Radeon R9 280 vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which has a core clock frequency of 1375 MHz and a GDDR6 memory frequency of 1500 MHz. It also makes use of a 192-bit bus, and makes use of a 7 nm design. It features 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

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

In theory, the Radeon RX 5600 is 23% quicker than the Radeon R9 280 in general, because of its greater data rate. (explain)

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

Texel Rate

The Radeon RX 5600 should be a lot (approximately 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

The Radeon RX 5600 is quite a bit (more or less 195%) more effective at FSAA than the Radeon R9 280, and able to handle higher resolutions while still performing well. (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 max amount of data (counted in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
