GeForce GTX 260 vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which makes use of a 14 nm design. AMD has clocked the core speed at 1175 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this card. It features 1024 SPUs along with 64 TAUs and 16 ROPs.

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

In theory, the Radeon RX 560 is 3% quicker than the GeForce GTX 260 overall, because of its greater data rate. (explain)

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

Texel Rate

The Radeon RX 560 is a lot (approximately 104%) more effective at texture 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 using a high screen resolution is important to you, then the Radeon RX 560 is a better choice, 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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported over 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 RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
