Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Performance-wise, the Radeon RX 5500 XT should in theory be a bit superior to the Radeon RX 470 in general. (explain)

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

Texel Rate

The Radeon RX 5500 XT should be much (more or less 27%) more effective at AF than the Radeon RX 470. (explain)

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

Pixel Rate

The Radeon RX 5500 XT will be a lot (approximately 85%) faster with regards to anti-aliasing than the Radeon RX 470, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
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 megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, 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 amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
