Compare any two graphics cards:
GeForce 830M vs GeForce GTX 275
IntroThe GeForce 830M features core clock speeds of 1029 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 256 SPUs along with 16 Texture Address Units and 8 ROPs.Compare those specs to the GeForce GTX 275, which comes with GPU core speed of 633 MHz, and 896 MB of GDDR3 memory set to run at 1134 MHz through a 448-bit bus. It also is comprised of 240 Stream Processors, 80 Texture Address Units, and 28 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 275 is 782% quicker than the GeForce 830M in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 275 should be a lot (approximately 208%) faster with regards to anisotropic filtering than the GeForce 830M. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 275 is the winner, and very much so. (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 largest amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, 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, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many 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.
