With 24GB of fast 18Gbps GDDR6 memory.
Basically, the bigger the memory bus, the more performance you’ll get. And this time the upcoming Navi 31 will feature a 384-bit Memory Bus (rumored).
Taken from Videocardz … In a response to 3DCenter.org’s Navi 3X spec update from last week, Greymon55 pointed out that the information on RDNA3 GPU memory bus is incorrect. As it is now, it appears that Navi 31 would feature 384-bit bus (not 256-bit) whereas Navi 32 would get 256-bit (not 192-bit).
That’s a major development and an important memory bandwidth boost for AMD series. Assuming that each of those cards ships with at least 18 Gbps GDDR6 memory, this would give 864 GB/s for Navi 31 alone, and that’s not even accounting for Infinity Cache. The Navi 32 memory would offer 576 GB/s bandwidth, while Navi 33 would go unchanged at 128-bit and 288 GB/s.

As @kopite7kimi pointed out, old info from last Oct is outdated 😉

The Navi 31 GPU was previously rumored to feature a 256-bit memory bus and up to 32 GB of capacity. The 384-bit configuration increases the bandwidth as well as reduces the number of memory modules, which can lead to cheaper product and less demanding cooling capacity.
