Compare any two graphics cards:
GeForce 840M vs GeForce 930M
IntroThe GeForce 840M has a core clock frequency of 1029 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It features 384 SPUs, 24 Texture Address Units, and 8 ROPs.Compare all of that to the GeForce 930M, which has a core clock frequency of 928 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce 840M, in theory, should perform a little bit faster than the GeForce 930M overall. (explain)
Texel RateThe GeForce 840M should be just a bit (about 11%) more effective at AF than the GeForce 930M. (explain)
Pixel RateThe GeForce 840M will be a bit (approximately 11%) faster with regards to anti-aliasing than the GeForce 930M, and also will be capable of handling higher 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 data (measured in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the 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 the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated 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 is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
