Radeon R9 280X vs Radeon RX 5600

Intro

Compare those specifications to the Radeon RX 5600, which has a clock frequency of 1375 MHz and a GDDR6 memory speed of 1500 MHz. It also uses a 192-bit memory bus, and uses a 7 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 64 ROPs.

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

Texel Rate

The Radeon RX 5600 should be quite a bit (approximately 62%) better at 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

If running with lots of anti-aliasing is important to you, then the Radeon RX 5600 is a better choice, by far. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
