Radeon RX 470 vs Radeon RX 590

Intro

The Radeon RX 470 uses a 14 nm design. AMD has set the core frequency at 926 MHz. The GDDR5 RAM is set to run at a frequency of 1650 MHz on this particular card. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Compare those specs to the Radeon RX 590, which makes use of a 12 nm design. AMD has set the core frequency at 1469 MHz. The GDDR5 memory is set to run at a frequency of 2000 MHz on this particular model. It features 2304 SPUs along with 144 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470 120 Watts
Radeon RX 590 175 Watts
Difference: 55 Watts (46%)

Memory Bandwidth

The Radeon RX 590, in theory, should be much faster than the Radeon RX 470 overall. (explain)

Radeon RX 590 262144 MB/sec
Radeon RX 470 211200 MB/sec
Difference: 50944 (24%)

Texel Rate

The Radeon RX 590 is quite a bit (about 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 much (more or less 59%) more effective at AA than the Radeon RX 470, and should be capable of handling higher screen resolutions without slowing down too much. (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: Bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units by the core 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
