Compare any two graphics cards:
GeForce 8400 GS 512MB vs GeForce GT 430 (OEM)
IntroThe GeForce 8400 GS 512MB has core speeds of 650 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 16 SPUs as well as 8 Texture Address Units and 4 ROPs.
Compare those specifications to the GeForce GT 430 (OEM), which comes with a core clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It features 96 SPUs, 16 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GT 430 (OEM) is 350% quicker than the GeForce 8400 GS 512MB in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce GT 430 (OEM) will be quite a bit (approximately 115%) better at anisotropic filtering than the GeForce 8400 GS 512MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GT 430 (OEM) is superior to the GeForce 8400 GS 512MB, though not 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 (in units of MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core clock 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 applied in a second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate 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 filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
