Our Verdict on Each

A reliable and efficient mobile CPU that brought 4 cores to thin-and-light laptops, still serviceable for basic tasks today.

Best for: Buying a cheap used laptop for basic tasks

Read the full review

A pioneering 15W processor that brought 4 cores to ultrabooks, offering solid multitasking, though its low base clock limits sustained performance.

Best for: If you are considering a laptop with the Core i7-8550U today, it should only be purchased in the used or refurbished market at a significant discount. It remains a capable processor for everyday tasks like web browsing, document editing, and media consumption. The 4-core design ensures it handles basic multitasking without major slowdowns. However, its 14nm architecture and 15W TDP mean it will struggle with any sustained heavy workloads like video editing or modern gaming. Avoid this processor if you need to run demanding software or if battery life is your absolute top priority, as newer chips are far more efficient. It is best suited for budget-conscious buyers or students who need a cheap, reliable secondary machine for schoolwork and everyday use.
