Compare any two graphics cards:
GeForce 940M vs Radeon HD 3650 512MB
IntroThe GeForce 940M comes with a core clock frequency of 1072 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit memory bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.Compare that to the Radeon HD 3650 512MB, which features core speeds of 725 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 memory. It features 120(24x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the Radeon HD 3650 512MB should theoretically be much superior to the GeForce 940M in general. (explain)
Texel RateThe GeForce 940M will be much (approximately 344%) faster with regards to anisotropic filtering than the Radeon HD 3650 512MB. (explain)
Pixel RateThe GeForce 940M will be a lot (more or less 196%) faster with regards to FSAA than the Radeon HD 3650 512MB, and also will be capable of handling higher 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
