Compare any two graphics cards:
GeForce 8800 GT 1GB vs GeForce GT 430 1GB
IntroThe GeForce 8800 GT 1GB makes use of a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 memory works at a speed of 900 MHz on this card. It features 112 SPUs as well as 56 TAUs and 16 ROPs.
Compare all that to the GeForce GT 430 1GB, which has clock speeds of 700 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce 8800 GT 1GB should in theory be quite a bit better than the GeForce GT 430 1GB in general. (explain)
Texel RateThe GeForce 8800 GT 1GB will be quite a bit (about 200%) faster with regards to AF than the GeForce GT 430 1GB. (explain)
Pixel RateThe GeForce 8800 GT 1GB should be much (about 243%) faster with regards to full screen anti-aliasing than the GeForce GT 430 1GB, and also will be capable of handling higher 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.
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 maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of 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 AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
