So, you finally managed to get your hands on an RTX 5090 after the paperwork cleared on your second mortgage, only to discover that it’s giving you 10 percent fewer frames in Minecraft than you expected? The problem could be missing ROP hardware, and now CPU-Z can narrow it down for you with its latest update.
To be more specific, CPU-Z could always give you a precise count of Render Output Units (ROP), but now it’ll show a bright purple warning on its web-based validation page if the number of ROPs in your physical card doesn’t match the proper number according to its specifications.
Nvidia’s RTX 5090 should have 176 ROPs and the 5070 Ti should have 96, but some users are finding that their cards are missing eight of them on their cards. That results in measurably reduced performance versus unaffected cards. (Nvidia blames the missing ROP hardware on a manufacturing defect, which is covered under warranty.)
Igor’s Lab lays out the process for spotting whether or not your RTX 50-series card is affected, first shown by user “Doc TB” on Twitter. Run the latest version of CPU-Z, then click the Validate button at the bottom. Enter an email address (a fake one is fine) and click Submit, which will send a configuration file for your hardware to CPU-Z’s validation server and open a web page in your browser with the results.
Scroll down to the Graphics Card (GPU) section of the page, and in the Units row you’ll see your shaders and render units. If the ROP number doesn’t match the correct number according to your card’s manufacturer specifications, you’ll see the alert in purple text (as seen above).
Nvidia acknowledges the missing ROP issue and says that the “anomaly,” which has been corrected on the manufacturing end, only affected 0.5 percent of the initial RTX 5090 and 5070 Ti batches. That’s nice, I suppose, but that’s still hundreds or possibly thousands of people who dropped a lot of money on the latest and greatest card, only to be stuck with a slow and frustrating return-to-manufacturer experience to get the full performance that they paid for.
