Radeon RX 570 vs Radeon RX 5700 XT

Intro

Compare those specs to the Radeon RX 5700 XT, which comes with a clock speed of 1605 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 256-bit memory bus, and makes use of a 7 nm design. It is comprised of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 570		150 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 75 Watts (50%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 XT is 100% quicker than the Radeon RX 570 in general, because of its higher data rate. (explain)

Radeon RX 5700 XT		458752 MB/sec
Radeon RX 570		229376 MB/sec
	Difference: 229376 (100%)

Texel Rate

The Radeon RX 5700 XT will be a lot (approximately 72%) better at texture filtering than the Radeon RX 570. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
Radeon RX 570		149504 Mtexels/sec
	Difference: 107296 (72%)

Pixel Rate

The Radeon RX 5700 XT will be quite a bit (more or less 175%) more effective at anti-aliasing than the Radeon RX 570, and capable of handling higher screen resolutions better. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 65344 (175%)

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 largest amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of 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 that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate 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 filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
