Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon HD 3850 1GB
IntroThe GeForce 8600 GT 512MB DDR2 uses a 80 nm design. nVidia has set the core frequency at 540 MHz. The DDR2 RAM is set to run at a frequency of 400 MHz on this specific card. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 3850 1GB, which has GPU core speed of 668 MHz, and 1024 MB of GDDR3 RAM set to run at 828 MHz through a 256-bit bus. It also is comprised of 320(64x5) Stream Processors, 16 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 3850 1GB should theoretically be a lot better than the GeForce 8600 GT 512MB DDR2 overall. (explain)
Texel RateThe Radeon HD 3850 1GB will be quite a bit (approximately 24%) faster with regards to texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 3850 1GB is superior to the GeForce 8600 GT 512MB DDR2, 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant 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 maximum fill rate.
