Compare any two graphics cards:
GeForce GTX 965M vs Radeon HD 3850 X2
IntroThe GeForce GTX 965M comes with a GPU core clock speed of 944 MHz, and the 2048 MB of GDDR5 memory runs at 1000 MHz through a 128-bit bus. It also features 1024 Stream Processors, 64 Texture Address Units, and 32 Raster Operation Units.Compare all of that to the Radeon HD 3850 X2, which uses a 55 nm design. AMD has set the core speed at 668 MHz. The GDDR3 memory works at a speed of 828 MHz on this particular model. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 3850 X2 should theoretically be quite a bit superior to the GeForce GTX 965M in general. (explain)
Texel RateThe GeForce GTX 965M should be quite a bit (approximately 183%) faster with regards to texture filtering than the Radeon HD 3850 X2. (explain)
Pixel RateThe GeForce GTX 965M is a lot (about 41%) better at full screen anti-aliasing than the Radeon HD 3850 X2, and also will be capable of handling higher screen resolutions without losing too much performance. (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 largest amount of data (measured in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
