GeForce RTX 2080 SUPER vs Radeon RX 7900 XTX

Intro

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

Compare that to the Radeon RX 7900 XTX, which makes use of a 5 nm design. AMD has clocked the core frequency at 1855 MHz. The GDDR6 memory is set to run at a frequency of 2500 MHz on this card. It features 6144 SPUs as well as 384 TAUs and 192 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080 SUPER 250 Watts
Radeon RX 7900 XTX 355 Watts
Difference: 105 Watts (42%)

Memory Bandwidth

In theory, the Radeon RX 7900 XTX will be 94% faster than the GeForce RTX 2080 SUPER in general, because of its greater data rate. (explain)

Radeon RX 7900 XTX 983040 MB/sec
GeForce RTX 2080 SUPER 507904 MB/sec
Difference: 475136 (94%)

Texel Rate

The Radeon RX 7900 XTX is quite a bit (approximately 125%) more effective at texture filtering than the GeForce RTX 2080 SUPER. (explain)

Radeon RX 7900 XTX 712320 Mtexels/sec
GeForce RTX 2080 SUPER 316800 Mtexels/sec
Difference: 395520 (125%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 7900 XTX is the winner, and very much so. (explain)

Radeon RX 7900 XTX 356160 Mpixels/sec
GeForce RTX 2080 SUPER 105600 Mpixels/sec
Difference: 250560 (237%)

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 max amount of information (in units of MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 reach the maximum fill rate.
