Compare any two graphics cards:
GeForce GTX 285 1GB vs Radeon HD 5830
IntroThe GeForce GTX 285 1GB comes with a core clock frequency of 648 MHz and a GDDR3 memory frequency of 1242 MHz. It also features a 512-bit memory bus, and uses a 55 nm design. It features 240 SPUs, 80 TAUs, and 32 Raster Operation Units.Compare all of that to the Radeon HD 5830, which uses a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this specific card. It features 1120(224x5) SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 285 1GB should in theory be a lot superior to the Radeon HD 5830 overall. (explain)
Texel RateThe GeForce GTX 285 1GB will be a small bit (approximately 16%) better at texture filtering than the Radeon HD 5830. (explain)
Pixel RateThe GeForce GTX 285 1GB should be much (about 62%) more effective at AA than the Radeon HD 5830, and should be capable of handling 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 largest amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core 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 can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
