Radeon HD 6750		64000 MB/sec
	Difference: 165376 (258%)

Texel Rate

The Radeon RX 6600 is a lot (about 598%) better at AF than the Radeon HD 6750. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 156012 (598%)

Pixel Rate

The Radeon RX 6600 should be a lot (more or less 797%) faster with regards to full screen anti-aliasing than the Radeon HD 6750, and also will be capable of handling higher screen resolutions better. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon HD 6750		11600 Mpixels/sec
	Difference: 92464 (797%)

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 data (counted in MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount 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 better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
