Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs GeForce GT 430 1GB
IntroThe GeForce 8600 GT 256MB GDDR3 makes use of a 80 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 RAM works at a frequency of 700 MHz on this specific card. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.
Compare those specs to the GeForce GT 430 1GB, which features a GPU core clock speed of 700 MHz, and 1024 MB of GDDR3 RAM set to run at 900 MHz through a 128-bit bus. It also features 96 SPUs, 16 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GT 430 1GB should in theory perform much faster than the GeForce 8600 GT 256MB GDDR3 overall. (explain)
Texel RateThe GeForce GT 430 1GB should be a lot (about 30%) more effective at texture filtering than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateThe GeForce 8600 GT 256MB GDDR3 will be quite a bit (approximately 54%) more effective at AA than the GeForce GT 430 1GB, and should be able to handle higher 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 data (in units of megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher 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 write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
