Radeon RX 460 vs Radeon RX 560

Intro

The Radeon RX 460 has a GPU core clock speed of 1090 MHz, and the 4096 MB of GDDR5 memory is set to run at 1750 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Compare that to the Radeon RX 560, which features GPU core speed of 1175 MHz, and 4096 MB of GDDR5 RAM running at 7000 MHz through a 128-bit bus. It also is made up of 1024 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

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

In theory, the Radeon RX 560 will be 2% quicker than the Radeon RX 460 in general, because of its higher bandwidth. (explain)

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

Texel Rate

The Radeon RX 560 is much (more or less 23%) better 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

The Radeon RX 560 is just a bit (about 8%) faster with regards to anti-aliasing than the Radeon RX 460, and should be able to handle higher screen resolutions better. (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 largest amount of data (in units of MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
