Compare any two graphics cards:
GeForce 9600 GT 1GB vs GeForce GT 430 1GB
IntroThe GeForce 9600 GT 1GB comes with 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 comprised of 64 Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.
Compare those specifications to the GeForce GT 430 1GB, which has a GPU core clock speed of 700 MHz, and 1024 MB of GDDR3 memory running at 900 MHz through a 128-bit bus. It also is comprised of 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce 9600 GT 1GB should in theory be much superior to the GeForce GT 430 1GB in general. (explain)
Texel RateThe GeForce 9600 GT 1GB should be much (about 86%) more effective at AF than the GeForce GT 430 1GB. (explain)
Pixel RateThe GeForce 9600 GT 1GB should be a lot (approximately 271%) more effective at anti-aliasing than the GeForce GT 430 1GB, and also able to handle higher screen resolutions while still performing well. (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 data (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per 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 drawing the pixels (image) on the screen. The actual pixel rate also depends on many 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.
