Radeon RX 6750 XT		442368 MB/sec
Radeon R7 250X 2GB		72000 MB/sec
	Difference: 370368 (514%)

Texel Rate

The Radeon RX 6750 XT is quite a bit (more or less 760%) better at anisotropic filtering than the Radeon R7 250X 2GB. (explain)

Radeon RX 6750 XT		344000 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 304000 (760%)

Pixel Rate

The Radeon RX 6750 XT will be quite a bit (about 760%) better at FSAA than the Radeon R7 250X 2GB, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6750 XT		137600 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 121600 (760%)

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 data (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 are applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
