Compare any two graphics cards:
GeForce 9600 GT 1GB vs GeForce GT 430 1GB
IntroThe GeForce 9600 GT 1GB features a GPU core speed of 650 MHz, and the 1024 MB of GDDR3 RAM is set to run at 900 MHz through a 256-bit bus. It also is made up of 64 Stream Processors, 32 TAUs, and 16 Raster Operation Units.
Compare all of that to the GeForce GT 430 1GB, which uses a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR3 memory works at a frequency of 900 MHz on this specific card. It features 96 SPUs along with 16 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce 9600 GT 1GB should in theory be quite a bit superior to the GeForce GT 430 1GB in general. (explain)
Texel RateThe GeForce 9600 GT 1GB is much (more or less 86%) more effective at texture filtering than the GeForce GT 430 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce 9600 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 max amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video 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 number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
