Radeon RX 470 vs Radeon RX 5500 XT

Intro

Compare those specs to the Radeon RX 5500 XT, which comes with 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 uses a 7 nm design. It is comprised of 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

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 theoretically be just 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 a lot (about 27%) more effective 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

The Radeon RX 5500 XT will be quite a bit (approximately 85%) faster with regards to AA than the Radeon RX 470, and will be able to handle higher screen resolutions without losing too much performance. (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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 per second. This 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 ability to reach the maximum fill rate.
