Firmware hack unlocks Nvidia GPUs' throttled AI performance

Original: Nvidia RTX 20, 30, and 40-series GPUs hacked to remove a half-speed AI throttle — firmware exploit doubles RTX 4090's peak tensor rate, lifts RTX 3090 Ti matrix math up to 80%

A newly discovered firmware exploit disables an artificial half-speed AI throttle on Nvidia's RTX 20, 30, and 40-series graphics cards. Tests reportedly show the RTX 4090's peak tensor performance roughly doubling, while the RTX 3090 Ti gains up to 80% in matrix math throughput. The finding is drawing attention because it suggests Nvidia may have limited AI workloads in software, with potential gains for local machine learning users.

Why now: Free AI performance gains on widely owned consumer GPUs are highly relevant to the booming local AI and machine learning community
