Compare any two graphics cards:
GeForce GTX 650 Ti vs GeForce GTX 660 Ti
IntroThe GeForce GTX 650 Ti makes use of a 28 nm design. nVidia has clocked the core speed at 928 MHz. The GDDR5 RAM runs at a speed of 1350 MHz on this model. It features 768 SPUs along with 64 TAUs and 16 Rasterization Operator Units.
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 memory is set to run at a frequency of 1500 MHz on this specific card. It features 1344 SPUs as well as 112 Texture Address Units and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 660 Ti should in theory be much superior to the GeForce GTX 650 Ti in general. (explain)
Texel RateThe GeForce GTX 660 Ti should be much (more or less 73%) faster with regards to anisotropic filtering than the GeForce GTX 650 Ti. (explain)
Pixel RateThe GeForce GTX 660 Ti will be a lot (about 48%) better at FSAA than the GeForce GTX 650 Ti, and also able to handle higher 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.
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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR 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 number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
