AMD Blackwell has GB202 GPU Can Have 384-got GDDR7

There will not be a 512-injured storage capacity connector for the graphics cards manufactured by flagship product, the Blackwell GB202 GPU,  Instead, it will have 384-bit GDDR7

The well-known hardware leaker kopite7kimi made a mistake in their own forecast, which said that Nvidia’s future-oriented flagship graphics processor unit would have a 512-bit memory interface if it was based on the Blackwell architecture

It seems like Nvidia’s GPU processing unit, and this is being referred to asGB202 GPU, is going to keep to make use of a 384-bit memory bus, but it will switch to using GDDR7 type of memory instead

They responded affirmatively when requested whether this mean a 384-bit storage capacity interface for the GB202 GPU, and they clarified that the component would also utilize GDDR7 in their response

Utilizing GDDR7 memory over a 384-bit interface would also bring advantages in addition to those provided by utilizing a 512-bit bus, which would allow Nvidia to dramatically boost the amount of performance given to its next-generation powerhouse graphics cards

If Nvidia decides to employ Micron’s 32 GT/s 16 Gb ICs, then the RTX 5090 will have 1.536 TB/s of memory bandwidth. This is an increase over the 1.008 TB/s that the RTX 4090, which is now the most powerful graphics card on the market, receives
