NVIDIA Blackwell "GB203" GPU Could Sport 256-bit Memory Interface
Speculative NVIDIA GeForce RTX 50-series "GB20X" GPU memory interface details appeared online late last week—as disclosed by the kopite7kimi social media account. The inside information aficionado—at the time—posited that the "memory interface configuration of GB20x (Blackwell) is not much different from that of AD10x (Ada Lovelace)." It was inferred that Team Green's next flagship gaming GPU (GB202) could debut with a 384-bit memory bus—kopite7kimi had "fantasized" about a potentially monstrous 512-bit spec for the "GeForce RTX 5090." A new batch of follow-up tweets—from earlier today—rips apart last week's insights. The alleged Blackwell GPU gaming lineup includes the following SKUs: GB202, GB203, GB205, GB206, GB207.
Kopite7kimi's revised thoughts point to Team Green's flagship model possessing 192 streaming multiprocessors and a 512-bit memory bus. VideoCardz decided to interact with the reliable tipster—their queries were answered promptly: "According to kopite7kimi, there's a possibility that the second-in-line GPU, named GB203, could sport half of that core count. Now the new information is that GB203 might stick to 256-bit memory bus, which would make it half of GB202 in its entirety. What this also means is that there would be no GB20x GPU with 384-bit bus." Additional speculation has NVIDIA selecting a 192-bit bus for the GB205 SKU (AKA GeForce RTX 5070). The GeForce RTX 50-series is expected to arrive later this year—industry experts are already whispering about HPC-oriented Blackwell GPUs being unveiled at next week's GTC 2024 event. A formal gaming family announcement could arrive many months later.

NVIDIA Blackwell "GB203" GPU Could Sport 256-bit Memory Interface?:cool::confused::kookoo:
I think should be:NVIDIA Blackwell "GB203" GPU Could Support 256-bit Memory Interface:peace:
As for Sport vs support the context in which it used fits as its saying that is likely what gpu is gonna be vs its possible to support xxx.
The title is fine.
Nvidia is predictable, most already knew.
lets hope Nvidia keeps it reasonable $999/1999 5080/90 /w 12032/22016 cudas. But i can't see 5080 leading to 4090 in ratser with this spec. 25% faster memory and 25% more shaders spells a very weak 80 class gen on gen improvement. In RT RT is different but who cares.
But knowing that Nvidia made a mistake with 1080ti pricing it 699, 2080 ti correction to $1199, then again 3080 $699, 4080 $1199, who knows. Can they perhaps go for a 699 5070 256 bit. In 2025 a 12 GB 192 bit 5070 doesn't make any sense.
Double the CUs in GB202 seems insane. Can't wait to see the price. :D
