Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 XT		225 Watts
Radeon RX 6750 XT		250 Watts
	Difference: 25 Watts (11%)

Memory Bandwidth

In theory, the Radeon RX 5700 XT is 4% faster than the Radeon RX 6750 XT in general, because of its higher data rate. (explain)

Radeon RX 5700 XT		458752 MB/sec
Radeon RX 6750 XT		442368 MB/sec
	Difference: 16384 (4%)

Texel Rate

The Radeon RX 6750 XT will be quite a bit (more or less 34%) faster with regards to AF than the Radeon RX 5700 XT. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 87200 (34%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6750 XT is the winner, and very much so. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon RX 5700 XT		102720 Mpixels/sec
	Difference: 34880 (34%)

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 transported across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
