Our Verdict on Each
An 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.
Read the full reviewA competent mainstream mobile chip that improves on the previous generation with Raptor Cove P-cores. The 2P+4E configuration provides adequate multitasking for everyday use, though heavy workloads will still expose its limitations.
Best for: Mainstream laptop purchase in the $400-$700 range for everyday computing, school, or office work where battery life and adequate performance are both important.
