Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 580 3GB		244 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 6 Watts (2%)

Memory Bandwidth

In theory, the Radeon RX 6750 XT should be 130% faster than the GeForce GTX 580 3GB in general, because of its higher bandwidth. (explain)

Radeon RX 6750 XT		442368 MB/sec
GeForce GTX 580 3GB		192384 MB/sec
	Difference: 249984 (130%)

Texel Rate

The Radeon RX 6750 XT should be a lot (about 596%) faster with regards to anisotropic filtering than the GeForce GTX 580 3GB. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 294592 (596%)

Pixel Rate

The Radeon RX 6750 XT will be much (about 271%) better at AA than the GeForce GTX 580 3GB, and should be able to handle higher screen resolutions better. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
GeForce GTX 580 3GB		37056 Mpixels/sec
	Difference: 100544 (271%)

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 moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
