Compare any two graphics cards:
GeForce GTS 450 1GB vs Radeon HD 3850 512MB
IntroThe GeForce GTS 450 1GB comes with a GPU clock speed of 783 MHz, and the 1024 MB of GDDR5 memory is set to run at 902 MHz through a 128-bit bus. It also features 192 SPUs, 32 TAUs, and 16 ROPs.Compare those specs to the Radeon HD 3850 512MB, which comes with GPU clock speed of 668 MHz, and 512 MB of GDDR3 RAM running at 828 MHz through a 256-bit bus. It also is comprised of 320(64x5) Stream Processors, 16 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTS 450 1GB is 9% faster than the Radeon HD 3850 512MB overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTS 450 1GB is quite a bit (more or less 134%) faster with regards to texture filtering than the Radeon HD 3850 512MB. (explain)
Pixel RateThe GeForce GTS 450 1GB will be a small bit (approximately 17%) better at full screen anti-aliasing than the Radeon HD 3850 512MB, and also should be able to handle higher resolutions better. (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 largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
