Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
Radeon RX 6500 XT		107 Watts
	Difference: 64 Watts (149%)

Memory Bandwidth

In theory, the Radeon RX 6500 XT is 483% faster than the GeForce GT 320 overall, because of its greater data rate. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 122176 (483%)

Texel Rate

The Radeon RX 6500 XT is a lot (more or less 986%) faster with regards to anisotropic filtering than the GeForce GT 320. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 127840 (986%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6500 XT is the winner, by far. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 66080 (1530%)

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 largest amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 can be processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better 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 most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
