Core i7-640M vs Xeon X3320: Pros, Cons & Final Verdict

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

Core i7-640M

2010

Why buy it

✅+0.5% higher PassMark.
✅Draws 35W instead of 95W, a 60W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics (Ironlake), while Xeon X3320 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon X3320 across 50 shared CPU benchmark tests.
❌Smaller total L3 cache (4 MB vs 6 MB).

Xeon X3320

2008

Why buy it

✅Better for gaming: +5.5% higher average FPS across 50 shared CPU benchmark tests.
✅+50% larger total L3 cache (6 MB vs 4 MB).

Trade-offs

❌Lower PassMark (2,082 vs 2,092).
❌171.4% higher power demand at 95W vs 35W.
❌No integrated graphics, while Core i7-640M can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i7-640M better than Xeon X3320?

Not really, because they are built for different jobs. Xeon X3320 makes more sense for workstation-style multi-core throughput, while Core i7-640M is the more practical desktop choice for gaming, platform cost, and everyday use.

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

For streaming, content creation, and heavier multitasking, Core i7-640M is the stronger fit. You are getting 0.5% better PassMark, backed by 2 cores and 4 threads.

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

Core i7-640M still makes the most sense overall. Core i7-640M comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.5% better PassMark.

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

Core i7-640M makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2008). That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
