Compare any two graphics cards:
GeForce GTX 860M vs GeForce GTX 965M
IntroThe GeForce GTX 860M has a GPU core speed of 797 MHz, and the 4096 MB of GDDR5 RAM is set to run at 1000 MHz through a 128-bit bus. It also features 1152 SPUs, 96 Texture Address Units, and 16 ROPs.Compare those specifications to the GeForce GTX 965M, which uses a 28 nm design. nVidia has clocked the core speed at 944 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular card. It features 1024 SPUs along with 64 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same bandwidth, so theoretically they should perform the same. (explain)
Texel RateThe GeForce GTX 860M should be quite a bit (approximately 27%) more effective at AF than the GeForce GTX 965M. (explain)
Pixel RateThe GeForce GTX 965M will be much (approximately 137%) more effective at full screen anti-aliasing than the GeForce GTX 860M, and should be able to handle higher resolutions without slowing down too much. (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 moved past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen 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 amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
