Compare any two graphics cards:
GeForce GTX 460 2GB vs GeForce GTX 660
IntroThe GeForce GTX 460 2GB has core 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 Texture Address Units and 32 ROPs.Compare those specifications to the GeForce GTX 660, which comes with clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 960 SPUs along with 80 TAUs and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 660 should theoretically be quite a bit better than the GeForce GTX 460 2GB overall. (explain)
Texel RateThe GeForce GTX 660 will be a lot (more or less 107%) faster with regards to texture filtering than the GeForce GTX 460 2GB. (explain)
Pixel RateThe GeForce GTX 660 will be just a bit (more or less 9%) more effective at anti-aliasing than the GeForce GTX 460 2GB, and also able to handle higher screen resolutions while still performing well. (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 Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
