GeForce RTX 2080 SUPER vs Radeon RX 6950 XT

Intro

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

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

Memory Bandwidth

Theoretically, the Radeon RX 6950 XT should perform a little bit faster than the GeForce RTX 2080 SUPER overall. (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 much (about 94%) more effective 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

The Radeon RX 6950 XT will be quite a bit (approximately 133%) faster with regards to full screen anti-aliasing than the GeForce RTX 2080 SUPER, and also should be capable of handling higher screen resolutions without losing too much performance. (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 max amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
