Facepalm: Nvidia’s RTX 50 sequence has skilled one of the unpopular launches in latest reminiscence, with moderate-at-best efficiency positive aspects, extreme provide constraints, and dramatically inflated costs from board companions. To make issues worse, some clients have begun reporting models with faulty parts, resulting in barely decrease efficiency.
The few fortunate customers who acquired Nvidia’s flagship RTX 5090 quickly after its preliminary launch ought to run GPU-Z to examine if all 176 of the graphics card’s ROP models are functioning correctly. Some clients lately complained upon receiving GPUs with solely 168 enabled, lowering efficiency by as much as 5 % relying on the workload. Whether or not the issue is expounded to software program or {hardware} stays unclear.
Raster Operations Pipeline (ROP) models carry out one of many last steps within the rasterization course of, which calculates onscreen pixels. Nvidia’s white paper on the RTX 50 sequence’ Blackwell structure states that the 5090 options 176 ROPs, which TechPowerUp’s GPU-Z software program confirms.

Nevertheless, a person on the outlet’s boards noticed that GPU-Z detected solely 168 ROPs on their Zotac RTX 5090 Stable mannequin. TechPowerUp confirmed the discrepancy when testing that mannequin, observing minor efficiency drops relying on the sport regardless of sustaining the identical clock pace as GPUs from completely different board companions.
Elden Ring, when modded to take away its 60fps body fee cap, noticed the biggest divergence, dropping by 5.6% to 174fps from the 184fps noticed in Nvidia’s Founders Version reference mannequin. Nevertheless, different video games like Starfield and Doom Everlasting, with ray tracing enabled within the latter, skilled just about no degradation.
Moreover, the issue is not restricted to Zotac graphics playing cards, nor does it lengthen to all Zotac models. Following the preliminary report, different customers on Twitter and the Chiphell boards shared comparable GPU-Z experiences from MSI, Gigabyte, and Founders Version fashions. Some additionally appear to have Zotac variations with all 176 ROPs enabled.
The foundation trigger is the chip. A small batch of GB202 is flawed, and the bios cannot do something with this challenge.

It is speculated that the issue stems from a {hardware} challenge reasonably than software program as reinstalling drivers, reinstalling Home windows, and altering the GPU BIOS don’t repair the issue. Trusted leaker MEGAsizeGPU claims {that a} faulty batch of GB202 processors is accountable, suggesting that impacted models would possibly must be changed.
In a press release despatched to The Verge, Nvidia confirmed that it found a problem affecting lower than half a % of RTX 5090, 5090D, and 5070 Ti GPUs, which shipped with a minimum of one ROP lacking. This may have an effect on gaming efficiency by round 4 %, however AI and compute efficiency are unaffected. The corporate has corrected the manufacturing glitch and advises impacted clients to contact board distributors.
The RTX 5090 and 5090D are the one GPUs confirmed to be lacking ROPs to date. Some customers grew to become involved after their 5080s reported “112 out of 128” models, however 112 is the right variety of ROPs for that card.
