Xeon E3-1505M v6: CPU benchmarks and laptop guide

The Intel Xeon E3-1505M v6 is the Kaby Lake refresh of Intel's 45 W mobile workstation processor, released in 2017, and five catalog models are matched to it. Against the 69 games the catalog tracks, it meets the recommended CPU requirement in 35 of them. This guide covers where the chip ranks among laptop CPUs, what it offers over its predecessor, and which used Precision workstations carry it.

Where the Xeon E3-1505M v6 sits in 2026

A catalog score of 51.5 places the chip 249th of 741 scored laptop CPUs — a few places above the exact middle of the table. The neighborhood mixes eras: the Core i5-8279U (52.2), Core Ultra 5 225U (52.1) and Core Ultra 5 235U (51.9) just above, with the Ryzen 3 7320U (51.5), Core i7-7920HQ (51.5) and Ryzen 5 PRO 1500 (51.4) just below. Sitting level with 2023–2024 entry-level parts is a reasonable result for a 2017 quad-core, and the sibling Core i7-7920HQ nearby confirms this was the top of its class at launch.

What the chip brings

Kaby Lake-H keeps the 4-core, 8-thread layout of the v5 on the same 14 nm process at 45 W, but raises clocks: 3.0 GHz base and up to 4.0 GHz on boost. ECC memory support carries over — the defining workstation feature of the E3 line. Public benchmarks record a single-core score of 1,243 and a multi-core score of 3,585, a modest step in single-thread speed over the previous generation with multi-core throughput essentially unchanged.

Games: CPU-side readiness

Measured purely as a processor, the chip clears the recommended CPU tier for 35 of 69 cataloged games, including Far Cry 5, F1 24, Diablo 4, Flight Simulator 2020, Doom Eternal, Death Stranding and Watch Dogs Legion. Thirty-two titles sit at the minimum tier — Cyberpunk 2077, Baldur's Gate 3, Elden Ring, Fortnite, Counter-Strike 2 and Alan Wake 2 among them — and only Starfield and Helldivers 2 fall below minimum. These verdicts are CPU-only: whether a game actually plays well depends on the laptop's GPU and RAM, and professional graphics of this generation are hit-or-miss for gaming.

Laptops that carry it

The era-correct machines in the roster are Dell's Precision 5520 at $321, Precision 7520 at $288 and Precision 7720 at $390 — the thin 15-inch workstation and the two big 17-inch chassis of the 2016–2017 generation this chip belongs to. The laptops around it typically show a median office comfort of 75, a performance index of about 45, portability of about 46 and energy efficiency of about 55 — sturdy professional machines that favor memory capacity and build over mobility.

Bottom line

The Xeon E3-1505M v6 is a mid-table workstation processor in 2026: honest quad-core throughput, ECC support, and host machines in the $290–$390 range in this catalog. It suits the same buyer as its v5 predecessor — someone who wants a cheap, well-built used Precision for engineering or office work rather than gaming. With 35 of 69 games at the recommended CPU tier and professional GPUs that show their age, treat any gaming as incidental; the value argument here is workstation build quality at used-laptop pricing.
