Compare any two graphics cards:
GeForce 9800 GT 1GB vs GeForce GTX 860M
IntroThe GeForce 9800 GT 1GB makes use of a 65/55 nm design. nVidia has clocked the core frequency at 600 MHz. The GDDR3 memory works at a frequency of 900 MHz on this card. It features 112 SPUs along with 56 Texture Address Units and 16 ROPs.Compare all of that to the GeForce GTX 860M, which uses a 28 nm design. nVidia has set the core frequency at 797 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this particular card. It features 1152 SPUs as well as 96 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 860M should be just a bit faster than the GeForce 9800 GT 1GB overall. (explain)
Texel RateThe GeForce GTX 860M is quite a bit (approximately 128%) better at texture filtering than the GeForce 9800 GT 1GB. (explain)
Pixel RateThe GeForce GTX 860M is a lot (more or less 33%) faster with regards to full screen anti-aliasing than the GeForce 9800 GT 1GB, and also capable of handling higher screen resolutions without slowing down too much. (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 maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
