Radeon R9 280 vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which uses a 7 nm design. AMD has clocked the core frequency at 1375 MHz. The GDDR6 memory runs at a speed of 1500 MHz on this particular card. It features 2048 SPUs along with 128 TAUs and 64 ROPs.

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

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 will be 23% quicker than the Radeon R9 280 in general, due to its greater bandwidth. (explain)

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

Texel Rate

The Radeon RX 5600 will be quite a bit (more or less 68%) faster with regards to 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 much (about 195%) more effective at FSAA than the Radeon R9 280, and will be capable of handling higher resolutions better. (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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, the result 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 anti-aliasing, High Dynamic Range and high resolutions.

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

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