Compare any two graphics cards:
GeForce GTX 285 1GB vs Radeon HD 5830
IntroThe GeForce GTX 285 1GB makes use of a 55 nm design. nVidia has set the core frequency at 648 MHz. The GDDR3 memory is set to run at a frequency of 1242 MHz on this specific card. It features 240 SPUs as well as 80 TAUs and 32 ROPs.Compare those specifications to the Radeon HD 5830, which comes with a core clock frequency of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 256-bit memory bus, and uses a 40 nm design. It features 1120(224x5) SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 285 1GB should be a lot faster than the Radeon HD 5830 in general. (explain)
Texel RateThe GeForce GTX 285 1GB should be a small bit (approximately 16%) better at AF than the Radeon HD 5830. (explain)
Pixel RateThe GeForce GTX 285 1GB should be a lot (more or less 62%) more effective at FSAA than the Radeon HD 5830, and also should be able to handle higher resolutions more effectively. (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 MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should 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 processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
