GeForce GTX 660 Ti vs Radeon RX 480

Intro

Compare all of that to the Radeon RX 480, which has a clock frequency of 1120 MHz and a GDDR5 memory frequency of 2000 MHz. It also uses a 256-bit memory bus, and makes use of a 14 nm design. It is comprised of 2304 SPUs, 144 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Radeon RX 480 should theoretically be quite a bit better than the GeForce GTX 660 Ti overall. (explain)

Radeon RX 480		262144 MB/sec
GeForce GTX 660 Ti		144000 MB/sec
	Difference: 118144 (82%)

Texel Rate

The Radeon RX 480 is a lot (more or less 57%) more effective at anisotropic filtering than the GeForce GTX 660 Ti. (explain)

Radeon RX 480		161280 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 58800 (57%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 480 is the winner, by a large margin. (explain)

Radeon RX 480		35840 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 13880 (63%)

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 maximum amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
