Compare any two graphics cards:
GeForce GTX 460 1GB vs GeForce GTX 660 Ti
IntroThe GeForce GTX 460 1GB has core speeds of 675 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.
Compare those specs to the GeForce GTX 660 Ti, which comes with a clock frequency of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 192-bit bus, and makes use of a 28 nm design. It is made up of 1344 SPUs, 112 TAUs, and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 660 Ti, in theory, should be quite a bit faster than the GeForce GTX 460 1GB in general. (explain)
Texel RateThe GeForce GTX 660 Ti is a lot (more or less 171%) more effective at AF than the GeForce GTX 460 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 660 Ti is the winner, but it probably won't make a huge difference. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 are processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
