Core i7-2670QM vs Xeon L5638: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Core i7-2670QM

2011

Why buy it

✅Draws 45W instead of 60W, a 15W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics 3000, while Xeon L5638 needs a discrete GPU.

Trade-offs

❌Smaller total L3 cache (6 MB vs 12 MB).
❌Less compelling for workstation-style loads than Xeon L5638, which brings 6 cores / 12 threads.

Xeon L5638

2010

Why buy it

✅+100% larger total L3 cache (12 MB vs 6 MB).
✅Better for workstations and heavier parallel workloads: 6 cores / 12 threads.

Trade-offs

❌Lower PassMark (3,707 vs 3,748).
❌33.3% higher power demand at 60W vs 45W.
❌No integrated graphics, while Core i7-2670QM can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i7-2670QM better than Xeon L5638?

Not really, because they are built for different jobs. Xeon L5638 makes more sense for workstation-style multi-core throughput, while Core i7-2670QM is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Core i7-2670QM is the better pick. According to our tests, it delivers 1.1% more average FPS across 50 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Core i7-2670QM is the stronger fit. You are getting 1.1% better PassMark, backed by 4 cores and 8 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Core i7-2670QM still makes the most sense overall. Core i7-2670QM comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 1.1% average FPS lead across 50 shared CPU game tests in our data.

Which one is more future-proof for 2026 and beyond?

Core i7-2670QM makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2010) and more multi-core headroom with 4 cores / 8 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
