Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GT 220 GDDR3
IntroThe GeForce 8600 GT 512MB DDR2 makes use of a 80 nm design. nVidia has set the core speed at 540 MHz. The DDR2 RAM runs at a speed of 400 MHz on this model. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare all that to the GeForce GT 220 GDDR3, which features GPU core speed of 625 MHz, and 512 MB of GDDR3 memory running at 1012 MHz through a 128-bit bus. It also is comprised of 48 Stream Processors, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GT 220 GDDR3 should perform quite a bit faster than the GeForce 8600 GT 512MB DDR2 overall. (explain)
Texel RateThe GeForce GT 220 GDDR3 will be a little bit (more or less 16%) more effective at anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GT 220 GDDR3 is superior to the GeForce 8600 GT 512MB DDR2, but only just. (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 data (counted in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
