Our Verdict on Each

Core i7-5550USituational

A unique Broadwell-U chip that prioritized integrated graphics performance, making it suitable for light creative work in thin laptops.

Best for: Buying a used premium ultrabook for basic media consumption.

Read the full review

A historically significant processor for battery life, but its dual-core architecture is too weak for modern demanding workloads.

Best for: Today, the Core i5-5350U is strictly an end-of-life component and should not be considered for new builds. If you are purchasing a used laptop featuring this processor, it should only be for basic tasks such as web browsing, word processing, and media consumption. It can be found at very low prices on the secondary market, making it a viable option for students or budget-conscious users needing a simple machine. However, its dual-core architecture struggles significantly with modern multitasking and heavy workloads. Ensure the device is priced appropriately for its age, as it lacks support for modern standards like DDR4 memory and PCIe 3.0. Avoid this chip if you intend to do any gaming, video editing, or intensive productivity work.
