Radeon HD 6750		64000 MB/sec
	Difference: 83456 (130%)

Texel Rate

The Radeon RX 6500 XT will be a lot (about 439%) more effective at anisotropic filtering than the Radeon HD 6750. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 114700 (439%)

Pixel Rate

The Radeon RX 6500 XT should be quite a bit (more or less 507%) faster with regards to anti-aliasing than the Radeon HD 6750, and also will be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 58800 (507%)

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: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are 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 the texel rate, the better the graphics 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 maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. 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 - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
