Compare any two graphics cards:
GeForce GTX 950M vs Radeon HD 3470 256MB
IntroThe GeForce GTX 950M has core clock speeds of 914 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.Compare all that to the Radeon HD 3470 256MB, which features a core clock frequency of 800 MHz and a DDR2 memory speed of 950 MHz. It also features a 128-bit memory bus, and makes use of a 55 nm design. It is made up of 40(8x5) SPUs, 4 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce GTX 950M, in theory, should perform a small bit faster than the Radeon HD 3470 256MB overall. (explain)
Texel RateThe GeForce GTX 950M should be a lot (more or less 1043%) faster with regards to AF than the Radeon HD 3470 256MB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 950M is a better choice, by a large margin. (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 data (counted in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of 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 better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
