Compare any two graphics cards:
GeForce GT 450 (OEM) vs Radeon HD 5850
IntroThe GeForce GT 450 (OEM) makes use of a 40 nm design. nVidia has clocked the core speed at 790 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this specific card. It features 144 SPUs along with 24 Texture Address Units and 24 ROPs.Compare that to the Radeon HD 5850, which uses a 40 nm design. AMD has clocked the core speed at 725 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific card. It features 1440(288x5) SPUs as well as 72 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 5850 should theoretically be quite a bit superior to the GeForce GT 450 (OEM) overall. (explain)
Texel RateThe Radeon HD 5850 is a lot (approximately 175%) better at AF than the GeForce GT 450 (OEM). (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 5850 is superior to the GeForce GT 450 (OEM), 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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units 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 one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. 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 bandwidth is, the lower the ability to reach the max fill rate.
