GeForce GTX 285 2GB		204 Watts
	Difference: 97 Watts (91%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 285 2GB will be 8% faster than the Radeon RX 6500 XT in general, because of its higher bandwidth. (explain)

GeForce GTX 285 2GB		158976 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 11520 (8%)

Texel Rate

The Radeon RX 6500 XT is a lot (approximately 172%) better at texture filtering than the GeForce GTX 285 2GB. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 285 2GB		51840 Mtexels/sec
	Difference: 88960 (172%)

Pixel Rate

The Radeon RX 6500 XT should be much (about 240%) better at anti-aliasing than the GeForce GTX 285 2GB, and capable of handling higher resolutions more effectively. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 285 2GB		20736 Mpixels/sec
	Difference: 49664 (240%)

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 information (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
