Compare any two graphics cards:
GeForce GTX 965M vs Radeon HD 3850 X2
IntroThe GeForce GTX 965M makes use of a 28 nm design. nVidia has set the core frequency at 944 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this particular card. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.Compare those specs to the Radeon HD 3850 X2, which has core clock speeds of 668 MHz on the GPU, and 828 MHz on the 512 MB of GDDR3 RAM. It features 320(64x5) SPUs as well as 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon HD 3850 X2 should in theory be much superior to the GeForce GTX 965M overall. (explain)
Texel RateThe GeForce GTX 965M will be a lot (approximately 183%) faster with regards to texture filtering than the Radeon HD 3850 X2. (explain)
Pixel RateThe GeForce GTX 965M should be a lot (approximately 41%) better at full screen anti-aliasing than the Radeon HD 3850 X2, and also able to handle higher screen resolutions more effectively. (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

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If 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 high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
