Compare any two graphics cards:
GeForce GTX 295 vs GeForce GTX 870M
IntroThe GeForce GTX 295 has a clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also uses a 448-bit memory bus, and uses a 55 nm design. It is comprised of 240 SPUs, 80 TAUs, and 28 ROPs.Compare those specs to the GeForce GTX 870M, which makes use of a 28 nm design. nVidia has set the core frequency at 941 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this particular model. It features 1344 SPUs along with 112 Texture Address Units and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 295 should in theory be much better than the GeForce GTX 870M in general. (explain)
Texel RateThe GeForce GTX 870M will be a bit (approximately 14%) faster with regards to anisotropic filtering than the GeForce GTX 295. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 295 is superior to the GeForce GTX 870M, by far. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
