Compare any two graphics cards:
GeForce GTX 570 vs GeForce GTX 650 Ti
IntroThe GeForce GTX 570 comes with a GPU core clock speed of 732 MHz, and the 1280 MB of GDDR5 RAM is set to run at 950 MHz through a 320-bit bus. It also is made up of 480 SPUs, 60 TAUs, and 40 ROPs.
Compare that to the GeForce GTX 650 Ti, which has a GPU core clock speed of 928 MHz, and 1024 MB of GDDR5 RAM running at 1350 MHz through a 128-bit bus. It also features 768 Stream Processors, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 570 should be a lot faster than the GeForce GTX 650 Ti in general. (explain)
Texel RateThe GeForce GTX 650 Ti should be quite a bit (approximately 35%) more effective at texture filtering than the GeForce GTX 570. (explain)
Pixel RateThe GeForce GTX 570 is quite a bit (approximately 97%) faster with regards to full screen anti-aliasing than the GeForce GTX 650 Ti, and also should be able to handle higher screen resolutions better. (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 transferred across the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 are processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
