Microsoft has not clarified the reasoning behind the “Plus” designation for its Copilot+ PCs, which are described as AI-enhanced devices with notable upgrades in hardware and performance. These PCs can reach speeds up to 5x faster than a 5-year-old Windows device and outperform a MacBook Air with the M4 chip. Microsoft claims that Copilot+ PCs enhance “everything Windows 11 does best” and are “up to five times quicker than a 5-year-old Windows 10 device.” The company conducted benchmarks between June and September 2025, claiming that Copilot+ PCs outperform an “average” 5-year-old Windows PC by up to 5x in Cinebench 2024 multi-core performance, although the results have not been made public. Copilot+ machines exhibit up to 3.7x faster AI performance compared to previous-generation Windows 11 AI PCs, with a maximum of 40 TOPs of NPU compared to earlier models' 15 TOPs. Battery life is also improved, offering up to 19 hours of web browsing, 27 hours of local video playback, and 22 hours of streaming. Microsoft asserts that its top-performing Copilot+ PCs surpass the M4 in Cinebench 2024 multi-core tests. The Copilot key is emphasized for its utility in multitasking and quick responses, benefiting students and professionals alike.
