Uh, no. This headline is wrong. It's FP32 unlocked from being halved, not 16 bit ops. And to be clear, over the last week I've looked many places and I've not seen any reports of this unlock being applied to any 3xxx card except the 3090/3090ti series. Even if it might apply more generally in theory.

It's the FP/BF16 FMA to FP32 instructions.

And also it does work on most 3000 series cards as they all run the same GA102 booter that's vulnerable :-) There are some reports of cards with weird vbios layouts having issues but i'll try to get that fixed

The repo has fp16 numbers.

Also this one for 4070s shows that its for fp8 as well:

The repo has a lot of reports of people applying it to other 3xxx card, see https://github.com/Zagitta/gpu-unlock/issues

There's at least 3080 Ti, 3070 Ti, 3070, 3060
