Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 7850
IntroThe GeForce GTS 250 1GB uses a 65/55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 RAM works at a frequency of 1100 MHz on this model. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.Compare those specs to the Radeon HD 7850, which uses a 28 nm design. AMD has clocked the core speed at 860 MHz. The GDDR5 memory works at a frequency of 1200 MHz on this card. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7850 should in theory perform a lot faster than the GeForce GTS 250 1GB in general. (explain)
Texel RateThe Radeon HD 7850 is just a bit (approximately 17%) more effective at anisotropic filtering than the GeForce GTS 250 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 7850 is the winner, and very much so. (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: Bandwidth is the max amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type 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 AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
