Blackout at Blackwell, the next: First graphics cards of the RTX-5080 series also have missing ROPS (render output units). This affects all the GPUs of the RTX 50 generation that has been released so far.
- Initially, it had caught the RTX 5090, which in some cases had 168 instead of the correct 176 ROPs.
- Just a short time later, owners of an RTX 5070 Ti, which found the 96 ROPS instead of the promised 96 ROPS, also reported.
In the current case, a user reported on the Nvidia Subreddit with a GPU Z screenshot that lists the technical data of its RTX 5080. Instead of the actual 112 ROPS, only 104 are listed.

This means that exactly eight rops are missing again. This means that the idea of all affected Blackwell chips is deactivated exactly one ROP partition.
Because since the ampere generation, the ROPs have not been directly linked to the memory interface. Instead, they are integrated in the GPCs (Graphics Processing Cluster). Each GPC typically contains two ROP partitions, with each partition comprising eight ROPs.
NVIDIA itself spoke about "0.5 percent affected cases" during the RTX 5090 reports. This information changed in an updated opinionThe VergeNot even after reports on the RTX 5080 and RTX 5070 Ti.
We have identified a rare problem that affects less than 0.5 % of the Geforce RTX 5090 / 5090D, RTX 5080 and 5070 Ti GPUs. These GPUs have a ROP unit less than specified. The average impact on graphics performance is 4 %, while there are no effects on AI and Compute workloads.
Affected customers can contact the graphics card manufacturer for an exchange.
Affected customers should therefore contact the manufacturer themselves in order to arrange an exchange - what in the face ofcould take.
However, the problem should no longer occur with the upcoming RTX 5070, as the Verge report continues. When asked by Ben Berraondo, the Global PR manager of Nvidia GeForce, the production anomaly is now to be remedied.
At this point, the Nvidia employee also assumes that the manufacturer himself only learned about the production problem in the course of the user reports; In a way, the missing ROPs have slipped through quality control.
