GPU Unlock mod boosts AI compute on RTX 30 GPUs by up to 2x
An open-source project called GPU Unlock by developer Zagitta removes the FP16/BF16 Tensor Core issue-rate limit on consumer Nvidia Ampere cards without driver patches or VBIOS flashing. Tests show RTX 3080 Ti BF16 throughput rising from 71.59 to 113.98 TFLOPS and ComfyUI gains of 56–58%.
- Supports GA102, GA103, GA104 and GA106 — most of the RTX 30 lineup
- RTX 3080 Ti: BF16 up from 71.59 to 113.98 TFLOPS at 315W
- ComfyUI gains up to 58.6% on BF16, INT8 barely changes
- No proven gains in gaming or DLSS performance
