Radeon RX 460 vs Radeon RX 560

Intro

The Radeon RX 460 features a core clock speed of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit bus, and uses a 14 nm design. It features 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Compare all that to the Radeon RX 560, which comes with GPU clock speed of 1175 MHz, and 4096 MB of GDDR5 RAM set to run at 7000 MHz through a 128-bit bus. It also is comprised of 1024 SPUs, 64 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 75 Watts
Radeon RX 560 80 Watts
Difference: 5 Watts (7%)

Memory Bandwidth

The Radeon RX 560 should theoretically be a bit faster than the Radeon RX 460 in general. (explain)

Radeon RX 560 114688 MB/sec
Radeon RX 460 112000 MB/sec
Difference: 2688 (2%)

Texel Rate

The Radeon RX 560 is quite a bit (more or less 23%) more effective at anisotropic filtering than the Radeon RX 460. (explain)

Radeon RX 560 75200 Mtexels/sec
Radeon RX 460 61040 Mtexels/sec
Difference: 14160 (23%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 560 is a better choice, though only just barely. (explain)

Radeon RX 560 18800 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 1360 (8%)

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 max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
