Xeon E3-1505M v5: CPU benchmarks and laptop guide

The Intel Xeon E3-1505M v5 is the Skylake-based mobile workstation processor from 2015, the chip that anchored Dell's Precision line of that generation, 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 brings, and which used workstations you will find it in.

Where the Xeon E3-1505M v5 sits in 2026

A catalog score of 50.8 places the chip 261st of 741 scored laptop CPUs — right around the middle of the table. The neighborhood is a generational mix: the Ryzen 5 7520U (51.1), Core i5-8400H (51) and Core i5-8300H (50.9) just above, with the Core i7-1260P (50.8), Core Ultra 7 155U (50.5) and Ryzen 3 4300U (50.4) just below. Ranking level with parts released three to eight years later is a decent showing for 2015 silicon, though those newer chips reach the same place with better efficiency.

What the chip brings

This Xeon is a 4-core, 8-thread Skylake design on a 14 nm process, rated at 45 W: 2.8 GHz base with boosts up to 3.7 GHz, plus ECC memory support — the workstation differentiator of the E3 line. Public benchmarks record a single-core score of 1,168 and a multi-core score of 3,642, figures that describe a capable quad-core of the mid-2010s rather than anything exotic. In practice it behaves like the Core i7-6820HQ of the same generation, with the workstation feature set on top.

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 and Death Stranding. 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: actual playability depends on the laptop's GPU and RAM, and workstation graphics of this era vary in how well they translate to games.

Laptops that carry it

The era-correct machines in the roster are Dell's Precision 5510 from 2015 at $297, plus the Precision 5520 and 7720 from 2016 at $321 and $390 — thin and big-chassis mobile workstations respectively, built in the chip's own platform generation. 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 — professional builds that prioritized build quality and memory capacity over mobility or gaming.

Bottom line

The Xeon E3-1505M v5 suits a buyer who wants a cheap, well-built used workstation for engineering or office software: quad-core throughput, ECC support and a 261st-place rank out of 741 chips, in machines priced around $300–$390 in this catalog. It is not a gaming pick — 35 of 69 games at the recommended tier is mid-table coverage, and the GPUs in these machines age faster than the CPU. For memory-sensitive workstation duty on a tight budget, it remains a rational choice.
