CPU Comparison

Core i5-7300HQ vs Intel Core i7-8550U

A side-by-side comparison of specs, performance and value. The Intel Core i5-7300HQ is a 7th generation mobile processor that became a staple in budget gaming laptops upon its release in early 2017. Built on the Kaby Lake-H architecture, this 14nm chip features 4 cores and 4 threads, operating at a 2.5 GHz base clock with a maximum turbo boost of 3.5 GHz. Its 45W TDP allowed it to sustain higher performance over long periods compared to thinner, lower-wattage laptops. The 7300HQ includes Intel HD Graphics 630, though laptops featuring this CPU almost always included a dedicated GPU for actual gaming workloads. It supports dual-channel DDR4 memory, ensuring sufficient bandwidth for mid-range components. As a BGA1440 chip, it is soldered directly to the motherboard, limiting upgradeability. During its peak, the 7300HQ powered millions of affordable gaming machines, offering a reliable entry point into PC gaming for users who couldn't afford premium Core i7 configurations.

Our Verdict on Each

Core i5-7300HQSituational

A highly popular mobile CPU that brought affordable quad-core performance to gaming laptops, though its 4-core/4-thread design is heavily outdated for modern workloads.

Best for: Buying a very cheap used laptop for basic retro gaming

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.
