By using a kernel module that applies specific speed selectors before the driver binds, the tool doubles the instruction issuing speed for FP/BF16 FMA operations on GA102, GA103, GA104, and GA106 chips without requiring vBIOS flashing or hardware mods. Users report up to an 80% boost in compute capabilities, with the RTX 3090 Ti seeing BF16 performance jump from 87.5 TFLOPs to 157 TFLOPs.\n\nIn practical AI LLM workloads, the unlock delivers a 33-36% faster prefill speed and reduces time-to-first-token latency by 25%, though decode performance remains unchanged. One user reportedly achieved 381 tokens per second on a Qwen3.8-27B model using an RTX 3090, a significant increase from the baseline 82 TPS. The tool currently supports only Linux, with Windows support not yet available.\n\nThis performance uplift has triggered a sharp rise in the used market. The RTX 3090 24 GB, previously around $1,000, has climbed past $2,000, while the RTX 3090 Ti approaches $3,000. RTX 3080 models are now selling for $900-$1,100 on eBay. While the tool makes older cards viable for AI inference and fine-tuning, it is making them less accessible for gamers due to the price surge driven by AI demand.","keyPoints":["Zagita tool doubles BF16/FP16 compute on RTX 30/40 GPUs via Linux kernel module.","RTX 3090 Ti BF16 performance increases from 87.5 TFLOPs to 157 TFLOPs.","Used RTX 3090 prices have surged past $2,000 due to increased AI demand."],"whyItMatters":"This tool significantly extends the lifespan of older NVIDIA GPUs for AI tasks, making high-performance inference more accessible.
