frequencies that match, and voltage “spent” on each stage.
We’ll leave this content piece primarily to video, as Wasson does a good job to convey the information quickly.
1:04 – How does “GPU IPC” work?
13:08 – When it comes to game optimization with GPUs, does the Radeon team provide support to developers?
17:00 – Why not just do AVG/Min/Max for framerates?
