Compare any two graphics cards:
GeForce 8600 GS (OEM) vs GeForce 920M
IntroThe GeForce 8600 GS (OEM) features core speeds of 540 MHz on the GPU, and 400 MHz on the 256 MB of DDR2 memory. It features 32 SPUs as well as 16 TAUs and 8 ROPs.Compare all of that to the GeForce 920M, which features GPU core speed of 954 MHz, and 2048 MB of DDR3 RAM set to run at 900 MHz through a 64-bit bus. It also features 384 SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce 920M should in theory be a bit faster than the GeForce 8600 GS (OEM) overall. (explain)
Texel RateThe GeForce 920M should be quite a bit (about 253%) better at anisotropic filtering than the GeForce 8600 GS (OEM). (explain)
Pixel RateThe GeForce 920M should be quite a bit (approximately 77%) faster with regards to full screen anti-aliasing than the GeForce 8600 GS (OEM), and also will be able to handle 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 maximum amount of data (measured in megabytes per second) that can be transported 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. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated 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 processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 maximum fill rate.
