Compare any two graphics cards:
GeForce GTX 285 2GB vs Radeon HD 6850
IntroThe GeForce GTX 285 2GB uses a 55 nm design. nVidia has clocked the core speed at 648 MHz. The GDDR3 RAM runs at a frequency of 1242 MHz on this particular card. It features 240 SPUs along with 80 Texture Address Units and 32 ROPs.Compare those specs to the Radeon HD 6850, which uses a 40 nm design. AMD has clocked the core frequency at 775 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this specific model. It features 960 SPUs along with 48 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 285 2GB should theoretically be quite a bit faster than the Radeon HD 6850 overall. (explain)
Texel RateThe GeForce GTX 285 2GB is a lot (approximately 39%) better at AF than the Radeon HD 6850. (explain)
Pixel RateThe Radeon HD 6850 is just a bit (more or less 20%) better at FSAA than the GeForce GTX 285 2GB, and capable of handling higher resolutions without slowing down too much. (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 (counted in megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at 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 card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
