Radeon RX 470 4GB vs Radeon RX 5500 XT

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470 4GB		120 Watts
Radeon RX 5500 XT		130 Watts
	Difference: 10 Watts (8%)

Memory Bandwidth

In theory, the Radeon RX 5500 XT should be 9% faster than the Radeon RX 470 4GB overall, because of its higher data rate. (explain)

Radeon RX 5500 XT		229376 MB/sec
Radeon RX 470 4GB		211200 MB/sec
	Difference: 18176 (9%)

Texel Rate

The Radeon RX 5500 XT will be a lot (about 27%) more effective at AF than the Radeon RX 470 4GB. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 32568 (27%)

Pixel Rate

If using 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 RX 470 4GB		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 maximum amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
