Compare any two graphics cards:
GeForce GTX 460 2GB vs GeForce GTX 660 Ti
IntroThe GeForce GTX 460 2GB features clock speeds of 675 MHz on the GPU, and 900 MHz on the 2048 MB of GDDR5 memory. It features 336 SPUs as well as 56 TAUs and 32 ROPs.
Compare those specs to the GeForce GTX 660 Ti, which has a core clock speed of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 192-bit bus, and makes use of a 28 nm design. It is comprised of 1344 SPUs, 112 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 660 Ti should be quite a bit faster than the GeForce GTX 460 2GB in general. (explain)
Texel RateThe GeForce GTX 660 Ti is quite a bit (about 171%) better at anisotropic filtering than the GeForce GTX 460 2GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 660 Ti is a better choice, but not by far. (explain)
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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
