Compare any two graphics cards:
GeForce GTX 480 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 480 has core speeds of 700 MHz on the GPU, and 924 MHz on the 1536 MB of GDDR5 memory. It features 480 SPUs as well as 60 TAUs and 48 Rasterization Operator Units.Compare those specs to the Radeon HD 6450 (OEM) 1GB, which features a GPU core clock speed of 750 MHz, and 1024 MB of GDDR5 memory set to run at 900 MHz through a 64-bit bus. It also is made up of 160 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 480 is 516% quicker than the Radeon HD 6450 (OEM) 1GB overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 480 is quite a bit (about 600%) more effective at anisotropic filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTX 480 should be quite a bit (about 1020%) better at full screen anti-aliasing than the Radeon HD 6450 (OEM) 1GB, and will be capable of handling higher resolutions while still performing well. (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 data (in units of MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range 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 is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
