Compare any two graphics cards:
GeForce GTX 650 Ti 2GB vs GeForce GTX 660 Ti
IntroThe GeForce GTX 650 Ti 2GB features a clock speed of 928 MHz and a GDDR5 memory frequency of 1350 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is made up of 768 SPUs, 64 TAUs, and 16 ROPs.Compare that to the GeForce GTX 660 Ti, which uses a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 RAM works at a frequency of 1500 MHz on this specific card. It features 1344 SPUs as well as 112 Texture Address Units and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 660 Ti should in theory be much superior to the GeForce GTX 650 Ti 2GB overall. (explain)
Texel RateThe GeForce GTX 660 Ti should be much (more or less 73%) more effective at anisotropic filtering than the GeForce GTX 650 Ti 2GB. (explain)
Pixel RateThe GeForce GTX 660 Ti will be quite a bit (about 48%) more effective at FSAA than the GeForce GTX 650 Ti 2GB, and able to handle higher resolutions without slowing down too much. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core 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 processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
