Compare any two graphics cards:
GeForce GT 450 (OEM) vs Radeon HD 5830
IntroThe GeForce GT 450 (OEM) makes use of a 40 nm design. nVidia has clocked the core speed at 790 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this specific card. It features 144 SPUs along with 24 Texture Address Units and 24 Rasterization Operator Units.Compare all that to the Radeon HD 5830, which has core clock speeds of 800 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 1120(224x5) SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5830 should be 33% quicker than the GeForce GT 450 (OEM) overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 5830 will be a lot (about 136%) better at anisotropic filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GT 450 (OEM) is superior to the Radeon HD 5830, 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 (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of 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.
