Radeon RX 470 vs Radeon RX 5500 XT

Intro

Compare all that to the Radeon RX 5500 XT, which has GPU clock speed of 1717 MHz, and 8192 MB of GDDR6 RAM running at 1750 MHz through a 128-bit bus. It also is comprised of 1408 SPUs, 88 TAUs, and 32 ROPs.

Radeon RX 470		211200 MB/sec
	Difference: 18176 (9%)

Texel Rate

The Radeon RX 5500 XT is a lot (about 27%) better at texture filtering than the Radeon RX 470. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon RX 470		118528 Mtexels/sec
	Difference: 32568 (27%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5500 XT is the winner, by a large margin. (explain)

Radeon RX 470		29632 Mpixels/sec
	Difference: 25312 (85%)

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 max amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
