Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 512MB		105 Watts
Radeon RX 6500 XT		107 Watts
	Difference: 2 Watts (2%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6500 XT should be 156% faster than the GeForce 8800 GT 512MB in general, due to its higher data rate. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 89856 (156%)

Texel Rate

The Radeon RX 6500 XT is much (approximately 319%) better at AF than the GeForce 8800 GT 512MB. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 107200 (319%)

Pixel Rate

The Radeon RX 6500 XT should be a lot (more or less 633%) better at anti-aliasing than the GeForce 8800 GT 512MB, and will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 60800 (633%)

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 maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units by the core clock 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 applied in one second.

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