Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTS (G80) 640MB		143 Watts
Radeon RX 5600 XT		160 Watts
	Difference: 17 Watts (12%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 XT will be 443% quicker than the GeForce 8800 GTS (G80) 640MB overall, because of its higher data rate. (explain)

Radeon RX 5600 XT		344064 MB/sec
GeForce 8800 GTS (G80) 640MB		63360 MB/sec
	Difference: 280704 (443%)

Texel Rate

The Radeon RX 5600 XT is much (about 704%) more effective at texture filtering than the GeForce 8800 GTS (G80) 640MB. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
GeForce 8800 GTS (G80) 640MB		24624 Mtexels/sec
	Difference: 173376 (704%)

Pixel Rate

The Radeon RX 5600 XT should be quite a bit (more or less 758%) better at FSAA than the GeForce 8800 GTS (G80) 640MB, and will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
GeForce 8800 GTS (G80) 640MB		10260 Mpixels/sec
	Difference: 77740 (758%)

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 (counted in MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
