Compare any two graphics cards:
GeForce GTX 980M vs Radeon HD 3470 256MB
IntroThe GeForce GTX 980M features a core clock frequency of 1038 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It features 1536 SPUs, 96 Texture Address Units, and 64 Raster Operation Units.Compare those specs to the Radeon HD 3470 256MB, which makes use of a 55 nm design. AMD has set the core frequency at 800 MHz. The DDR2 RAM works at a frequency of 950 MHz on this particular card. It features 40(8x5) SPUs as well as 4 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce GTX 980M should be quite a bit faster than the Radeon HD 3470 256MB overall. (explain)
Texel RateThe GeForce GTX 980M is much (more or less 3014%) better at texture filtering than the Radeon HD 3470 256MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 980M is a better choice, and very much so. (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 information (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 can be processed in one second. This is calculated by multiplying the total texture units of the card by the core 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 processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
