Nvidia GeForce global PR director Ben Berraondo tells The Verge:

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. The average graphical performance impact is 4%, with no impact on AI and Compute workloads. Affected consumers can contact the board manufacturer for a replacement. The production anomaly has been corrected.

In the grand scheme of things, that doesn’t sound like a lot of affected GPUs, particularly because there weren’t a lot of 5090s on shelves to begin with, nor was it a huge hit to performance — as those who discovered the missing render units can already attest. But it is the latest in a line of annoyances with Nvidia’s latest pricy cards, including launch driver issues (including some ongoing black screen issues that Nvidia is still investigating) and some melting power connectors.
