GeForce GTX 560 vs Radeon RX 480 4GB

Intro

Compare those specs to the Radeon RX 480 4GB, which comes with GPU clock speed of 1120 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 256-bit bus. It also features 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon RX 480 4GB should be 79% faster than the GeForce GTX 560 overall, due to its greater data rate. (explain)

Radeon RX 480 4GB		229376 MB/sec
GeForce GTX 560		128128 MB/sec
	Difference: 101248 (79%)

Texel Rate

The Radeon RX 480 4GB will be much (approximately 256%) more effective at AF than the GeForce GTX 560. (explain)

Radeon RX 480 4GB		161280 Mtexels/sec
GeForce GTX 560		45360 Mtexels/sec
	Difference: 115920 (256%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 480 4GB is a better choice, by far. (explain)

Radeon RX 480 4GB		35840 Mpixels/sec
GeForce GTX 560		25920 Mpixels/sec
	Difference: 9920 (38%)

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 (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on 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 bandwidth is, the lower the ability to reach the max fill rate.
