Compare any two graphics cards:
GeForce GT 130 vs GeForce GTX 660
IntroThe GeForce GT 130 uses a 55 nm design. nVidia has clocked the core frequency at 500 MHz. The DDR2 memory is set to run at a frequency of 250 MHz on this particular card. It features 48 SPUs along with 24 TAUs and 16 Rasterization Operator Units.Compare those specifications to the GeForce GTX 660, which has a clock speed of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 192-bit bus, and makes use of a 28 nm design. It features 960 SPUs, 80 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 660 should be quite a bit faster than the GeForce GT 130 overall. (explain)
Texel RateThe GeForce GTX 660 is much (about 553%) more effective at texture filtering than the GeForce GT 130. (explain)
Pixel RateThe GeForce GTX 660 will be a lot (more or less 194%) better at AA than the GeForce GT 130, and will be able to handle higher resolutions without slowing down too much. (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

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core 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 the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
