Compare any two graphics cards:
GeForce GTX 480 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 480 features a GPU core speed of 700 MHz, and the 1536 MB of GDDR5 memory runs at 924 MHz through a 384-bit bus. It also is comprised of 480 SPUs, 60 Texture Address Units, and 48 ROPs.Compare those specs to the Radeon HD 6450 (OEM) 1GB, which comes with a core clock frequency of 750 MHz and a GDDR5 memory frequency of 900 MHz. It also makes use of a 64-bit bus, and uses a 40 nm design. It features 160 SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 480 should theoretically perform a lot faster than the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GTX 480 will be a lot (approximately 600%) faster with regards to 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 GTX 480 is a better choice, by far. (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 (measured in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
