Still not sure there will be a B770. There are talks of a 2025 launch for Celestial, which may mean skipping Battlemage and pushing a full line up of C cards using Intel 18A.
Since we have seen no hints of Battlemage mobile or anything smaller in the line up, it does raise a lot of questions. (No Battlemage Pro cards either)
Battlemage cores look to be slightly larger, even after the shrink from N6 to N5. (Unless the B580 is not a fully enabled chip)
A 30/32 Xe core Battlemage would still be around the promised RTX 4070 like performance, which if sold cheap enough would still have a decent market impact. With $500-550 being the floor for that class of card, if they came in at $500, that would be quite good today. If they priced it like they did the B580, then it would be like $400, and could get them more good will.
I agree a 56-64 core Battlemage is not an economic winner.
Hard data on 18A with or without power Via vs TSMC N5 (or smaller) would make the fortune telling a little easier when it comes to Celestial. Tom's article points out rumors that Intel may have the clock speed advantage over TSMC N2, while TSMC retains higher density.
But if the news today about Nvidia looking at 18A for gaming GPUs is any indication, they are somewhat competitive in that regard.
Edit- Raw math, bad to use, shows about a 70% density increase from N5 to 18A (or even a little better with Samsung or TSMC), which would put a 400mm2 die like was used for the A770 at 54 or so Xe cores. So your 56 Xe core idea isn't too far fetched with a node shrink.
