Radeon RX 470 4GB vs Radeon RX 5500 XT

Intro

Compare those specifications to the Radeon RX 5500 XT, which uses a 7 nm design. AMD has set the core speed at 1717 MHz. The GDDR6 RAM runs at a speed of 1750 MHz on this specific model. It features 1408 SPUs as well as 88 Texture Address Units and 32 Rasterization Operator Units.

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

Memory Bandwidth

As far as performance goes, the Radeon RX 5500 XT should in theory be a small bit better than the Radeon RX 470 4GB in general. (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 is quite a bit (approximately 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 lots of anti-aliasing is important to you, then the Radeon RX 5500 XT is the winner, by far. (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 max amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
