Radeon R9 280X vs Radeon RX 5600

Intro

The Radeon R9 280X has core clock speeds of 850 MHz on the GPU, and 1500 MHz on the 3072 MB of GDDR5 memory. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Compare those specs to the Radeon RX 5600, which has a clock speed of 1375 MHz and a GDDR6 memory frequency of 12000 MHz. It also features a 192-bit bus, and makes use of a 7 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

Radeon RX 5600 294912 MB/sec
Radeon R9 280X 288000 MB/sec
Difference: 6912 (2%)

Texel Rate

The Radeon RX 5600 should be quite a bit (more or less 62%) faster with regards to texture filtering than the Radeon R9 280X. (explain)

Radeon RX 5600 176000 Mtexels/sec
Radeon R9 280X 108800 Mtexels/sec
Difference: 67200 (62%)

Pixel Rate

The Radeon RX 5600 will be a lot (about 224%) more effective at AA than the Radeon R9 280X, and also able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 5600 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.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one 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 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 write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
