Compare any two graphics cards:
GeForce 8800 GT 256MB vs GeForce GT 430 (OEM)
IntroThe GeForce 8800 GT 256MB makes use of a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 RAM works at a speed of 700 MHz on this particular card. It features 112 SPUs as well as 56 Texture Address Units and 16 ROPs.
Compare those specs to the GeForce GT 430 (OEM), which uses a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this card. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce 8800 GT 256MB is 56% faster than the GeForce GT 430 (OEM) in general, due to its higher data rate. (explain)
Texel RateThe GeForce 8800 GT 256MB will be quite a bit (more or less 200%) better at texture filtering than the GeForce GT 430 (OEM). (explain)
Pixel RateThe GeForce 8800 GT 256MB is a lot (approximately 243%) faster with regards to full screen anti-aliasing than the GeForce GT 430 (OEM), and also should 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.
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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
