Compare any two graphics cards:
GeForce 8600 GS (OEM) vs GeForce 920M
IntroThe GeForce 8600 GS (OEM) comes with a GPU core speed of 540 MHz, and the 256 MB of DDR2 RAM is set to run at 400 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare all of that to the GeForce 920M, which has a core clock speed of 954 MHz and a DDR3 memory frequency of 900 MHz. It also uses a 64-bit memory bus, and uses a 28 nm design. It features 384 SPUs, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce 920M is 13% quicker than the GeForce 8600 GS (OEM) overall, because of its greater data rate. (explain)
Texel RateThe GeForce 920M is much (approximately 253%) more effective at texture filtering than the GeForce 8600 GS (OEM). (explain)
Pixel RateThe GeForce 920M is much (more or less 77%) faster with regards to full screen anti-aliasing than the GeForce 8600 GS (OEM), and capable of handling higher screen resolutions while still performing well. (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 information (measured in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 are processed in one second. This number is calculated by multiplying the total amount 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 in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
