Compare any two graphics cards:
GeForce GTX 570 vs GeForce GTX 660 Ti
IntroThe GeForce GTX 570 has a clock frequency of 732 MHz and a GDDR5 memory speed of 950 MHz. It also uses a 320-bit memory bus, and makes use of a 40 nm design. It is comprised of 480 SPUs, 60 Texture Address Units, and 40 ROPs.Compare those specifications to the GeForce GTX 660 Ti, which has a core clock speed of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 192-bit memory bus, and uses a 28 nm design. It is made up of 1344 SPUs, 112 TAUs, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 570 should in theory perform just a bit faster than the GeForce GTX 660 Ti overall. (explain)
Texel RateThe GeForce GTX 660 Ti should be a lot (approximately 133%) better at texture filtering than the GeForce GTX 570. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 570 is the winner, 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 Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.

Guys, Im do 3D Rendering with CUDA GPGPU. I heard that GTX6** are bad for computing. I use mostly Blender Cycles or OctaneRender. I do play latest games too.How bad is the GTX660 vs GTX570. Please anyone. I have to buy either of the two
