Compare any two graphics cards:
GeForce 8500 GT vs GeForce GTX 965M
IntroThe GeForce 8500 GT makes use of a 80 nm design. nVidia has clocked the core frequency at 450 MHz. The DDR2 memory runs at a speed of 400 MHz on this specific card. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.Compare all that to the GeForce GTX 965M, which features a GPU core clock speed of 944 MHz, and 2048 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is comprised of 1024 Stream Processors, 64 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 965M should theoretically be a lot superior to the GeForce 8500 GT overall. (explain)
Texel RateThe GeForce GTX 965M should be quite a bit (about 1578%) better at texture filtering than the GeForce 8500 GT. (explain)
Pixel RateThe GeForce GTX 965M should be a lot (more or less 1578%) more effective at FSAA than the GeForce 8500 GT, and 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 maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core 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 in one second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
