Compare any two graphics cards:
GeForce GTX 650 Ti 2GB vs GeForce GTX 780 Ti
IntroThe GeForce GTX 650 Ti 2GB features clock speeds of 928 MHz on the GPU, and 1350 MHz on the 2048 MB of GDDR5 RAM. It features 768 SPUs along with 64 TAUs and 16 ROPs.Compare all of that to the GeForce GTX 780 Ti, which has clock speeds of 875 MHz on the GPU, and 1750 MHz on the 3072 MB of GDDR5 memory. It features 2880 SPUs as well as 240 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 780 Ti should theoretically be much superior to the GeForce GTX 650 Ti 2GB overall. (explain)
Texel RateThe GeForce GTX 780 Ti will be a lot (about 254%) better at anisotropic filtering than the GeForce GTX 650 Ti 2GB. (explain)
Pixel RateThe GeForce GTX 780 Ti will be quite a bit (about 183%) more effective at anti-aliasing than the GeForce GTX 650 Ti 2GB, and should be able to handle higher screen 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 information (in units of MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
