Compare any two graphics cards:
GeForce GTX 960M vs Radeon HD 3850 256MB
IntroThe GeForce GTX 960M features a GPU clock speed of 1096 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1000 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.Compare all of that to the Radeon HD 3850 256MB, which uses a 55 nm design. AMD has set the core frequency at 668 MHz. The GDDR3 RAM is set to run at a speed of 828 MHz on this particular model. It features 320(64x5) SPUs along with 16 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 960M should in theory be a lot superior to the Radeon HD 3850 256MB in general. (explain)
Texel RateThe GeForce GTX 960M will be quite a bit (approximately 310%) faster with regards to AF than the Radeon HD 3850 256MB. (explain)
Pixel RateThe GeForce GTX 960M should be a lot (more or less 64%) more effective at FSAA than the Radeon HD 3850 256MB, and should be able to handle higher screen 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: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount 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 processed in a second. Pixel Rate: Pixel rate is the most pixels the video 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 ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
