Intel Core i7-8550U vs Intel Core i7-8705G
A side-by-side comparison of specs, performance and value. The Intel Core i7-8550U is an ultra-low power mobile processor launched in August 2017 as part of the 8th Generation Kaby Lake-U Refresh family. Designed for thin-and-light laptops, it marked a significant milestone by introducing 4 cores and 8 threads to the 15-watt TDP category, a substantial upgrade from the dual-core designs of previous generations. Built on Intel's 14nm process, it operates at a base clock of 1.8 GHz and can boost up to 4.0 GHz. The processor features 8MB of L3 cache, doubling the cache size of its 7th Gen predecessors. It integrates Intel UHD Graphics 620 for basic multimedia tasks and hardware-accelerated video decoding. While its low base clock limits performance under sustained multi-threaded loads, the aggressive turbo boost ensures snappy responsiveness for everyday productivity. The i7-8550U became one of the most popular ultrabook processors of its era, powering countless mainstream laptops and bringing true quad-core performance to the portable form factor.

Our Verdict on Each
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.
