GeForce RTX 2080 SUPER vs Radeon RX 6950 XT

Intro

The GeForce RTX 2080 SUPER comes with a GPU core speed of 1650 MHz, and the 8192 MB of GDDR6 memory runs at 1937 MHz through a 256-bit bus. It also is comprised of 3072 SPUs, 192 TAUs, and 64 Raster Operation Units.

Compare those specifications to the Radeon RX 6950 XT, which has core speeds of 1925 MHz on the GPU, and 2250 MHz on the 16384 MB of GDDR6 RAM. It features 5120 SPUs as well as 320 Texture Address Units and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080 SUPER 250 Watts
Radeon RX 6950 XT 335 Watts
Difference: 85 Watts (34%)

Memory Bandwidth

In theory, the Radeon RX 6950 XT should be 16% faster than the GeForce RTX 2080 SUPER in general, because of its greater data rate. (explain)

Radeon RX 6950 XT 589824 MB/sec
GeForce RTX 2080 SUPER 507904 MB/sec
Difference: 81920 (16%)

Texel Rate

The Radeon RX 6950 XT is quite a bit (about 94%) better at texture filtering than the GeForce RTX 2080 SUPER. (explain)

Radeon RX 6950 XT 616000 Mtexels/sec
GeForce RTX 2080 SUPER 316800 Mtexels/sec
Difference: 299200 (94%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6950 XT is superior to the GeForce RTX 2080 SUPER, and very much so. (explain)

Radeon RX 6950 XT 246400 Mpixels/sec
GeForce RTX 2080 SUPER 105600 Mpixels/sec
Difference: 140800 (133%)

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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
