Compare any two graphics cards:
GeForce 8600 GT 256MB DDR2 vs Radeon HD 5450
IntroThe GeForce 8600 GT 256MB DDR2 has a GPU core clock speed of 540 MHz, and the 256 MB of DDR2 RAM is set to run at 400 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 Texture Address Units, and 8 ROPs.Compare all that to the Radeon HD 5450, which comes with GPU core speed of 650 MHz, and 512 MB of DDR3 RAM running at 800 MHz through a 64-bit bus. It also features 80(16x5) Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same bandwidth, so theoretically they should perform the same. (explain)
Texel RateThe GeForce 8600 GT 256MB DDR2 should be quite a bit (approximately 66%) faster with regards to AF than the Radeon HD 5450. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 8600 GT 256MB DDR2 is a better choice, 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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling 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 chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
