Radeon RX 460 vs Radeon RX 560

Intro

The Radeon RX 460 comes with core speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs along with 56 TAUs and 16 ROPs.

Compare those specs to the Radeon RX 560, which has a clock speed of 1175 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit memory bus, and makes use of a 14 nm design. It 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

As far as performance goes, the Radeon RX 560 should in theory be a little bit superior to the Radeon RX 460 overall. (explain)

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

Texel Rate

The Radeon RX 560 should be quite a bit (approximately 23%) more effective at AF than the Radeon RX 460. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 560 is the winner, not by a very large margin though. (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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one 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 the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
