Core i7-8550U: CPU benchmarks and laptop guide

The Intel Core i7-8550U was the volume quad-core of Intel's 2017 Kaby Lake Refresh U-series — the chip that brought four cores to mainstream business ultrabooks. The catalog matches it to 16 models, and it meets the recommended CPU requirement in 7 of the 69 games the site tracks. This guide covers where the chip sits among laptop CPUs, what it brings to a portable, and which laptops carry it.

Where the Core i7-8550U sits in 2026

A catalog score of 40.8 places the chip 356th of 737 scored laptop CPUs — the middle of a table that spans two decades of silicon. The neighborhood sits within half a point in either direction: the Ryzen 3 2300U (41.4), Core i5-7267U (41.2) and Core i7-6567U (41) just above, the Pentium 6805 (40.7), Core i5-7260U (40.7) and Core i7-4712HQ (40.5) just below. Trading places with an older-generation i7 quad and a mobile Pentium in the same breath is the honest picture: mainstream silicon in 2017, mainstream silicon now.

What the chip brings

Kaby Lake Refresh is a 4-core, 8-thread design on a 14 nm process, rated at 15 W in its U-class configuration: a 1.8 GHz base clock and up to 4.0 GHz boost, with the integrated UHD Graphics 620 carrying display duty. Memory support and cache details were not captured for this chip, so the table above sticks to what the catalog verifiably holds: 878 single-core and 2,622 multi-core in Geekbench, plus a PassMark overall score of 6,118.

Games: CPU-side readiness

Measured purely as a processor, the chip clears the recommended CPU tier for 7 of 69 cataloged games — Grand Theft Auto V, Overwatch, Batman: Arkham Knight, Rainbow Six Siege, Mafia Definitive Edition, Rise of the Tomb Raider and Civilization 6. Another 42 sit at the minimum tier — Cyberpunk 2077, The Witcher 3: Wild Hunt, Red Dead Redemption 2, Minecraft, Valorant, Dota 2 and League of Legends among them. The remaining 20, from Fortnite and Elden Ring to Baldur's Gate 3, Counter-Strike 2 and Starfield, ask for more processor than this. These verdicts are CPU-only — whether a game actually plays well depends on the laptop's GPU and RAM, and those vary widely across this roster.

Laptops that carry it

The 16-model roster splits in two. The 2017–2018 corporate core — HP EliteBook 840 G5 at $217, ThinkPad T480 at $256, Dell Latitude 5490 at $212, Inspiron 5570 at $269, ProBook 650 G5 at $256 — is joined by convertibles in the ZBook x2 G4 ($385), EliteBook x360 1040 G5 ($328) and ThinkPad X1 YOGA ($357), and by newer listings still built around the 2017 chip: Acer Aspire 5 (A517-58) at $553, the Gaming-class Aspire 5 (A517-52) at $590 and a 2025 Acer TravelMate P2 (TMP215-55) at $1,144. Roster medians describe the fleet, not the chip: office comfort at 50, performance at 34, mobility at 47 and a gaming index of 27.5 — modest numbers for modest machines.

Bottom line

The Core i7-8550U still makes sense at its used-market floor: the 2017-vintage business listings around $212 to $269 buy solid keyboards and dock-friendly machines for office and study work. The higher-priced listings deserve scrutiny — a 2025 machine at $1,144 carrying a 2017 processor is selling build and support, not speed. And for gaming, 7 of 69 recommended-tier titles is the honest ceiling; treat this chip as a work tool, not a play one.
