Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon HD 4830 512MB
IntroThe GeForce 8800 GTS (G80) 320MB features a clock speed of 513 MHz and a GDDR3 memory frequency of 792 MHz. It also features a 320-bit memory bus, and makes use of a 90 nm design. It features 96 SPUs, 48 Texture Address Units, and 20 Raster Operation Units.Compare all that to the Radeon HD 4830 512MB, which makes use of a 55 nm design. AMD has set the core frequency at 575 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this specific model. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 8800 GTS (G80) 320MB should in theory be a little bit superior to the Radeon HD 4830 512MB in general. (explain)
Texel RateThe GeForce 8800 GTS (G80) 320MB should be much (about 34%) more effective at texture filtering than the Radeon HD 4830 512MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 8800 GTS (G80) 320MB is the winner, though only just barely. (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 largest amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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 potential to get to the maximum fill rate.
