Compare any two graphics cards:
GeForce GTX 260 Core 216 vs GeForce GTX 660
IntroThe GeForce GTX 260 Core 216 comes with a core clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also makes use of a 448-bit memory bus, and uses a 65 nm design. It is comprised of 216 SPUs, 72 TAUs, and 28 ROPs.Compare that to the GeForce GTX 660, which features a clock frequency of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also features a 192-bit bus, and uses a 28 nm design. It is made up of 960 SPUs, 80 TAUs, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 660 should theoretically be a lot superior to the GeForce GTX 260 Core 216 in general. (explain)
Texel RateThe GeForce GTX 660 should be quite a bit (about 89%) more effective at texture filtering than the GeForce GTX 260 Core 216. (explain)
Pixel RateThe GeForce GTX 660 will be a lot (more or less 46%) more effective at AA than the GeForce GTX 260 Core 216, and should be capable of handling higher resolutions while still performing well. (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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock 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 processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
