Radeon RX 480 vs Radeon RX 5700 XT

Intro

Compare all that to the Radeon RX 5700 XT, which features a core 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 made up of 2560 SPUs, 160 TAUs, and 64 ROPs.

Radeon RX 480		161280 Mtexels/sec
	Difference: 95520 (59%)

Pixel Rate

The Radeon RX 5700 XT is a lot (about 187%) faster with regards to full screen anti-aliasing than the Radeon RX 480, and will be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 66880 (187%)

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 data (measured in megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
