Compare any two graphics cards:
GeForce 920M vs GeForce GT 130
IntroThe GeForce 920M has a GPU clock speed of 954 MHz, and the 2048 MB of DDR3 memory runs at 900 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 32 Texture Address Units, and 8 ROPs.Compare those specs to the GeForce GT 130, which features GPU clock speed of 500 MHz, and 768 MB of DDR2 RAM running at 250 MHz through a 192-bit bus. It also is comprised of 48 SPUs, 24 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce 920M should theoretically be a small bit faster than the GeForce GT 130 in general. (explain)
Texel RateThe GeForce 920M should be a lot (about 154%) more effective at AF than the GeForce GT 130. (explain)
Pixel RateThe GeForce GT 130 will be just a bit (about 5%) more effective at FSAA than the GeForce 920M, and will be able to handle higher screen resolutions without losing too much performance. (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 max amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its 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 speed of the card. 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 many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
