Compare any two graphics cards:
GeForce GTX 260 216SP 55 nm vs GeForce GTX 980M
IntroThe GeForce GTX 260 216SP 55 nm features core clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 RAM. It features 216 SPUs as well as 72 TAUs and 28 ROPs.Compare those specs to the GeForce GTX 980M, which features a GPU core clock speed of 1038 MHz, and 4096 MB of GDDR5 memory set to run at 1000 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 96 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 980M should theoretically be a bit better than the GeForce GTX 260 216SP 55 nm in general. (explain)
Texel RateThe GeForce GTX 980M will be much (about 140%) better at AF than the GeForce GTX 260 216SP 55 nm. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 980M is superior to the GeForce GTX 260 216SP 55 nm, 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 largest amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
