RTX 5080 now examined with lacking ROPs, loses much more efficiency than the 5090

Final week, a TechPowerUp discussion board person made an attention-grabbing discovery, stating that their Zotac RTX 5090 Strong had lacking ROPs, leading to a 4.54% efficiency loss in comparison with different RTX 5090 fashions. Quickly after, extra reviews started surfacing, with customers noticing fewer ROPs than the official specs on China-exclusive MSI RTX 5090D and Manli 5090D playing cards.

In response, Nvidia informed Tom’s {Hardware} that it is a uncommon difficulty affecting lower than 0.5% (half a p.c) of GeForce RTX 5090, 5090D, and 5070 Ti GPUs. Because the RTX 5080 wasn’t talked about, we assumed there wouldn’t be any unhealthy information about it. Nevertheless, it seems that it additionally has a faulty chip. This comes from Reddit the place an RTX 5080 Founders Version proprietor reported going through the identical lacking ROPs difficulty.

Lacking ROPs end in over 14% efficiency loss for the 5080

Within the unique Reddit put up, the person talked about that their RTX 5080 Founders Version is 8 ROPs quick, that means that as an alternative of the 112 ROPs NVIDIA meant, their card solely has 104. At first, different customers identified that the RTX 5080 proprietor had not chosen the Vulkan help field in GPU-Z, however even after enabling it, GPU-Z nonetheless confirmed solely 104 ROPs.

Naturally, the customer determined to place their underpowered card to the check to see how a lot of a efficiency distinction this truly makes. They printed a Time Spy benchmark consequence, and when in comparison with a GeForce RTX 5080 Founders Version that includes all 112 ROPs, the underpowered RTX 5080 is 14.5% behind. So, efficiency takes a giant hit as a result of what appears to be simply 8 lacking ROPs.

Fortunately, you may get a alternative

On the brilliant facet, Nvidia has acknowledged that “affected customers can contact the board producer for a alternative,” although this was particularly in reference to the RTX 5090 and 5090D lacking ROPs that surfaced earlier. Because the RTX 5080 difficulty is new, it hasn’t been immediately addressed, however given the similarity, Nvidia will possible provide replacements for affected RTX 5080 homeowners as properly.

That stated, Nvidia additionally talked about that the manufacturing anomaly has been corrected, that means no future RTX 50 collection fashions will ship with this drawback. Nevertheless, should you already personal an RTX 50 collection GPU, it is price checking the ROP rely—you is likely to be one of many “fortunate” few with an underpowered card.
