Radeon R9 280 vs Radeon RX 480

Intro

The Radeon R9 280 comes with a core clock speed of 933 MHz and a GDDR5 memory speed of 1250 MHz. It also uses a 384-bit memory bus, and makes use of a 28 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the Radeon RX 480, which comes with GPU core speed of 1120 MHz, and 8192 MB of GDDR5 RAM set to run at 2000 MHz through a 256-bit bus. It also is comprised of 2304 SPUs, 144 TAUs, and 32 ROPs.

Difference: 100 Watts (67%)

Memory Bandwidth

Theoretically, the Radeon RX 480 should perform a small bit faster than the Radeon R9 280 in general. (explain)

Radeon RX 480 262144 MB/sec
Radeon R9 280 240000 MB/sec
Difference: 22144 (9%)

Texel Rate

The Radeon RX 480 should be much (approximately 54%) more effective at texture filtering than the Radeon R9 280. (explain)

Radeon RX 480 161280 Mtexels/sec
Radeon R9 280 104496 Mtexels/sec
Difference: 56784 (54%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 480 is a better choice, but it probably won't make a huge difference. (explain)

Radeon RX 480 35840 Mpixels/sec
Radeon R9 280 29856 Mpixels/sec
Difference: 5984 (20%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, 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 number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
