Speculation and Rumors: Nvidia Blackwell ...

Not necessarily. We don't know if Blackwell will have the same boost behavior.

If it will and this rumor is true though then yeah, sustained boost clocks should be around 3.6Ghz.
 
How did you get to 3.6? The 4090 tops out at around 2.7.
More like 2.9.

FE specifically does 2.7, yes:

Yeah let’s try to avoid using souped up AIB numbers when speculating on upcoming hardware.

And its base is 2.235 GHz. Applying a similar ratio for a base of 2.9 GHz I get 3.5 rather than 3.6, but still much higher than Ada.

With the obvious caveat that two huge assumptions are being made there.

Ah that makes sense. I mistakenly used 2.32 and not 2.23 for base. Either way there’s no guarantee the boost algo works off percentages that way and certainly no guarantee Blackwell uses the same ratios. Anything around 3.5 will be pretty impressive.

These two cards have the exact same base clock so there's nothing "souped up" there aside from power limit.
Lovelace seem to top out at ~2.9 across all chips really. You need to do w/c or LHC to push it higher.
 
Edit - I can see boost clock for the highest clocking GPUs of this arch, that's a reasonable target. That the highest tier consumer part would also target the highest tier boost clock is questionable, those parts are usually power limited and I see every reason to assume that's the case here.
