Radeon R9 280X vs Radeon RX 5600

Intro

Compare those specs to the Radeon RX 5600, which comes with GPU clock speed of 1375 MHz, and 6144 MB of GDDR6 memory set to run at 1500 MHz through a 192-bit bus. It also features 2048 Stream Processors, 128 Texture Address Units, and 64 Raster Operation Units.

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

Texel Rate

The Radeon RX 5600 should be much (more or less 62%) faster with regards to AF 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 quite a bit (about 224%) more effective at anti-aliasing than the Radeon R9 280X, and also able to handle higher screen resolutions better. (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 largest amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 processed 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 better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
