Compare any two graphics cards:
GeForce 940M vs Radeon HD 4550 256MB
IntroThe GeForce 940M has core clock speeds of 1072 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.Compare all of that to the Radeon HD 4550 256MB, which makes use of a 55 nm design. AMD has set the core frequency at 600 MHz. The DDR3 RAM works at a frequency of 800 MHz on this particular model. It features 80(16x5) SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the GeForce 940M should theoretically be a lot superior to the Radeon HD 4550 256MB overall. (explain)
Texel RateThe GeForce 940M should be much (more or less 436%) more effective at anisotropic filtering than the Radeon HD 4550 256MB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 940M is superior to the Radeon HD 4550 256MB, by far. (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 largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics 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 maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
