Compare any two graphics cards:
GeForce GTX 280 vs Radeon HD 5830
IntroThe GeForce GTX 280 makes use of a 65 nm design. nVidia has clocked the core speed at 602 MHz. The GDDR3 memory is set to run at a frequency of 1107 MHz on this particular card. It features 240 SPUs along with 80 TAUs and 32 ROPs.Compare that to the Radeon HD 5830, which uses a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this model. It features 1120(224x5) SPUs along with 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 280 is 11% faster than the Radeon HD 5830 overall, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 280 should be a bit (approximately 8%) faster with regards to texture filtering than the Radeon HD 5830. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 280 is a better choice, by a large margin. (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 max amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high 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 amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 reach the maximum fill rate.
