Radeon R9 280X vs Radeon RX 5600 XT

Intro

Compare those specifications to the Radeon RX 5600 XT, which uses a 7 nm design. AMD has set the core frequency at 1375 MHz. The GDDR6 RAM runs at a frequency of 1500 MHz on this particular model. It features 2304 SPUs along with 144 TAUs and 64 ROPs.

Radeon R9 280X		108800 Mtexels/sec
	Difference: 89200 (82%)

Pixel Rate

The Radeon RX 5600 XT will be quite a bit (about 224%) faster with regards to FSAA than the Radeon R9 280X, and capable of handling higher resolutions more effectively. (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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
