Compare any two graphics cards:
GeForce GTX 650 vs GeForce GTX 980M
IntroThe GeForce GTX 650 features a clock speed of 1058 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 32 TAUs, and 16 Raster Operation Units.Compare that to the GeForce GTX 980M, which has GPU clock speed of 1038 MHz, and 4096 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also is made up of 1536 Stream Processors, 96 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 980M, in theory, should be quite a bit faster than the GeForce GTX 650 in general. (explain)
Texel RateThe GeForce GTX 980M is quite a bit (about 194%) more effective at AF than the GeForce GTX 650. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 980M is a better choice, 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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core 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 applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
