Use TechPowerUp GPU-Z with the official graphics driver installed. Open the Graphics Card tab, read the first number in ROPs/TMUs, and compare it with the specification for your exact GPU and form factor. Do not compare a laptop GPU with a desktop specification, and do not treat a driverless or database-only reading as proof of a hardware fault.
Why check for missing ROPs?
ROPs—short for Raster Operations Pipelines or Render Output Units—handle late-stage pixel work such as blending, antialiasing, render-to-texture operations, and writing final pixels to the framebuffer. They are different from CUDA cores, shader units, and texture-mapping units.

GPU-Z, not CPU-Z
The correct utility for this check is TechPowerUp GPU-Z. GPU-Z can read the active configuration through NVIDIA’s driver interface. Without a driver, it may display an internal database value instead.
CPU-Z is primarily a processor, motherboard, memory, and system-information utility. It is not the preferred tool for checking the live ROP count. NVIDIA’s own support procedure also uses GPU-Z when collecting graphics-card information and saving a VBIOS copy.
How to check ROPs in Windows
- Identify the exact GPU. Record the complete name, such as GeForce RTX 5090, RTX 5090D, or RTX 5070 Ti. Note whether it is a desktop card or laptop GPU, plus the board partner and SKU if available.
- Install the official NVIDIA driver. Reboot after installation. This matters because GPU-Z may show a fallback value until the driver is active.
- Download GPU-Z from the official TechPowerUp download page. The portable version is suitable; avoid unofficial mirrors where possible.
- Launch GPU-Z and remain on the default Graphics Card tab. Confirm that it identifies the intended discrete GPU rather than integrated graphics or another adapter.
- Read ROPs/TMUs. The first number is the ROP count and the second is the texture-mapping-unit count. For example,
176 ROPs / ... TMUsis expected for a desktop RTX 5090. - Capture evidence. Screenshot the GPU name, ROPs/TMUs field, BIOS version, and driver information. If support requests it, save a GPU-Z report. You can save the VBIOS by clicking the small arrow beside BIOS Version and choosing Save to file; NVIDIA documents this process here.
- Compare the count with the correct desktop or laptop specification below.
Expected RTX 50-series ROP counts
Desktop and laptop counts are not interchangeable. These model-specific figures are listed in ASUS ROG’s specification guidance.
| Product | Expected ROPs | Example reading to investigate |
|---|---|---|
| Desktop RTX 5090 / 5090D | 176 | 168 |
| Desktop RTX 5080 | 112 | 104 |
| Desktop RTX 5070 Ti | 96 | 88 |
| Laptop RTX 5090 | 112 | Compare with the exact laptop specification |
| Laptop RTX 5080 | 96 | Compare with the exact laptop specification |
| Laptop RTX 5070 Ti | 80 | Compare with the exact laptop specification |
The desktop RTX 5090 example is the clearest documented case: an affected card showed 168 rather than 176 reported ROPs. NVIDIA’s “one fewer ROP unit” terminology corresponds to an eight-ROP difference in the conventional count shown by diagnostic software.

How to interpret the result
The count matches
The card passes this particular missing-ROP check. Keep the screenshot if the card is new or you may need to return it. A correct ROP count does not rule out unrelated thermal, power, driver, or stability problems.
The count is lower with no driver installed
Install the official driver, reboot, and check again. A driverless GPU-Z reading may come from its static database and is not sufficient evidence for an RMA.
The count remains lower with the driver active
Confirm the exact model and form factor, update GPU-Z, reboot once more, and verify the specification using an authoritative source such as the manufacturer or TechPowerUp’s GPU database. If the discrepancy remains, document it and contact the graphics-card board manufacturer for warranty service or replacement.

Two utilities disagree
- Check that both utilities are reading the same GPU.
- Confirm that the NVIDIA driver is installed and active.
- Update both utilities.
- Determine whether one is using a static database value.
- Check that the comparison specification matches the desktop or laptop version.
For this investigation, the driver-enabled GPU-Z result should be the primary software reading because the documented anomaly was detected through the live NVIDIA interface.

