It's been four years since AMD launched RDNA, the successor to the venerable GCN graphics architecture. We take a look through the tech and numbers to see...
Then they should have made a fatter GCD 250mm^2 vs 150mm^2 with 140 or something CU’s, and added 3d stacked cache to feed it on the MCDs. They might have even had a plan to but flaked out. Beat 4090 on raster, and compete with 4080 on RT. I was hoping RDNA4 would do just that, but the rumors of AMD only doing mainstream for RDNA4 seems the opposite.
