Compare any two graphics cards:
GeForce GTX 950M vs Radeon HD 3870 512MB
IntroThe GeForce GTX 950M uses a 28 nm design. nVidia has clocked the core frequency at 914 MHz. The DDR3 RAM is set to run at a speed of 1000 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 ROPs.Compare all of that to the Radeon HD 3870 512MB, which comes with a clock speed of 775 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 256-bit bus, and makes use of a 55 nm design. It is comprised of 320(64x5) SPUs, 16 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 3870 512MB should in theory be quite a bit faster than the GeForce GTX 950M overall. (explain)
Texel RateThe GeForce GTX 950M is quite a bit (approximately 195%) faster with regards to AF than the Radeon HD 3870 512MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 950M is the winner, but not by far. (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 information (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card 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 per second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few 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.
