GeForce GTX 470 vs GeForce GTX 660 Ti

Intro

The GeForce GTX 470 features a GPU core clock speed of 607 MHz, and the 1280 MB of GDDR5 RAM is set to run at 837 MHz through a 320-bit bus. It also features 448 Stream Processors, 56 TAUs, and 40 Raster Operation Units.

Compare those specs to the GeForce GTX 660 Ti, which comes with a GPU core clock speed of 915 MHz, and 2048 MB of GDDR5 memory running at 1500 MHz through a 192-bit bus. It also is comprised of 1344 Stream Processors, 112 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 660 Ti 150 Watts
GeForce GTX 470 215 Watts
Difference: 65 Watts (43%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 660 Ti will be 8% faster than the GeForce GTX 470 overall, because of its higher bandwidth. (explain)

GeForce GTX 660 Ti 144000 MB/sec
GeForce GTX 470 133920 MB/sec
Difference: 10080 (8%)

Texel Rate

The GeForce GTX 660 Ti should be a lot (more or less 201%) better at AF than the GeForce GTX 470. (explain)

GeForce GTX 660 Ti 102480 Mtexels/sec
GeForce GTX 470 33992 Mtexels/sec
Difference: 68488 (201%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 470 is superior to the GeForce GTX 660 Ti, but not by far. (explain)

GeForce GTX 470 24280 Mpixels/sec
GeForce GTX 660 Ti 21960 Mpixels/sec
Difference: 2320 (11%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
