Nvidia's next-gen B300 GPUs have 1,400W TDP, deliver 50% more AI horsepower: Report

Nvidia's rollout of its first-gen Blackwell B200-series processors faced a roadblock due to yield-killing issues, and several unconfirmed reports of overheating servers have also emerged. However, as reported by SemiAnalysis, it looks like Nvidia's second-gen Blackwell B300-series processors are just around the corner. They will not only feature increased memory capacity but also offer 50% higher performance with just 200W of additional TDP. 

Nvidia's B300-series processors feature a significantly tweaked design that will still be made on TSMC's 4NP fabrication process (a 4nm-class node with enhanced performance tuned for Nvidia), but the report claims they will offer 50% more compute performance than the B200-series processors. That performance increase comes at the cost of a massive 1,400W TDP, just 200W higher than the GB200. The B300 will become available roughly half a year after the B200, SemiAnalysis claims.

    How come they aren't using the N3 process instead?

    Sounds largely credible.
    However, this is veeeeeeeery dangerous for NVidia, this is like Marketing Sin #0, NEVER announce the superior nextgen product until you've exhausted the market for present generation.
    This could cause a huge wave of cancellations for B200.*
    Wait and see.

    *unless that's actually what NVidia would like to happen, say if they can't actually deliver on promised volumes.

    Given the changes to the overall deployment design I think you might be right on here.
