We previously covered that NVIDIA's GeForce RTX 5090 and RTX 5070 Ti chips were spotted with a few missing ROPs. NVIDIA confirmed this issue affects 0.5% of the supply of GeForce RTX 5090 / 5090D and 5070 Ti GPUs, and users should contact their vendors for a replacement. However, the case of missing ROPs is now extended further, with one user on Reddit reporting that his latest GeForce RTX 5080 Founders Edition GPU is reading only 104 ROPs, instead of the regular 112. That is eight missing ROPs—a number similar to eight missing ROPs found on GeForce RTX 5090 and RTX 5070 Ti. To double-check, the user installed the latest version of NVIDIA drivers and still recorded 104 ROPs only.
We previously found eight missing ROPs constitute a 4.54% loss in the GPU's raster hardware capability. The GPU's Raster Operations Pipeline (ROP) units handle the final stages of graphics processing—they manage pixel-level operations like blending colors, smoothing edges through antialiasing, writing pixels to texture memory, and ultimately storing the final pixel values in the frame buffer. This differs from shading units (GPU cores), which focus on calculating the colors, lighting effects, and material properties of pixels and vertices during rendering but don't directly work with the frame buffer. The performance loss from missing ROPs will differ from game to game, depending on whether a game heavily relies on ROP-intensive operations. Nonetheless, with GeForce RTX 5080 FE in the picture, we must wait and see if more future SKUs may appear with missing ROPs.

" issue eh?
