Compare any two graphics cards:
GeForce 8800 GT 1GB vs GeForce GT 430 1GB
IntroThe GeForce 8800 GT 1GB features a clock speed of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit memory bus, and uses a 65 nm design. It is comprised of 112 SPUs, 56 TAUs, and 16 Raster Operation Units.
Compare those specifications to the GeForce GT 430 1GB, which makes use of a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 RAM works at a speed of 900 MHz on this specific card. It features 96 SPUs as well as 16 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce 8800 GT 1GB should be 100% quicker than the GeForce GT 430 1GB overall, because of its greater data rate. (explain)
Texel RateThe GeForce 8800 GT 1GB will be much (about 200%) faster with regards to texture filtering than the GeForce GT 430 1GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 8800 GT 1GB is the winner, by far. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied in one second. This is worked out 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 applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 potential to reach the maximum fill rate.
