Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080 SUPER		250 Watts
Radeon R9 295X2		500 Watts
	Difference: 250 Watts (100%)

Memory Bandwidth

In theory, the Radeon R9 295X2 should be 26% faster than the GeForce RTX 2080 SUPER overall, because of its greater bandwidth. (explain)

Radeon R9 295X2		640000 MB/sec
GeForce RTX 2080 SUPER		507904 MB/sec
	Difference: 132096 (26%)

Texel Rate

The Radeon R9 295X2 should be a little bit (approximately 13%) better at anisotropic filtering than the GeForce RTX 2080 SUPER. (explain)

Radeon R9 295X2		358336 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 41536 (13%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 295X2 is the winner, and very much so. (explain)

Radeon R9 295X2		130304 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 24704 (23%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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