Compare any two graphics cards:
GeForce 9600 GT 1GB vs Radeon HD 4830 1GB
IntroThe GeForce 9600 GT 1GB has a core clock frequency of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 256-bit memory bus, and uses a 65/55 nm design. It features 64 SPUs, 32 TAUs, and 16 ROPs.Compare those specs to the Radeon HD 4830 1GB, which features clock speeds of 575 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR4 RAM. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthBoth cards have exactly the same bandwidth, so theoretically they should perform the same. (explain)
Texel RateThe GeForce 9600 GT 1GB will be a little bit (more or less 13%) better at texture filtering than the Radeon HD 4830 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 9600 GT 1GB is superior to the Radeon HD 4830 1GB, 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 max amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units 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 a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to 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 bandwidth is, the lower the ability to get to the maximum fill rate.
