Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 3850 1GB
IntroThe GeForce GTS 450 1GB has a GPU clock speed of 783 MHz, and the 1024 MB of GDDR5 RAM is set to run at 902 MHz through a 128-bit bus. It also is made up of 192 SPUs, 32 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 3850 1GB, which features a GPU core clock speed of 668 MHz, and 1024 MB of GDDR3 memory running at 828 MHz through a 256-bit bus. It also is comprised of 320(64x5) SPUs, 16 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTS 450 1GB should be 9% quicker than the Radeon HD 3850 1GB overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTS 450 1GB will be quite a bit (more or less 134%) better at texture filtering than the Radeon HD 3850 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTS 450 1GB is superior to the Radeon HD 3850 1GB, not by a very large margin though. (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 (counted in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total 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 a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
