Compare any two graphics cards:
GeForce GT 320 vs Radeon HD 3850 512MB
IntroThe GeForce GT 320 comes with a clock frequency of 540 MHz and a GDDR3 memory frequency of 790 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It features 72 SPUs, 24 TAUs, and 8 ROPs.Compare those specs to the Radeon HD 3850 512MB, which comes with a GPU core clock speed of 668 MHz, and 512 MB of GDDR3 RAM running at 828 MHz through a 256-bit bus. It also features 320(64x5) SPUs, 16 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 3850 512MB should be a lot faster than the GeForce GT 320 in general. (explain)
Texel RateThe GeForce GT 320 should be a lot (about 21%) more effective at anisotropic filtering than the Radeon HD 3850 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 3850 512MB is a better choice, by far. (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 (counted in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant 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.
