GeForce RTX 2080 SUPER vs Radeon RX 6950 XT

Intro

Compare those specifications to the Radeon RX 6950 XT, which features clock speeds of 1925 MHz on the GPU, and 2250 MHz on the 16384 MB of GDDR6 RAM. It features 5120 SPUs along with 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% quicker than the GeForce RTX 2080 SUPER overall, due to 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 AF 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

The Radeon RX 6950 XT should be quite a bit (more or less 133%) better at AA than the GeForce RTX 2080 SUPER, and will be able to handle higher screen resolutions without slowing down too much. (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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
