GeForce RTX 2080 Ti vs Radeon RX 6950 XT

Intro

The GeForce RTX 2080 Ti makes use of a 12 nm design. nVidia has set the core frequency at 1350 MHz. The GDDR6 RAM works at a speed of 1750 MHz on this specific card. It features 4352 SPUs as well as 272 TAUs and 88 ROPs.

Compare all that to the Radeon RX 6950 XT, which features a core clock speed of 1925 MHz and a GDDR6 memory frequency of 2250 MHz. It also makes use of a 256-bit memory bus, and makes use of a 7 nm design. It is comprised of 5120 SPUs, 320 TAUs, and 128 Raster Operation Units.

Radeon RX 6950 XT 616000 Mtexels/sec
GeForce RTX 2080 Ti 367200 Mtexels/sec
Difference: 248800 (68%)

Pixel Rate

The Radeon RX 6950 XT will be much (approximately 107%) more effective at full screen anti-aliasing than the GeForce RTX 2080 Ti, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6950 XT 246400 Mpixels/sec
GeForce RTX 2080 Ti 118800 Mpixels/sec
Difference: 127600 (107%)

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 maximum amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
