Compare any two graphics cards:
GeForce 8800 GTS (G92) vs GeForce GTX 470
IntroThe GeForce 8800 GTS (G92) has a clock frequency of 650 MHz and a GDDR3 memory frequency of 970 MHz. It also makes use of a 256-bit memory bus, and uses a 65 nm design. It features 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare that to the GeForce GTX 470, which features GPU core speed of 607 MHz, and 1280 MB of GDDR5 memory set to run at 837 MHz through a 320-bit bus. It also features 448 SPUs, 56 Texture Address Units, and 40 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 470 should perform much faster than the GeForce 8800 GTS (G92) in general. (explain)
Texel RateThe GeForce 8800 GTS (G92) should be a lot (approximately 22%) better at texture filtering than the GeForce GTX 470. (explain)
Pixel RateThe GeForce GTX 470 is much (about 133%) more effective at AA than the GeForce 8800 GTS (G92), and capable of handling higher screen resolutions better. (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 maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total 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 in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
