Our Verdict on Each

A dependable 14nm processor that delivered solid value in 2019 laptops, though it lacks the graphical prowess of Intel's 10nm counterparts.

Best for: Purchasing a heavily discounted used laptop for basic office work.

Read the full review

A highly efficient 9W processor that brought quad-core performance to fanless devices, though its performance is heavily throttled by thermal limits.

Best for: When considering a device with the Core i7-10510Y, it is crucial to understand its intended use case. This processor is best suited for users who prioritize extreme portability, fanless operation, and long battery life, such as students or traveling professionals. It handles web browsing, document editing, and media consumption perfectly fine. However, its 9W TDP means it will quickly throttle under sustained loads like video editing or heavy compiling. In the current market, devices with this CPU should only be purchased used or at a significant discount. Avoid this processor if you plan to do any gaming or intensive rendering. If battery life is your main goal, an Apple Silicon MacBook Air might be a better alternative, but for Windows-based ultra-portables, the 10510Y still offers a competent, albeit aging, experience.
