In theory, the Radeon RX 6750 XT will be 514% faster than the Radeon R7 250X 2GB in general, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon RX 6750 XT will be much (about 760%) better at AF 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

If using lots of anti-aliasing is important to you, then the Radeon RX 6750 XT is the winner, by a large margin. (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 maximum amount of data (measured in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock 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 output 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 max fill rate.
