Am I reading those Cuda core projections right?

GA102 to AD102 increased by about 80%, but the jump from Ad102 to GB202 is only slightly above 30%, aside from no large gains going to 3nm?

Might not turn out that impressive after all.

Its expected to be like Ampere, Ampere was 17% increase in SMs (rtx 3090ti vs rtx Titan) but the SM itself was improved such that they yielded about 33% improvement per SM in 'raster' and massive improvements in occupency for RT workloads. So 3090ti ended up 46% faster in 'raster' vs rtx Titan.

The TPC and GPC of Blackwell are rumored to be overhauled with a more hesitant rumor about the SM also being improved.
