Compare any two graphics cards:
GeForce 8800 GT 1GB vs GeForce GT 430 1GB
IntroThe GeForce 8800 GT 1GB features clock speeds of 600 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. It features 112 SPUs along with 56 TAUs and 16 Rasterization Operator Units.
Compare all of that to the GeForce GT 430 1GB, which comes with a clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is made up of 96 SPUs, 16 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce 8800 GT 1GB should in theory be quite a bit superior to the GeForce GT 430 1GB in general. (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 RateThe GeForce 8800 GT 1GB will be much (about 243%) faster with regards to AA than the GeForce GT 430 1GB, and capable of handling higher screen resolutions more effectively. (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 largest amount of information (measured in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units 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 per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video 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 - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
