VS

GeForce RTX 2080 SUPER vs Radeon RX 6950 XT

Intro

The GeForce RTX 2080 SUPER features core speeds of 1650 MHz on the GPU, and 1937 MHz on the 8192 MB of GDDR6 memory. It features 3072 SPUs along with 192 Texture Address Units and 64 ROPs.

Compare that to the Radeon RX 6950 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1925 MHz. The GDDR6 RAM works at a frequency of 2250 MHz on this specific card. 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, 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 should be a lot (more or less 94%) faster with regards to 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

If using a high screen resolution is important to you, then the Radeon RX 6950 XT is a better choice, by a large margin. (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 maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
