NVIDIA GB202 "Blackwell" Die Exposed, Shows the Massive 24,576 CUDA Core Configuration

It always bums me out when we never get a fully enabled big die part. Even if it doesnt make sense as a product at the time, its cool to pickup years down the line, and cool to compare fully enabled big die parts on a gen to gen basis.
I forgot that AD102 was actually smaller than GA102.

AD102 is only a little smaller than GA102: 609 mm^2 vs 628 mm^2. The true behemoths are TU102 and GB202. TU102 actually has more area dedicated to the SMXs than GB202 as the latter has a wider bus and massive L2 cache.

Enabling more cores could create a power budget issue, they are moreorless at the max of the connector already.

The no of cores enabled on 4090: 16384/18432 = 88.89%
The no of cores enabled on 5090: 21760 / 24576 = 88.54%

There's a huge gap in the new line-up for a 5080 TI with 20/24Gb and ~15000 cores. but it wouldn't surprise me if we get another die for this, if they decide to release such a model at all.
