Compare any two graphics cards:
GeForce GTX 950M vs Radeon HD 4650 1GB
IntroThe GeForce GTX 950M comes with a GPU core speed of 914 MHz, and the 2048 MB of DDR3 memory is set to run at 1000 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 ROPs.Compare those specs to the Radeon HD 4650 1GB, which comes with a clock frequency of 600 MHz and a GDDR3 memory speed of 700 MHz. It also makes use of a 128-bit memory bus, and makes use of a 55 nm design. It is made up of 320(64x5) SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthThe GeForce GTX 950M should in theory be quite a bit faster than the Radeon HD 4650 1GB in general. (explain)
Texel RateThe GeForce GTX 950M will be quite a bit (approximately 90%) faster with regards to texture filtering than the Radeon HD 4650 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 950M is superior to the Radeon HD 4650 1GB, 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: Bandwidth is the max amount of data (in units of MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
