Compare any two graphics cards:
GeForce 8400 GS 512MB vs GeForce 9600 GT 1GB
IntroThe GeForce 8400 GS 512MB makes use of a 80 nm design. nVidia has set the core frequency at 650 MHz. The DDR2 memory works at a frequency of 400 MHz on this particular model. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.
Compare those specifications to the GeForce 9600 GT 1GB, which uses a 65/55 nm design. nVidia has set the core frequency at 650 MHz. The GDDR3 RAM works at a speed of 900 MHz on this card. It features 64 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce 9600 GT 1GB should perform much faster than the GeForce 8400 GS 512MB overall. (explain)
Texel RateThe GeForce 9600 GT 1GB is a lot (approximately 300%) better at AF than the GeForce 8400 GS 512MB. (explain)
Pixel RateThe GeForce 9600 GT 1GB should be much (more or less 300%) better at AA than the GeForce 8400 GS 512MB, and able to handle higher screen 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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number 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 drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
