Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs Radeon HD 3850 256MB
IntroThe GeForce GT 240 GDDR5 1GB uses a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 RAM is set to run at a speed of 850 MHz on this specific card. It features 96 SPUs as well as 32 TAUs and 8 ROPs.Compare those specifications to the Radeon HD 3850 256MB, which has a core clock frequency of 668 MHz and a GDDR3 memory speed of 828 MHz. It also makes use of a 256-bit memory bus, and uses a 55 nm design. It is comprised of 320(64x5) SPUs, 16 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 240 GDDR5 1GB should theoretically be a little bit faster than the Radeon HD 3850 256MB overall. (explain)
Texel RateThe GeForce GT 240 GDDR5 1GB will be a lot (approximately 65%) better at texture filtering than the Radeon HD 3850 256MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 3850 256MB is a better choice, and very much so. (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 largest amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can 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 Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
