Radeon R9 280X vs Radeon RX 5600 XT

Intro

Compare that to the Radeon RX 5600 XT, which comes with a GPU core clock speed of 1375 MHz, and 6144 MB of GDDR6 RAM running at 1500 MHz through a 192-bit bus. It also is comprised of 2304 Stream Processors, 144 Texture Address Units, and 64 Raster Operation Units.

Texel Rate

The Radeon RX 5600 XT should be much (more or less 82%) more effective at anisotropic filtering than the Radeon R9 280X. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon R9 280X		108800 Mtexels/sec
	Difference: 89200 (82%)

Pixel Rate

The Radeon RX 5600 XT should be much (more or less 224%) faster with regards to AA than the Radeon R9 280X, and also will be able to handle higher resolutions while still performing well. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon R9 280X		27200 Mpixels/sec
	Difference: 60800 (224%)

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 (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
