I am surprised they are going with a 512-bit memory bus, I was under the impression such wide buses weren’t particularly cost effective for consumer products.
If you want a lot of VRAM then it makes sense to go with a phat bus. The 5090 has a 512 bit bus so maybe AMD is going to try to compete with Nvidias next flagship? AI needs a lot of bandwidth as well.
That said I’d really like to see more 384 bit cards. It’s enough bandwidth for 4k, lets you get a lot of VRAM without crazy dense modules, but you’re not wasting so much silicon space on the bus. Currently it’s the 5090 with a 512 bit bus, or a 5080/9070 all the way down with a 256 bit bus.
Makes sense. Although I not sure if the 5090 qualifies as a consumer card. HEDT class seems like a better fit, something similar to Threadripper.
