INT4 → INT32 tensor rate
Unsigned INT4 multiply with an INT32 accumulator, the aggressive quantisation path.
How this path is measured
Register-resident MMA issue rate at the card's stock power cap, 20,000 iterations and three timed repetitions, with every output cell checked per state.
What the unlock changes on this path
4 rows over 4 cards. 0 improved by more than 5%, 4 did not; the largest gain is GeForce RTX 4070 Ti SUPER at 1.00×.
| Mode | Stock | Unlocked | Gain | Card |
|---|---|---|---|---|
u4/s32 | 754.8 | 754.7 TOP/s | 1.00× | GeForce RTX 4070 Ti SUPER |
u4/s32 | 368.7 | 368.7 TOP/s | 1.00× | GeForce RTX 4060 Ti 16GB |
u4/s32 | 673.9 | 672.4 TOP/s | 1.00× | GeForce RTX 4070 Ti |
u4/s32 | 527.2 | 525.7 TOP/s | 1.00× | GeForce RTX 4070 (AD103) |
Reading the numbers
A 1.00× row is not a failed unlock. It says that particular path was never rate-limited, so the override had nothing to restore. If you benchmark your own card and see 1.00× on the mode you care about, the unlock may well have applied correctly and simply does not help that workload.
