RTX 5090 cooled with liquid nitrogen smashes the 3DMark Port Royal world record

Overclocker Cmaker has set a new world record on HWBot for 3DMark Port Royal, posting a score of 51,663 — beating the previous record with a build that is as extreme as it is expensive.

The centerpiece is an MSI RTX 5090 32G Lightning Z, a limited-edition card that launched at over $5,000. Cmaker cooled it with liquid nitrogen, pushing the GPU clock to 3,623 MHz — that's 848 MHz above the card's already-high default max of 2,775 MHz. A custom-milled cooling block was fabricated for the GPU, and the rest of the rig keeps pace: an Intel Core i9-14900KF on water cooling, 32 GB of Corsair Vengeance DDR5 also chilled with liquid nitrogen, and a 1,500 W Corsair power supply. The whole thing is surrounded by fans and looks exactly like you'd expect an extreme overclocking rig to look — functional chaos.

For context, a stock RTX 5090 Founders Edition scores around 36,389 in Port Royal, and the already pricey MSI RTX 5090 Suprim SOC managed 38,715. The jump to 51,663 shows just how much headroom liquid nitrogen unlocks when you pair it with the right hardware and the willingness to mill your own cooling solution. Port Royal is a ray-tracing-focused benchmark from UL, and world record runs on HWBot are a long-standing tradition in the extreme overclocking community — a niche but deeply committed corner of PC hardware culture.

The record is fresh, but these things never stay uncontested for long. Someone with an equally unhinged setup will likely take a run at it sooner rather than later.
