Compare any two graphics cards:
GeForce 930M vs GeForce GTX 280
IntroThe GeForce 930M comes with core speeds of 928 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.Compare that to the GeForce GTX 280, which features GPU core speed of 602 MHz, and 1024 MB of GDDR3 memory running at 1107 MHz through a 512-bit bus. It also is made up of 240 Stream Processors, 80 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce GTX 280, in theory, should perform a lot faster than the GeForce 930M in general. (explain)
Texel RateThe GeForce GTX 280 should be a lot (more or less 116%) faster with regards to AF than the GeForce 930M. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 280 is superior to the GeForce 930M, by a large margin. (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 maximum amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
