Compare any two graphics cards:
GeForce GTX 950M vs Radeon HD 4670 1GB
IntroThe GeForce GTX 950M makes use of a 28 nm design. nVidia has set the core speed at 914 MHz. The DDR3 memory works at a speed of 1000 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.Compare all that to the Radeon HD 4670 1GB, which uses a 55 nm design. AMD has clocked the core speed at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 RAM is set to run at a speed of 1100 MHz on this specific model. It features 320(64x5) SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 4670 1GB should theoretically be a small bit superior to the GeForce GTX 950M overall. (explain)
Texel RateThe GeForce GTX 950M should be a lot (more or less 52%) better at AF than the Radeon HD 4670 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 950M is superior to the Radeon HD 4670 1GB, 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 max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
