Radeon RX 470 vs Radeon RX 590

Intro

The Radeon RX 470 comes with a core clock frequency of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also features a 256-bit memory bus, and uses a 14 nm design. It features 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Compare that to the Radeon RX 590, which comes with a core clock speed of 1469 MHz and a GDDR5 memory speed of 2000 MHz. It also makes use of a 256-bit memory bus, and uses a 12 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

The Radeon RX 590 will be a lot (approximately 78%) better at anisotropic filtering than the Radeon RX 470. (explain)

Radeon RX 590 211536 Mtexels/sec
Radeon RX 470 118528 Mtexels/sec
Difference: 93008 (78%)

Pixel Rate

The Radeon RX 590 should be quite a bit (more or less 59%) better at full screen anti-aliasing than the Radeon RX 470, and will be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 590 47008 Mpixels/sec
Radeon RX 470 29632 Mpixels/sec
Difference: 17376 (59%)

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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 ability to reach the maximum fill rate.
