Core i7-8550U Details

The Intel Core i7-8550U, launched in August 2017, remains a capable mobile processor despite its age, offering a compelling balance of performance and efficiency for mainstream laptop use. As of March 2026, it competes in a market dominated by newer architectures, yet it still holds a notable position in the broader CPU landscape. With a base clock of 1.8 GHz and a turbo frequency reaching up to 4.0 GHz, the four-core, eight-thread processor delivers strong single-threaded performance, placing it at #629 in single-core rankings and achieving a score of 5414. This makes it a strong contender against many modern mid-range CPUs, especially in applications that benefit from high clock speeds. However, its multicore performance, while respectable at #896 overall with a score of 4762, is less competitive compared to newer multi-core designs, particularly in workloads that can leverage multiple threads effectively.

Built on Intel’s Kaby Lake Refresh microarchitecture and manufactured on a 14 nm process, the Core i7-8550U features a 15 W TDP, which allows it to run cool and efficiently in thin and light devices. It supports DDR4-2400 and LPDDR3-2133 memory, with a maximum capacity of 32 GB and memory bandwidth up to 35.76 GB/s. The processor includes 8 MB of L3 cache and 1 MB of L2 cache, with 128 KB of L1 cache per core, enhancing data access speed. Its integrated UHD Graphics 620 GPU, featuring 24 execution units and a max frequency of 1.15 GHz, provides adequate performance for light gaming and multimedia tasks, supporting up to three displays.

The Core i7-8550U benefits from a range of modern features, including Intel’s Hyper-Threading, which effectively doubles the thread count, as well as advanced instruction sets such as AVX and AVX2, which accelerate scientific and media processing. It also supports hardware virtualization technologies like Intel VT-x and VT-d, making it suitable for virtualization and development environments. Despite being an older design, it remains relevant in budget and mid-tier laptops, particularly where power efficiency and integrated graphics are prioritized over raw computational power.

In the broader context of CPU performance, the Core i7-8550U ranks #742 overall with a Passmark score of 5153, indicating solid mid-tier performance. While it is outpaced by modern high-end processors, it still holds its own against many desktop and mobile CPUs released in the same era. Its strongest category is single-core performance, where it excels, but it shows limitations in sustained multi-threaded workloads. For users seeking a reliable processor for everyday productivity, web browsing, and light content creation, the Core i7-8550U remains a viable choice, especially in systems where power consumption and thermal constraints are key considerations.
