INT4 with an INT32 accumulator

The densest quantized path. Like INT8 it was never fuse-gated, so the unlock does nothing here.

How this mode was measured

Register-resident MMA issue rate at a 240 W cap, 20,000 iterations, three timed reps, all 270,336 output cells checked per state

Every card measured on this mode

Mode	Stock	Unlocked	Gain	Card
`u4/s32`	754.81 TOP/s	754.68 TOP/s	1.00×	GeForce RTX 4070 Ti SUPER · 66 SMs

Same card, same driver, same binary. The unlocked figure is the only variable.

Which cards this covers

Only cards with a same-card measurement on this mode appear in the table. A card missing from it has not been measured on this path, which is not the same as failing.
