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

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 570 should theoretically be a lot superior to the GeForce GTX 650 Ti overall. (explain)
Texel RateThe GeForce GTX 650 Ti will be a lot (approximately 35%) more effective at anisotropic filtering than the GeForce GTX 570. (explain)
Pixel RateThe GeForce GTX 570 is a lot (approximately 97%) more effective at FSAA than the GeForce GTX 650 Ti, 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 (measured in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
