Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X		95 Watts
Radeon RX 5600 XT		160 Watts
	Difference: 65 Watts (68%)

Memory Bandwidth

In theory, the Radeon RX 5600 XT is 378% quicker than the Radeon R7 250X overall, due to its greater data rate. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 272064 (378%)

Texel Rate

The Radeon RX 5600 XT should be a lot (about 395%) better at texture 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 will be quite a bit (approximately 450%) better at full screen anti-aliasing than the Radeon R7 250X, and also should be capable of handling higher resolutions without slowing down too much. (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: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved past the external memory interface in 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 type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher 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 most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 fill rate is also dependant 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.
