Compare any two graphics cards:
GeForce GTX 570 vs GeForce GTX 650 Ti 2GB
IntroThe GeForce GTX 570 makes use of a 40 nm design. nVidia has set the core frequency at 732 MHz. The GDDR5 RAM is set to run at a speed of 950 MHz on this specific model. It features 480 SPUs along with 60 TAUs and 40 Rasterization Operator Units.
Compare those specs to the GeForce GTX 650 Ti 2GB, which makes use of a 28 nm design. nVidia has set the core speed at 928 MHz. The GDDR5 memory works at a speed of 1350 MHz on this model. It features 768 SPUs as well as 64 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 570 should be a lot faster than the GeForce GTX 650 Ti 2GB overall. (explain)
Texel RateThe GeForce GTX 650 Ti 2GB should be a lot (about 35%) more effective at anisotropic filtering than the GeForce GTX 570. (explain)
Pixel RateThe GeForce GTX 570 should be a lot (about 97%) better at anti-aliasing than the GeForce GTX 650 Ti 2GB, and also 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.
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 max amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
