The Radeon RX 5500 XT is a lot (about 278%) better at texture filtering than the Radeon R7 250X 2GB. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 111096 (278%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5500 XT is superior to the Radeon R7 250X 2GB, by a large margin. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 38944 (243%)

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 information (in units of MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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