Radeon R7 250X		72000 MB/sec
	Difference: 272064 (378%)

Texel Rate

The Radeon RX 5600 XT should be a lot (about 395%) faster with regards to anisotropic filtering than the Radeon R7 250X. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 158000 (395%)

Pixel Rate

The Radeon RX 5600 XT is a lot (about 450%) more effective at full screen anti-aliasing than the Radeon R7 250X, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 72000 (450%)

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 largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If 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 number of texture map elements (texels) that are processed per second. This figure is calculated 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
