Chief Analyst Verdict

Limited Entry-Level Capacity

Validated by C.R. Vinoth Kumar ยท Founder & Senior Editor

8GB of total memory is extremely marginal in 2026. Windows 11 uses 3-4GB at idle, leaving very little headroom for multitasking or gaming. We highly recommend upgrading to at least 16GB, or 32GB to prevent page-file stutters.
