Compare any two graphics cards:
GeForce 9800 GT 512MB vs Radeon HD 3850 256MB
IntroThe GeForce 9800 GT 512MB makes use of a 65/55 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this specific model. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.Compare that to the Radeon HD 3850 256MB, which features GPU core speed of 668 MHz, and 256 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 BandwidthAs far as performance goes, the GeForce 9800 GT 512MB should theoretically be a small bit superior to the Radeon HD 3850 256MB in general. (explain)
Texel RateThe GeForce 9800 GT 512MB should be a lot (more or less 214%) faster with regards to texture filtering than the Radeon HD 3850 256MB. (explain)
Pixel RateThe Radeon HD 3850 256MB should be a little bit (approximately 11%) better at full screen anti-aliasing than the GeForce 9800 GT 512MB, and also should be able to handle higher screen resolutions more effectively. (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 data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
