An overclocker using an extreme liquid nitrogen-cooled Nvidia RTX 5090 has broken the world record in 3DMark's Port Royal benchmark, pushing ray-tracing performance benchmarking to new heights. The feat highlights just how far enthusiast-grade cooling and component binning can extend the ceiling of Nvidia's flagship consumer GPU beyond its stock capabilities, offering a glimpse of the card's theoretical maximum performance under extreme conditions rather than what typical buyers will experience.

Achieving the record required specialised hardware costing upwards of $5,000, including cryogenic cooling equipment to keep the RTX 5090 running far colder than air or standard liquid cooling would allow, enabling drastically higher clock speeds. Such records are typically achieved by dedicated overclocking enthusiasts and hardware modders rather than everyday users, and while not representative of real-world gaming performance, they serve as a benchmark for the outer limits of current GPU architecture.
