Radeon R7 260X vs Radeon RX 560

Intro

Compare all of that 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 speed of 1750 MHz on this specific model. 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 560		80 Watts
Radeon R7 260X		115 Watts
	Difference: 35 Watts (44%)

Memory Bandwidth

Performance-wise, the Radeon RX 560 should theoretically be a bit superior to the Radeon R7 260X in general. (explain)

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

Texel Rate

The Radeon RX 560 should be quite a bit (more or less 22%) faster with regards to AF 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 lots of anti-aliasing is important to you, then the Radeon RX 560 is a better choice, not by a very large margin though. (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: Bandwidth is the max amount of data (in units of MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

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