AMD Graphics Driver Gets "More New Stuff" For Linux 6.9: Continued RDNA4 Enablement

Because recent lithography improvements have only yielded relatively modest improvements in density, esp sram cells have barely shrunk, which is bad news for games, which benefit greatly from larger caches. For this reason the 4090 die is already mostly sram by area. They cant just increase the die size because of reticle and yeild issues

While true the cost for large dies and many chiplet is both limited to what you can sell to gamers. Performance penalty (interconnect) from chiplets and packaging cost are already a big bump in their cost effectiveness.

If your not constrained to low cost (server, HPC) then of course chiplets can scale much better.
