The Radeon RX 6500 XT is a lot (more or less 252%) faster with regards to texture filtering than the Radeon R7 250X. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 100800 (252%)

Pixel Rate

The Radeon RX 6500 XT should be quite a bit (about 340%) better at FSAA than the Radeon R7 250X, and will be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 54400 (340%)

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 (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 can be applied in one second. This is calculated by multiplying the total amount 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
