Radeon R7 260X vs Radeon RX 560

Intro

Compare all that to the Radeon RX 560, which has a clock speed of 1175 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 128-bit memory bus, and makes use of a 14 nm design. It is comprised of 1024 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
Radeon R7 260X		115 Watts
	Difference: 35 Watts (44%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 560 should be 10% faster than the Radeon R7 260X in general, because of its greater data rate. (explain)

Radeon RX 560		114688 MB/sec
Radeon R7 260X		104000 MB/sec
	Difference: 10688 (10%)

Texel Rate

The Radeon RX 560 will be much (more or less 22%) more effective at anisotropic filtering than the Radeon R7 260X. (explain)

Radeon RX 560		75200 Mtexels/sec
Radeon R7 260X		61600 Mtexels/sec
	Difference: 13600 (22%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 560 is a better choice, but it probably won't make a huge difference. (explain)

Radeon RX 560		18800 Mpixels/sec
Radeon R7 260X		17600 Mpixels/sec
	Difference: 1200 (7%)

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 max amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the 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 the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
