Compare any two graphics cards:
GeForce 9800 GTX vs GeForce GTX 860M
IntroThe GeForce 9800 GTX comes with a clock frequency of 675 MHz and a GDDR3 memory frequency of 1100 MHz. It also uses a 256-bit memory bus, and makes use of a 65 nm design. It features 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare all that to the GeForce GTX 860M, which has GPU clock speed of 797 MHz, and 4096 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is comprised of 1152 SPUs, 96 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 9800 GTX should in theory be a small bit better than the GeForce GTX 860M overall. (explain)
Texel RateThe GeForce GTX 860M is a lot (more or less 77%) more effective at AF than the GeForce 9800 GTX. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 860M is the winner, but only just. (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 (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core 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 applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
