Radeon R9 280 vs Radeon RX 5600 XT

Intro

The Radeon R9 280 has a core clock speed of 933 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It features 1792 SPUs, 112 TAUs, and 32 Raster Operation Units.

Compare all that to the Radeon RX 5600 XT, which uses a 7 nm design. AMD has set the core frequency at 1375 MHz. The GDDR6 memory works at a speed of 1500 MHz on this card. It features 2304 SPUs along with 144 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Radeon RX 5600 XT should be 43% faster than the Radeon R9 280 in general, because of its greater bandwidth. (explain)

Radeon RX 5600 XT 344064 MB/sec
Radeon R9 280 240000 MB/sec
Difference: 104064 (43%)

Texel Rate

The Radeon RX 5600 XT should be a lot (about 89%) better at anisotropic filtering than the Radeon R9 280. (explain)

Radeon RX 5600 XT 198000 Mtexels/sec
Radeon R9 280 104496 Mtexels/sec
Difference: 93504 (89%)

Pixel Rate

The Radeon RX 5600 XT should be quite a bit (about 195%) faster with regards to anti-aliasing than the Radeon R9 280, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 5600 XT 88000 Mpixels/sec
Radeon R9 280 29856 Mpixels/sec
Difference: 58144 (195%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many 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.
