VS

Geforce GTX 1080 Ti vs Radeon RX 6950 XT

Intro

The Geforce GTX 1080 Ti comes with clock speeds of 1480 MHz on the GPU, and 1376 MHz on the 11264 MB of GDDR5X RAM. It features 3584 SPUs along with 224 TAUs and 88 Rasterization Operator Units.

Compare those specs to the Radeon RX 6950 XT, which features a clock speed of 1925 MHz and a GDDR6 memory speed of 2250 MHz. It also uses a 256-bit memory bus, and makes use of a 7 nm design. It is made up of 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.

Geforce GTX 1080 Ti 495616 MB/sec
Difference: 94208 (19%)

Texel Rate

The Radeon RX 6950 XT will be quite a bit (more or less 86%) faster with regards to anisotropic filtering than the Geforce GTX 1080 Ti. (explain)

Radeon RX 6950 XT 616000 Mtexels/sec
Geforce GTX 1080 Ti 331520 Mtexels/sec
Difference: 284480 (86%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6950 XT is superior to the Geforce GTX 1080 Ti, and very much so. (explain)

Radeon RX 6950 XT 246400 Mpixels/sec
Geforce GTX 1080 Ti 130240 Mpixels/sec
Difference: 116160 (89%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
