Our Verdict on Each
A competent entry-level hybrid mobile chip that introduced the P+E architecture to the i3 laptop segment. Adequate for everyday tasks, though the 8-thread ceiling and 15W power limit constrain heavier workloads.
Best for: Purchasing a budget to mid-range laptop in 2022-2023 for everyday tasks, schoolwork, and office use where battery life matters more than raw performance.
Read the full reviewAn impressive technical achievement in power efficiency, packing 8 E-cores into 7W. However, the combination of no P-cores, single-channel memory, and PCIe 3.0 limits it to the simplest computing tasks where power draw matters more than speed.
Best for: Fanless mini PC or Chromebook purchase where silence, minimal power draw, and adequate basic performance are the primary requirements.
