Our Verdict on Each
A niche ultra-low-power variant of the i3-1215U that trades performance for extreme efficiency. Its 9W TDP and 29W PL2 make it suitable for fanless designs, but sustained performance is significantly limited.
Best for: Only if you specifically need a fanless or ultra-quiet laptop for basic tasks and find one at a significant discount compared to a 1215U-based model.
Read the full reviewAn entry-level mobile chip that prioritizes power efficiency over performance. The unusual 1P+4E configuration makes it adequate for basic tasks but limits its capability for anything beyond everyday computing.
Best for: Only if found in a very inexpensive laptop for strictly basic use cases like web browsing and document editing.
