Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs Radeon HD 3470 512MB
IntroThe GeForce 9500 GT 512MB GDDR3 features a clock speed of 550 MHz and a GDDR3 memory speed of 800 MHz. It also makes use of a 128-bit bus, and makes use of a 55 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 3470 512MB, which features GPU core speed of 800 MHz, and 512 MB of GDDR3 RAM set to run at 950 MHz through a 128-bit bus. It also features 40(8x5) Stream Processors, 4 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 3470 512MB should in theory be a small bit superior to the GeForce 9500 GT 512MB GDDR3 in general. (explain)
Texel RateThe GeForce 9500 GT 512MB GDDR3 is quite a bit (more or less 175%) faster with regards to AF than the Radeon HD 3470 512MB. (explain)
Pixel RateThe GeForce 9500 GT 512MB GDDR3 will be a lot (more or less 38%) better at AA than the Radeon HD 3470 512MB, and will be able to handle higher resolutions better. (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 largest amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
