RTX 5090 owners have been complaining online for over a week that some cards shipped with fewer ROPs, AKA render/raster output units than they should have. The RTX 5090 review units supposedly have 176 ROPs enabled,

The launch of Nvidia's RTX 50-series hasn't gone well so far, and it seems that things aren't about to improve anytime soon.

“We have identified a rare issue affecting less than 0.5% (half a percent) of GeForce RTX 5090 / 5090D and 5070 Ti GPUs, which have one fewer ROP than specified," an Nvidia representative told Tom's Hardware Saturday. "The average graphical performance impact is 4%, with no impact on AI and Compute workloads.”
