Compare any two graphics cards:
GeForce GTX 260 vs GeForce GTX 660 Ti
IntroThe GeForce GTX 260 features a clock speed of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also features a 448-bit bus, and makes use of a 65 nm design. It is comprised of 192 SPUs, 64 Texture Address Units, and 28 ROPs.Compare those specifications to the GeForce GTX 660 Ti, which features core speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1344 SPUs along with 112 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 660 Ti should in theory be much better than the GeForce GTX 260 in general. (explain)
Texel RateThe GeForce GTX 660 Ti should be much (about 178%) better at texture filtering than the GeForce GTX 260. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 660 Ti is superior to the GeForce GTX 260, and very much so. (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 largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
