Radeon RX 460 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which makes use of a 14 nm design. AMD has set the core speed at 1175 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this model. It features 1024 SPUs along with 64 Texture Address Units 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, the Radeon RX 560 should 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 should be much (more or less 23%) better at texture 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 will be a bit (approximately 8%) more effective at full screen anti-aliasing than the Radeon RX 460, and also will be capable of handling higher 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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
