Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs GeForce GT 320
IntroThe GeForce 8600 GT 1GB GDDR3 has a clock frequency of 540 MHz and a GDDR3 memory speed of 700 MHz. It also features a 128-bit bus, and makes use of a 80 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 ROPs.Compare all that to the GeForce GT 320, which has core clock speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 RAM. It features 72 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GT 320 should perform just a bit faster than the GeForce 8600 GT 1GB GDDR3 overall. (explain)
Texel RateThe GeForce GT 320 will be quite a bit (approximately 50%) more effective at texture filtering than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateBoth cards have the exact same pixel rate, so theoretically they should perform equally good at at AA, and be able to handle the same resolutions. (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 Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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.
