Compare any two graphics cards:
GeForce 9600 GT 1GB vs GeForce GT 430 1GB
IntroThe GeForce 9600 GT 1GB has core clock speeds of 650 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. It features 64 SPUs along with 32 Texture Address Units and 16 ROPs.
Compare those specifications to the GeForce GT 430 1GB, which comes with a core clock speed of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 128-bit bus, and uses a 40 nm design. It is comprised of 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce 9600 GT 1GB will be 100% faster than the GeForce GT 430 1GB in general, because of its greater data rate. (explain)
Texel RateThe GeForce 9600 GT 1GB should be much (more or less 86%) more effective at AF than the GeForce GT 430 1GB. (explain)
Pixel RateThe GeForce 9600 GT 1GB should be much (approximately 271%) more effective at full screen anti-aliasing than the GeForce GT 430 1GB, and will be capable of handling higher resolutions without slowing down too much. (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 transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
