AMD RDNA 3-powered Navi 3x GPUs are now rumored to feature an updated memory layout with the flagship offering the same VRAM as NVIDIA's RTX 4090 graphics card.

The rumor is pretty straightforward and comes once again from Greymon55. There have been recent reports from RedGamingTech that AMD's flagship Navi 31 GPU will be equipped with a bigger 384-bit bus interface compared to the previously speculated 256-bit which was valid but only when the previous specifications were being talked about. It looks like the updated specs lowered the core count but increased the overall memory layout that the flagship RDNA 3 GPUs have to offer.
