gpu-unlock open-source tool removes GeForce Tensor Core cap, up to 2× BF16 throughput on RTX 20/30/40 cards
Original title: Your GeForce runs AI at half speed. This fixes it for 20/30/40 series cards. Up to 2× FP16 / BF16 / TF32 tensor throughput
The open-source Linux kernel module gpu-unlock removes NVIDIA's half-speed cap on GeForce Tensor Cores for FP16/BF16/TF32 math with FP32 accumulation at boot, before the stock driver loads (https://github.com/zagitta/gpu-unlock). Dense GEMM gains 65–100% on cards from the RTX 3060 to RTX 4090; real workloads see +25–55% LLM prefill, +25–50% BF16 fine-tuning, and +30–55% image generation, with bit-identical outputs. RTX 50 is unsupported, Linux only, and the unlock resets on laptops if the dGPU powers down.
The repo includes concrete per-card benchmarks, supported GPU lists, and a technical explanation, letting readers gauge how much their own GPU workloads would gain.
