GeForce RTX 2080 SUPER vs Radeon RX 6950 XT

Intro

The GeForce RTX 2080 SUPER uses a 12 nm design. nVidia has set the core speed at 1650 MHz. The GDDR6 memory runs at a frequency of 1937 MHz on this card. It features 3072 SPUs as well as 192 TAUs and 64 Rasterization Operator Units.

Compare those specs to the Radeon RX 6950 XT, which has GPU clock speed of 1925 MHz, and 16384 MB of GDDR6 memory set to run at 2250 MHz through a 256-bit bus. It also is comprised of 5120 SPUs, 320 TAUs, and 128 Raster Operation Units.

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 will be 16% faster than the GeForce RTX 2080 SUPER in general, because of its higher bandwidth. (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 (approximately 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

If using a high resolution 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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 are processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
