RTX-5090 problem, the fourth: users complain of missing ROPs.
The bad news about the RTX 5090 just doesn't want to tear down.
Starting with poor availability, which ensure horrendous dealer and street prices, and recurring reports from melting plugs to drivers to the release, which the RTX 5090 initially made, the Nvidia flagship had a turbulent start.
To make matters worse, a chip problem can now also be observed in the Nvidia flagship.
Like the portal TechPowerUp First reported, its test pattern of a Zotac GeForce TX 5090 SOLID has less active ROPS (“Render Output Units”) than it should have.
- It was noticed by the otherwise useful GPU-Z tool. The Custom GPU mentioned showed only 168 active ROPs here-but according to the official Nvidia data sheet, this should be 176.
- Also on the discord server of our colleagues from ComputerBase If an owner of such a Zotac RTX 5090 Solid, in which not all ROPs were also active, reported.
A short tech excursion: Render Output Units are decisive components of the graphic pipeline who are responsible for the final image calculation. They process pixel and deep information, carry out anti-aliasing and write the data in the frame buffer.
The higher the number of ROP, the more pixels per clock cycle can be processed-a direct performance factor, especially with high resolutions and complex scenes. A reduction on 168 units theoretically means a loss of 4.54 percent; The actual loss of performance in synthetic benchmarks can amount to up to 11 percent.

Gothic remake: These 6 things have to change until the release
Assumption: “Small batch with defective chips”
The assumption of TechPowerup that only Zotac-GPUs are affected quickly turned out to be an error. Computer base itself tested the same model and found the correct number of rops.
This only makes the location more complicated: on the X platform, the owner of an RTX 5090, which indicate the same problem. The Custom GPUs concerned are different models of gigabytes, MSI and Manli. Even the Nvidia-owned Founders Edition does not seem to be spared the problem.

There is no statement from NVIDIA at the time of the article publication, so we now have to go to the space of speculation. The leaker, which is considered well informed Megasize For example, thinks that “a small batch of defective chips” was delivered, which are now noticeable.
The worst-case scenario (for NVIDIA) is therefore: Should the eight affected ROPS hardware Being deactivated, it boils down to a larger recall. In this case, Custom partners would be less to look for, since Nvidia rop configurations are predefined; So the problem has slipped through quality control.
It is not yet known whether the RTX 5080 is also affected.
