Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X 2GB		95 Watts
Radeon RX 5500		150 Watts
	Difference: 55 Watts (58%)

Memory Bandwidth

In theory, the Radeon RX 5500 should be 219% faster than the Radeon R7 250X 2GB in general, because of its higher data rate. (explain)

Radeon RX 5500		229376 MB/sec
Radeon R7 250X 2GB		72000 MB/sec
	Difference: 157376 (219%)

Texel Rate

The Radeon RX 5500 is quite a bit (approximately 267%) better at AF than the Radeon R7 250X 2GB. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon R7 250X 2GB		40000 Mtexels/sec
	Difference: 106960 (267%)

Pixel Rate

The Radeon RX 5500 is quite a bit (about 234%) faster with regards to AA than the Radeon R7 250X 2GB, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 37440 (234%)

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 largest amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video 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 the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
