Compare any two graphics cards:
GeForce GTX 570 vs GeForce GTX 650 Ti
IntroThe GeForce GTX 570 comes with a GPU 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 comprised of 480 SPUs, 60 Texture Address Units, and 40 ROPs.
Compare all of that to the GeForce GTX 650 Ti, which features a clock frequency of 928 MHz and a GDDR5 memory frequency of 1350 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 768 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 570 will be 76% quicker than the GeForce GTX 650 Ti in general, due to its higher data rate. (explain)
Texel RateThe GeForce GTX 650 Ti should be much (approximately 35%) faster with regards to texture filtering than the GeForce GTX 570. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 570 is superior to the GeForce GTX 650 Ti, by far. (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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 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 higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
