Core i7-8565U: CPU benchmarks and laptop guide

The Intel Core i7-8565U was the premium thin-and-light processor of the 2018–2019 laptop generation, and 24 matched models in the catalog still carry it. Judged purely as a processor, it meets the recommended CPU requirement in only 5 of the 69 games the catalog tracks — a number that tells you where eight-year-old ultrabook silicon stands today. This guide covers where the chip ranks, what it brings, and which laptops you will find it in.

Where the Core i7-8565U sits in 2026

A catalog score of 38.13 places the chip 334th of 741 scored laptop CPUs — below the midpoint of the table. The neighborhood is revealing: the Core i3-6098P, Core i5-6267U and Core i7-6660U (all 38.4) sit just above, while the Athlon Gold 7220U (38.1), Ryzen 5 3500U (37.9) and Core i7-1065G7 (37.9) sit just below. In other words, a 2018 flagship U-series i7 now performs on par with 6th-generation desktop-adjacent parts — and its own contemporary rivals — which is a fair picture of how a 15 W quad-core ages.

What the chip brings

Whiskey Lake-U is a 4-core, 8-thread design on a 14 nm process, rated at just 15 W in its U-series configuration. The base clock of 1.8 GHz boosts to 4.6 GHz on a single core — a high ceiling for the era that favored short bursts over sustained load — and integrated graphics are handled by the Intel UHD Graphics 620. Public benchmarks confirm the positioning: a GeekBench single-core score of 804, a multi-core score of 2,327, and a PassMark overall score of 5,954.

Games: CPU-side readiness

Measured as a processor only, the chip clears the recommended CPU tier for 5 of 69 cataloged games: Rise of the Tomb Raider, Mafia Definitive Edition, Rainbow Six Siege, Batman: Arkham Knight and Civilization 6. A large middle band of 41 titles — from Cyberpunk 2077, The Witcher 3, Red Dead Redemption 2 and Doom Eternal to lighter fare like Minecraft, Valorant, Dota 2, League of Legends and Sims 4 — lists the chip above their minimum but below their recommended CPU requirement. The remaining 23, including Starfield, Elden Ring, Fortnite, Counter-Strike 2 and Call of Duty: Warzone, ask for more processor than this. These verdicts are CPU-only: actual playability depends on the laptop's GPU and RAM, and 8565U machines almost universally rely on the modest UHD 620 integrated graphics.

Laptops that carry it

The 24-model roster is a snapshot of the 2018–2020 corporate laptop market, dominated by business machines. Lenovo's ThinkPad T490, T490s, X390, L390 and L490 cluster in the $219–288 range, HP's EliteBook 840 G6 sits at $225, and the IdeaPad S145-15IWL is the budget floor at $177. Two convertibles — the ThinkPad X1 Yoga 4th gen at $333 and HP's Elite x2 G4 at $260 — plus the Precision 3540 at $309 and the ZBook 14u G6 at $282 round out the list, with the HP 250 G7 at $604 as the roster's price ceiling. The laptops built around it typically show a median office comfort score of 75, energy efficiency of 70.7 and portability of 65.6 — alongside a median gaming index of just 23, reflecting the integrated-only graphics of this fleet.

Bottom line

The Core i7-8565U is a processor for the bargain hunter: inside a $177–300 used ThinkPad or EliteBook it still delivers a perfectly usable office, browsing and video machine with good efficiency and light weight. It is not a gaming or heavy-workload option — 64 of 69 cataloged games exceed its recommended CPU tier, and the laptops around it carry no meaningful discrete graphics. For study, remote work or a cheap travel companion it remains serviceable; for anything demanding, the money is better spent one or two generations later.
