Radeon RX 480 vs Radeon RX 590

Intro

The Radeon RX 480 has core clock speeds of 1120 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2304 SPUs along with 144 TAUs and 32 ROPs.

Compare that to the Radeon RX 590, which uses a 12 nm design. AMD has clocked the core speed at 1469 MHz. The GDDR5 memory is set to run at a speed of 2000 MHz on this specific model. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 480 150 Watts
Radeon RX 590 175 Watts
Difference: 25 Watts (17%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Radeon RX 590 should be much (approximately 31%) better at anisotropic filtering than the Radeon RX 480. (explain)

Radeon RX 590 211536 Mtexels/sec
Radeon RX 480 161280 Mtexels/sec
Difference: 50256 (31%)

Pixel Rate

The Radeon RX 590 is quite a bit (about 31%) better at FSAA than the Radeon RX 480, and also will be capable of handling higher screen resolutions better. (explain)

Radeon RX 590 47008 Mpixels/sec
Radeon RX 480 35840 Mpixels/sec
Difference: 11168 (31%)

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 largest amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 applied per second. This figure is worked out 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one 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 calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
