Radeon RX 460 vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which uses a 14 nm design. AMD has clocked the core speed at 1175 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this specific model. It features 1024 SPUs as well as 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

Theoretically speaking, the Radeon RX 560 should be 2% quicker than the Radeon RX 460 overall, because of its higher data rate. (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%) 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

The Radeon RX 560 should be a small bit (about 8%) better at FSAA than the Radeon RX 460, and also should be able to handle higher screen resolutions without slowing down too much. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses 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 processed per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at 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 the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
