Compare any two graphics cards:
GeForce 8800 GT 1GB vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce 8800 GT 1GB uses a 65 nm design. nVidia has clocked the core frequency at 600 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this specific card. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.Compare all that to the Radeon HD 6450 (OEM) 1GB, which features clock speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 RAM. It features 160 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 8800 GT 1GB is 100% faster than the Radeon HD 6450 (OEM) 1GB overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce 8800 GT 1GB is quite a bit (approximately 460%) better at texture filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 8800 GT 1GB 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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the video card could 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 Raster Operations Pipelines by the the card's 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
