Compare any two graphics cards:
GeForce 9600 GT 512MB vs Radeon HD 4830 1GB
IntroThe GeForce 9600 GT 512MB makes use of a 65/55 nm design. nVidia has set the core speed at 650 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this particular model. It features 64 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.Compare all that to the Radeon HD 4830 1GB, which comes with a GPU core clock speed of 575 MHz, and 1024 MB of GDDR4 memory running at 900 MHz through a 256-bit bus. It also is comprised of 640(128x5) Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthBoth cards have the exact same bandwidth, so in theory they should perform exactly the same. (explain)
Texel RateThe GeForce 9600 GT 512MB will be just a bit (approximately 13%) better at anisotropic filtering than the Radeon HD 4830 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce 9600 GT 512MB is a better choice, but only just. (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 maximum amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video 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 most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's 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 rate also depends on many 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.
