Core Ultra 7 258V: CPU benchmarks and laptop guide

The Intel Core Ultra 7 258V is the Lunar Lake flagship — the efficiency-first design where Intel put battery life ahead of core count, and 51 catalog models carry it. An 8-core chip on a 3 nm-class process running at just 17 W, it still meets the recommended CPU requirement in 68 of the 69 games the catalog tracks. This guide covers where it sits among laptop CPUs, what it brings, and which laptops carry it.

Where the Core Ultra 7 258V sits in 2026

A catalog score of 83.9 places the chip 32nd of 672 scored laptop CPUs — the top five percent — remarkable for a 17 W part in a table full of 45–55 W gaming silicon. The neighborhood: the Ryzen 7 PRO 7840HS (84.7), Core Ultra 7 268V (84.3) and Core Ultra 7 256V (83.9) just above, the Ryzen 5 7640HS (82.6), Ryzen AI 5 340 (82.5) and Ryzen 7 PRO 7840U (81.6) just below. Ranking alongside 45 W H-class chips at 17 W is the whole story of this silicon: near-mainstream-performance per watt nothing else in the table matches.

What the chip brings

Lunar Lake trades threads for efficiency: 8 cores and 8 threads — no hyper-threading — on a 3 nm-class process at a 17 W P-class rating, 2.2 GHz base and up to 4.8 GHz boost. The Arc Graphics 140V integrated tile runs 300–1,950 MHz and carries the display workload; on-package memory means no upgrade path, so the RAM the laptop ships with is the RAM it keeps. GeekBench places the chip at 2,408 single-core and 9,599 multi-core — single-thread figures that hang with the big flags, multi-thread figures honest about the core count.

Games: CPU-side readiness

As a processor, the chip clears the recommended CPU tier for 68 of 69 cataloged games — Cyberpunk 2077, Elden Ring, Hogwarts Legacy, Fortnite and the whole competitive field included. The lone exception is Starfield, which lists the chip above its minimum but under its recommended CPU requirement. These verdicts measure the processor only: the 258V fleet is thin-and-light territory with integrated graphics, so demanding titles remain GPU-bound regardless of how comfortably the CPU side clears.

Laptops that carry it

The 51-model roster is uniformly premium and portable: Samsung Galaxy Book 5 Pro in 14 and 16 inch, MSI Prestige 13 AI+, LG Gram 16, Lenovo Yoga Slim 9i and the Acer Swift Edge and Swift Go lines cluster at $1,232; the Vivobook 14/16 Flip convertibles and Yoga Slim 9i at $1,275; Acer's Aspire 16 AI is the value entry at $765. Roster medians describe the design intent: mobility 86.5 and energy efficiency 92.5 — both top-of-class — with office comfort at a perfect 100, while gaming index 19 and a zero best-GPU median confirm this is not a gaming fleet.

Bottom line

The Core Ultra 7 258V is the pick when the laptop is an all-day tool rather than a gaming rig: top-five-percent processor rank from a 17 W envelope, recommended-tier CPU clearance for everything but Starfield, and a roster of genuinely light machines — Grams, Yoga Slims, Galaxy Books — clustered around $1,232. The trade-offs are honest: no discrete-GPU fleet, no RAM upgrades, and multi-thread throughput behind the H-class chips around it. Compare pages against the 255H and the 256V price the performance-for-portability trade precisely.
