Compare any two graphics cards:
GeForce GTX 570 vs GeForce GTX 650 Ti
IntroThe GeForce GTX 570 uses a 40 nm design. nVidia has clocked the core frequency at 732 MHz. The GDDR5 RAM works at a speed of 950 MHz on this specific card. It features 480 SPUs along with 60 Texture Address Units and 40 Rasterization Operator Units.
Compare those specifications to the GeForce GTX 650 Ti, which features clock speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 RAM. It features 768 SPUs along with 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 570, in theory, should be much faster than the GeForce GTX 650 Ti overall. (explain)
Texel RateThe GeForce GTX 650 Ti is a lot (approximately 35%) more effective at AF than the GeForce GTX 570. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 570 is superior to the GeForce GTX 650 Ti, by a large margin. (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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 are applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
