News Leaker discusses Nvidia Blackwell memory configurations — suggests GB202 with 512-bit, GB203 with 256-bit, and GB205 with 192-bit

Nvidia is reportedly keeping memory bus-widths the same on at least two of its next-generation RTX 50-series GPUs, GB203 and GB205. GB203 will supposedly have a 256-bit interface and GB205 will have a 192-bit memory bus width, according to leaker Kopite7kimi.

This story seems disjointed. 512-bit is mentioned in the headline and then nowhere else.

A fun move might be 512-bit 5090 with 32 GB, then the next generation they dial it back to 384-bit, but with an increase to 36 GB since 24 Gb GDDR7 will be ready by then.

The 512-bit rumor contradicts previous rumors of 384-bit and 24 GB. Nvidia could be putting out misleading info behind the scenes again to trick leakers.

Exactly.. they just care about the clicks

<blockquote> The use of 24Gb (3GB) devices would mean the GB203 could support up to 24GB and GB205 could support up to 18GB, with GB206/207 supporting 12GB. That would go a long way towards alleviating concerns about VRAM capacity, even if the memory bus widths stay the same.</blockquote>

Or it could use 16Gb(2GB) then it would be 16GB, 12GB and 8GB and nothing much would have changed with regards to alleviating concerns around VRAM capacity.

personally i think i might go big big next gen love my AMD cards but if the 5090 is going to be a monster monster then i may try to swap out of the rat race go the 5090 and sit on it for 2 gens //
providing im happy with the cable config im still worried about the current plug con fig and skeptical about the new one ..
That said i burnt out ( super upset about it ) one of the plugs on my 7900xtx the other day using the pcie 6x2 plug so !!
