Compare any two graphics cards:
GeForce GTX 285 1GB vs Radeon HD 6450 (OEM)
IntroThe GeForce GTX 285 1GB has a GPU core speed of 648 MHz, and the 1024 MB of GDDR3 RAM runs at 1242 MHz through a 512-bit bus. It also is comprised of 240 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.Compare those specs to the Radeon HD 6450 (OEM), which comes with GPU clock speed of 625 MHz, and 512 MB of GDDR3 RAM set to run at 800 MHz through a 64-bit bus. It also features 160 SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 285 1GB is 1142% quicker than the Radeon HD 6450 (OEM) overall, because of its higher data rate. (explain)
Texel RateThe GeForce GTX 285 1GB is much (more or less 937%) better at AF than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe GeForce GTX 285 1GB should be much (about 729%) more effective at full screen anti-aliasing than the Radeon HD 6450 (OEM), and should be able to handle higher 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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core clock 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 number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