What to do if ROPs appear to be missing
- Reboot and repeat the GPU-Z check.
- If the system has integrated graphics, confirm that GPU-Z is showing the discrete card.
- Reinstall the official NVIDIA driver using a clean-install option if available.
- Download the latest GPU-Z release and check again.
- If practical, test the card in a second system.
- Save screenshots, the GPU-Z report, purchase details, serial number, BIOS information, and proof of purchase.
- Contact the board manufacturer—the company named on the card and invoice—not just NVIDIA, especially for a partner card.
NVIDIA’s reported remedy for confirmed affected cards was to contact the board manufacturer for replacement. Founders Edition warranty coverage and exclusions are described in NVIDIA’s warranty information; partner-card policies vary by manufacturer and region.
Do not flash a random VBIOS
A VBIOS update is not an established consumer fix for this issue. If a ROP partition is disabled at the hardware level, software may not be able to restore it. An incorrect VBIOS can also make the card unusable or complicate a warranty claim.
Preserve the original BIOS, do not overclock while diagnosing, and do not disassemble the cooler. Only install a VBIOS supplied for the exact SKU by the card manufacturer, and only when the manufacturer specifically instructs you to do so. If the card has a dual-BIOS switch, use another position only as permitted by the manual; changing BIOS modes should not be presented as a way to restore hardware units.

Can benchmarking confirm missing ROPs?
No. A benchmark can corroborate a suspected performance difference but cannot prove that ROPs are missing. At stock settings, run a repeatable benchmark such as 3DMark, then compare the result with the same model, clock class, driver, resolution, and test settings.

Check more than one game because ROP-limited workloads can show a larger effect than other workloads. Also check temperatures, power limit, boost clocks, PCIe link width, CPU bottlenecks, background processes, driver settings, factory BIOS mode, and system stability. NVIDIA’s reported average graphics-performance impact was about 4%, not a guaranteed 4% loss in every game.
Simple decision tree
- ROP count matches: No evidence of the known missing-ROP issue; investigate other causes of poor performance.
- Lower count without a driver: Install the driver, reboot, and recheck.
- Lower count with the driver installed: Verify the exact specification, update GPU-Z, capture evidence, and contact the board manufacturer.
- Low benchmark but correct ROP count: Investigate thermals, power, clocks, PCIe configuration, CPU limits, drivers, and benchmark settings.
How widespread was the issue?
The reported problem was rare and not present in every card of an affected model. NVIDIA stated that fewer than 0.5% of RTX 5090/5090D and RTX 5070 Ti units were affected, according to TechPowerUp. Do not automatically apply that figure to later-reported RTX 5080 cards or laptop products. The safest approach is to check the individual card.

Can missing ROPs be repaired?
Do not assume they can be restored by software. If the reduced count remains in driver-enabled GPU-Z after verification, request warranty replacement from the board manufacturer.
Does reinstalling the driver restore missing ROPs?
It can correct a reporting problem, but it cannot necessarily restore a hardware-disabled ROP partition. Reinstalling the driver is a verification step, not a guaranteed repair.

Are laptop and desktop ROP counts the same?
No. For example, the desktop RTX 5090 is listed at 176 ROPs, while the RTX 5090 Laptop GPU is listed at 112. Always use the specification for the exact form factor.
Does a lower benchmark prove missing ROPs?
No. Benchmarks are affected by clocks, thermals, power limits, drivers, CPU performance, PCIe configuration, and settings. Use GPU-Z for the primary check and benchmarks only as supporting evidence.
Should I return the card?
If the lower count persists after driver-enabled verification and matches no valid specification, save evidence and contact the retailer or board manufacturer about an RMA or replacement. Do not modify the card first.
The Bottom Line
Install the NVIDIA driver, run the latest TechPowerUp GPU-Z, and check the first number in ROPs/TMUs. Compare it with the exact desktop or laptop specification. A persistent mismatch—such as 168 instead of 176 on a desktop RTX 5090—warrants documentation and a board-manufacturer warranty request, not an unofficial VBIOS flash.
