Radeon R7 260X vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which has clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 1024 SPUs along with 64 Texture Address Units and 16 ROPs.

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

The Radeon RX 560 should theoretically perform a small bit faster than the Radeon R7 260X overall. (explain)

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

Texel Rate

The Radeon RX 560 will be a lot (more or less 22%) better at texture 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 using lots of anti-aliasing is important to you, then the Radeon RX 560 is superior to the Radeon R7 260X, though not by far. (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 largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video 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 most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core 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 fill rate is also dependant 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.
