Radeon R7 250X vs Radeon RX 5500 XT

Intro

Compare all of that to the Radeon RX 5500 XT, which has a clock frequency of 1717 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 128-bit bus, and makes use of a 7 nm design. It is comprised of 1408 SPUs, 88 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 250X		95 Watts
Radeon RX 5500 XT		130 Watts
	Difference: 35 Watts (37%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5500 XT will be 219% quicker than the Radeon R7 250X in general, because of its higher bandwidth. (explain)

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

Texel Rate

The Radeon RX 5500 XT will be much (more or less 278%) more effective at anisotropic filtering than the Radeon R7 250X. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 5500 XT is a better choice, and very much so. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Radeon R7 250X		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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
