Radeon RX 460 2GB vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which makes use of a 14 nm design. AMD has clocked the core speed at 1175 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this particular card. It features 1024 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
Radeon RX 560		80 Watts
	Difference: 5 Watts (7%)

Memory Bandwidth

Theoretically, the Radeon RX 560 should be just a bit faster than the Radeon RX 460 2GB overall. (explain)

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

Texel Rate

The Radeon RX 560 is much (approximately 23%) better at anisotropic filtering than the Radeon RX 460 2GB. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 14160 (23%)

Pixel Rate

The Radeon RX 560 will be a bit (approximately 8%) more effective at FSAA than the Radeon RX 460 2GB, and also should be able to handle higher resolutions while still performing well. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon RX 460 2GB		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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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