Radeon R9 280 vs Radeon RX 5600

Intro

Compare that to the Radeon RX 5600, which has GPU clock 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 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600		150 Watts
Radeon R9 280		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

As far as performance goes, the Radeon RX 5600 should in theory be much superior to the Radeon R9 280 overall. (explain)

Radeon RX 5600		294912 MB/sec
Radeon R9 280		240000 MB/sec
	Difference: 54912 (23%)

Texel Rate

The Radeon RX 5600 should be much (more or less 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 high levels of AA is important to you, then the Radeon RX 5600 is the winner, and very much so. (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 maximum amount of information (measured in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
