How AMD is Fighting NVIDIA with RDNA3 – Chiplet Engineering Explained

Sponsor: Thermaltake Core P3 Pro on Amazon
We’re talking with one of AMD’s leading engineers (Sam Naffziger) about RDNA3 GPU design and challenges with going to chiplets for a GPU. We only had about 15 minutes to cover the highlights, so we focused mostly on the differences between chiplets on Zen CPUs and RDNA3 GPUs. This gives a unique insight into the architecture of AMD’s next attempt at another “Zen moment,” this time with its graphics division.
