Radeon R7 250X vs Radeon RX 5500

Intro

Compare all that to the Radeon RX 5500, which makes use of a 7 nm design. AMD has clocked the core frequency at 1670 MHz. The GDDR6 RAM is set to run at a frequency of 1750 MHz on this specific model. It features 1408 SPUs as well as 88 Texture Address Units and 32 Rasterization Operator Units.

	Difference: 55 Watts (58%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5500 is 219% faster than the Radeon R7 250X in general, due to its greater bandwidth. (explain)

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

Texel Rate

The Radeon RX 5500 is a lot (about 267%) more effective at anisotropic filtering than the Radeon R7 250X. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5500 is superior to the Radeon R7 250X, by far. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon R7 250X		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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
