CPU Comparison
Intel Core i5-8350U vs Intel Core i7-8650U
A side-by-side comparison of specs, performance and value. The Intel Core i5-8350U is a quad-core mobile processor from Intel's 8th Generation Kaby Lake-R lineup, engineered for thin-and-light ultrabooks and business laptops. Operating at a base frequency of 1.7 GHz and dynamically boosting up to 3.6 GHz, it utilizes Intel's highly optimized 14nm manufacturing process. The transition from dual-core to quad-core configurations in the U-series was a major leap for mobile productivity, bringing 8 threads to low-power devices. With 6MB of L3 Smart Cache, it ensures efficient task management for everyday office work, heavy web browsing, and moderate multitasking. It integrates Intel UHD Graphics 620, which is sufficient for hardware-accelerated video playback and basic display duties, though not intended for 3D gaming. Maintaining a strict 15W TDP, the i5-8350U balances sustained performance with battery longevity, making it a popular choice for professionals requiring reliable computing power in a portable form factor.

Our Verdict on Each
A solid quad-core low-power processor that brought significant multi-threaded gains to ultrabooks, though its integrated graphics remain a limiting factor.
Best for: Purchasing a heavily discounted used business laptop for basic office work.
Read the full reviewThe Core i7-8650U is a 15W mobile CPU with vPro support, designed for business ultrabooks.
Best for: The Intel Core i7-8650U is a processor you will encounter primarily in the refurbished business laptop market. It is an excellent choice for professionals or students who need a reliable, portable machine for office work, web browsing, and video conferencing. The inclusion of vPro technology makes it particularly appealing for IT departments or users who require remote management capabilities. However, like other 15W 8th Gen chips, its low base clock means it will throttle under heavy sustained workloads. Avoid purchasing a laptop with this CPU if you need to do video editing, 3D rendering, or gaming. It is best suited for budget-conscious buyers looking for a high-quality, durable business ultrabook like a used ThinkPad X1 Carbon or Dell Latitude.
