GeForce GTX 860M vs Iris Graphics 6100

When choosing between GeForce GTX 860M and Iris Graphics 6100, it is worth examining the specifications of the models in detail. Do they meet the recommended requirements of modern games and software? Storage capacity, form factor, TDP, available ports, warranty and manufacturer support are all important. For example, the size of a PC case can limit the maximum thickness and length of the card. Often, instead of the factory overclocked card and RGB backlight, it is better to choose a reference model with a more efficient GPU. And make sure that your current power supply unit has the correct connection pins (using adapters is not recommended). This GPUs compare tool is meant to help you to choose the best graphics card for your build. Let's find out the difference between GeForce GTX 860M and Iris Graphics 6100.
