Compare any two graphics cards:
GeForce GTX 570 vs GeForce GTX 650 Ti 2GB
IntroThe GeForce GTX 570 has a GPU clock speed of 732 MHz, and the 1280 MB of GDDR5 RAM runs at 950 MHz through a 320-bit bus. It also is made up of 480 Stream Processors, 60 Texture Address Units, and 40 ROPs.
Compare those specs to the GeForce GTX 650 Ti 2GB, which comes with a GPU core clock speed of 928 MHz, and 2048 MB of GDDR5 memory running at 1350 MHz through a 128-bit bus. It also is made up of 768 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 570 should perform much faster than the GeForce GTX 650 Ti 2GB overall. (explain)
Texel RateThe GeForce GTX 650 Ti 2GB is quite a bit (about 35%) better at texture filtering than the GeForce GTX 570. (explain)
Pixel RateThe GeForce GTX 570 is a lot (about 97%) better at AA than the GeForce GTX 650 Ti 2GB, and should be 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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it 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 anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
