GeForce GTX 260 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which has a GPU core clock speed of 1175 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is comprised of 1024 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
GeForce GTX 260		182 Watts
	Difference: 102 Watts (128%)

Memory Bandwidth

The Radeon RX 560, in theory, should perform a small bit faster than the GeForce GTX 260 in general. (explain)

Radeon RX 560		114688 MB/sec
GeForce GTX 260		111888 MB/sec
	Difference: 2800 (3%)

Texel Rate

The Radeon RX 560 should be a lot (more or less 104%) faster with regards to anisotropic filtering than the GeForce GTX 260. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 260		36864 Mtexels/sec
	Difference: 38336 (104%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 560 is the winner, though not by far. (explain)

Radeon RX 560		18800 Mpixels/sec
GeForce GTX 260		16128 Mpixels/sec
	Difference: 2672 (17%)

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 information (in units of MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at 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 the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
