Compare any two graphics cards:
GeForce GTX 950M vs Radeon HD 3870 1GB
IntroThe GeForce GTX 950M makes use of a 28 nm design. nVidia has set the core frequency at 914 MHz. The DDR3 RAM runs at a frequency of 1000 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 3870 1GB, which makes use of a 55 nm design. AMD has set the core speed at 775 MHz. The GDDR4 RAM runs at a speed of 1125 MHz on this particular model. It features 320(64x5) SPUs along with 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 3870 1GB, in theory, should perform much faster than the GeForce GTX 950M in general. (explain)
Texel RateThe GeForce GTX 950M is quite a bit (about 195%) better at anisotropic filtering than the Radeon HD 3870 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 950M is a better choice, 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 maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
