Compare any two graphics cards:
GeForce GT 320 vs Radeon HD 3850 256MB
IntroThe GeForce GT 320 features core clock speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 memory. It features 72 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.Compare that to the Radeon HD 3850 256MB, which features a clock speed of 668 MHz and a GDDR3 memory frequency of 828 MHz. It also features a 256-bit bus, and makes use of a 55 nm design. It features 320(64x5) SPUs, 16 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 3850 256MB should perform quite a bit faster than the GeForce GT 320 in general. (explain)
Texel RateThe GeForce GT 320 will be quite a bit (more or less 21%) more effective at anisotropic filtering than the Radeon HD 3850 256MB. (explain)
Pixel RateThe Radeon HD 3850 256MB is much (more or less 147%) faster with regards to anti-aliasing than the GeForce GT 320, and will be capable of handling higher resolutions while still performing well. (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 moved past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
