Radeon R9 280 vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which has GPU core speed of 1375 MHz, and 6144 MB of GDDR6 RAM running at 1500 MHz through a 192-bit bus. It also is made up of 2048 Stream Processors, 128 Texture Address Units, and 64 ROPs.

Radeon R9 280		240000 MB/sec
	Difference: 54912 (23%)

Texel Rate

The Radeon RX 5600 will be quite a bit (about 68%) better at anisotropic filtering than the Radeon R9 280. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon R9 280		104496 Mtexels/sec
	Difference: 71504 (68%)

Pixel Rate

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

Radeon RX 5600		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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB 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. If it uses DDR memory, it must 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
