Radeon R9 280 vs Radeon RX 5600 XT

Intro

Compare those specs to the Radeon RX 5600 XT, which comes with core clock speeds of 1375 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 memory. It features 2304 SPUs as well as 144 Texture Address Units and 64 Rasterization Operator Units.

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 a lot faster than the Radeon R9 280 overall. (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 quite a bit (about 89%) more effective at AF than the Radeon R9 280. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 5600 XT is a better choice, and very much so. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
