	Difference: 30 Watts (25%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 470 4GB is 47% quicker than the GeForce GTX 660 Ti in general, because of its higher bandwidth. (explain)

Radeon RX 470 4GB		211200 MB/sec
GeForce GTX 660 Ti		144000 MB/sec
	Difference: 67200 (47%)

Texel Rate

The Radeon RX 470 4GB is a bit (about 16%) more effective at texture filtering than the GeForce GTX 660 Ti. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 16048 (16%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 470 4GB is a better choice, by far. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 7672 (35%)

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 largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one 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 - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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 get to the max fill rate.
