Compare any two graphics cards:
GeForce GTX 285 1GB vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 285 1GB makes use of a 55 nm design. nVidia has set the core frequency at 648 MHz. The GDDR3 RAM works at a speed of 1242 MHz on this model. It features 240 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which makes use of a 40 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 memory is set to run at a frequency of 900 MHz on this particular card. It features 160 SPUs as well as 8 TAUs and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 285 1GB will be 452% faster than the Radeon HD 6450 (OEM) 1GB overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 285 1GB will be much (approximately 764%) faster with regards to AF than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTX 285 1GB is a lot (more or less 591%) faster with regards to full screen anti-aliasing than the Radeon HD 6450 (OEM) 1GB, and able to handle higher screen resolutions without slowing down too much. (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 maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's interface 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 4 instead. The better the bandwidth is, the better 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 figure is worked out by multiplying the total amount of texture units of the card by the core 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 in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
