GeForce RTX 2080 SUPER vs Radeon RX 7900 XTX

Intro

Compare all of that to the Radeon RX 7900 XTX, which has a GPU core clock speed of 1855 MHz, and 24576 MB of GDDR6 RAM running at 2500 MHz through a 384-bit bus. It also is comprised of 6144 SPUs, 384 TAUs, and 192 ROPs.

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

Memory Bandwidth

As far as performance goes, the Radeon RX 7900 XTX should in theory be a lot better than the GeForce RTX 2080 SUPER in general. (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 should be a lot (about 125%) more effective at anisotropic 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 running with lots of anti-aliasing 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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 texture map elements (texels) that are processed per second. This number is calculated 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
