Microsoft has revised its Surface buying guide, now recommending 8GB of RAM for everyday tasks, while stating that 16GB or more is necessary for fully utilizing Copilot+ PC features. Previously, Microsoft had advocated for 16GB as the minimum for a satisfactory Windows 11 experience. Earlier this year, Microsoft suggested 32GB of RAM for serious gamers but retracted this recommendation due to backlash over costs. The introduction of Apple's MacBook Neo with 8GB of RAM at an attractive price has influenced Microsoft's stance, leading to the launch of Surface devices with 8GB of RAM. The buying guide promotes 8GB for everyday tasks, while an AI store assistant suggests 16GB for a "future-proof" laptop. Historically, Windows 10 had a minimum RAM requirement of 2GB, with 4GB recommended for optimal performance, but Windows 11 has increased these requirements. Microsoft's investments in AI infrastructure have contributed to a RAM shortage. The Copilot+ PC branding aimed for a new hardware tier but has not met expectations. The introduction of the MacBook Neo has prompted reactions from PC manufacturers, and concerns exist about the optimization of Windows 11 on ARM architecture.
