Compare any two graphics cards:
GeForce GT 430 1GB vs Radeon HD 3470 512MB
IntroThe GeForce GT 430 1GB uses a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this particular card. It features 96 SPUs along with 16 Texture Address Units and 4 Rasterization Operator Units.Compare those specs to the Radeon HD 3470 512MB, which has clock speeds of 800 MHz on the GPU, and 950 MHz on the 512 MB of GDDR3 memory. It features 40(8x5) SPUs along with 4 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon HD 3470 512MB should be 6% quicker than the GeForce GT 430 1GB overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GT 430 1GB should be a lot (approximately 250%) better at texture filtering than the Radeon HD 3470 512MB. (explain)
Pixel RateThe Radeon HD 3470 512MB will be a bit (more or less 14%) better at anti-aliasing than the GeForce GT 430 1GB, and able to handle 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 largest amount of data (counted in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If 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 high 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 the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
