Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB		105 Watts
Radeon RX 7900 XT		300 Watts
	Difference: 195 Watts (186%)

Memory Bandwidth

In theory, the Radeon RX 7900 XT should be 1322% quicker than the GeForce 8800 GT 1GB in general, because of its higher data rate. (explain)

Radeon RX 7900 XT		819200 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 761600 (1322%)

Texel Rate

The Radeon RX 7900 XT will be a lot (more or less 1400%) better at AF than the GeForce 8800 GT 1GB. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 470400 (1400%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 7900 XT is a better choice, and very much so. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 278400 (2900%)

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 information (in units of MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
