Radeon R9 280X vs Radeon RX 5600 XT

Intro

Compare all of that to the Radeon RX 5600 XT, which has a GPU core clock speed of 1375 MHz, and 6144 MB of GDDR6 memory running at 1500 MHz through a 192-bit bus. It also is made up of 2304 SPUs, 144 Texture Address Units, and 64 Raster Operation Units.

Radeon RX 5600 XT		160 Watts
Radeon R9 280X		250 Watts
	Difference: 90 Watts (56%)

Memory Bandwidth

In theory, the Radeon RX 5600 XT should be 19% quicker than the Radeon R9 280X in general, because of its greater data rate. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon R9 280X		288000 MB/sec
	Difference: 56064 (19%)

Texel Rate

The Radeon RX 5600 XT is quite a bit (more or less 82%) faster with regards to AF than the Radeon R9 280X. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 5600 XT is superior to the Radeon R9 280X, by a large margin. (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 data (counted in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
