Compare any two graphics cards:
GeForce 8800 GT 1GB vs GeForce GT 430 1GB
IntroThe GeForce 8800 GT 1GB features a clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 256-bit memory bus, and makes use of a 65 nm design. It is made up of 112 SPUs, 56 TAUs, and 16 ROPs.
Compare that to the GeForce GT 430 1GB, which has GPU core speed of 700 MHz, and 1024 MB of GDDR3 memory set to run at 900 MHz through a 128-bit bus. It also is comprised of 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce 8800 GT 1GB, in theory, should perform quite a bit faster than the GeForce GT 430 1GB overall. (explain)
Texel RateThe GeForce 8800 GT 1GB will be a lot (more or less 200%) better at texture filtering than the GeForce GT 430 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 8800 GT 1GB is a better choice, 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: Bandwidth is the max amount of data (measured in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
