Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs Radeon HD 3470 512MB
IntroThe GeForce 9500 GT 1GB GDDR3 uses a 55 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR3 memory works at a speed of 800 MHz on this specific model. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare all that to the Radeon HD 3470 512MB, which comes with a core clock speed of 800 MHz and a GDDR3 memory speed of 950 MHz. It also features a 128-bit bus, and uses a 55 nm design. It is comprised of 40(8x5) SPUs, 4 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 3470 512MB should theoretically be a bit better than the GeForce 9500 GT 1GB GDDR3 overall. (explain)
Texel RateThe GeForce 9500 GT 1GB GDDR3 is a lot (about 175%) better at texture filtering than the Radeon HD 3470 512MB. (explain)
Pixel RateThe GeForce 9500 GT 1GB GDDR3 will be a lot (more or less 38%) more effective at full screen anti-aliasing than the Radeon HD 3470 512MB, and will be capable of handling higher resolutions without losing too much performance. (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 maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 maximum number of pixels that the graphics chip 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 colour ROPs by the clock 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 rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
