Compare any two graphics cards:
GeForce GTX 660 vs GeForce GTX 980M
IntroThe GeForce GTX 660 comes with a clock speed of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 192-bit bus, and uses a 28 nm design. It is comprised of 960 SPUs, 80 TAUs, and 24 Raster Operation Units.Compare those specifications to the GeForce GTX 980M, which comes with core speeds of 1038 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 RAM. It features 1536 SPUs along with 96 TAUs and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 660 should perform a small bit faster than the GeForce GTX 980M overall. (explain)
Texel RateThe GeForce GTX 980M is a lot (approximately 27%) more effective at AF than the GeForce GTX 660. (explain)
Pixel RateThe GeForce GTX 980M should be quite a bit (approximately 182%) faster with regards to anti-aliasing than the GeForce GTX 660, and also should be able to handle higher resolutions without losing too much performance. (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 data (measured in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out 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 video card will be at 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 video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
