Core i5-670 vs Xeon X3380: Pros, Cons & Final Verdict

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

Core i5-670

2010

Why buy it

✅Draws 73W instead of 95W, a 22W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics, while Xeon X3380 needs a discrete GPU.
✅Includes a boxed cooler (Yes), unlike Xeon X3380.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon X3380 across 48 shared CPU benchmark tests.
❌Lower PassMark (2,553 vs 2,568).
❌Smaller total L3 cache (4 MB vs 12 MB).
❌Launch MSRP is still $284 MSRP, while Xeon X3380 mostly shows up through inconsistent older-market listings.

Xeon X3380

2009

Why buy it

✅Better for gaming: +8.7% higher average FPS across 48 shared CPU benchmark tests.
✅+200% larger total L3 cache (12 MB vs 4 MB).

Trade-offs

❌30.1% higher power demand at 95W vs 73W.
❌No integrated graphics, while Core i5-670 can still boot and troubleshoot without a discrete GPU.
❌No boxed cooler included, unlike Core i5-670.

Quick Answers

So, is Xeon X3380 better than Core i5-670?

Not really, because they are built for different jobs. Xeon X3380 makes more sense for workstation-style multi-core throughput, while Core i5-670 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Xeon X3380 is the better pick. According to our tests, it delivers 8.7% more average FPS across 48 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Xeon X3380 is the stronger fit. You are getting 0.6% better PassMark. It also has the larger cache pool with 200% larger total L3 cache (12 MB vs 4 MB).

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

Xeon X3380 is still the much better call for a fresh build. Xeon X3380 comes in at an unclear MSRP at unclear MSRP versus $284 MSRP, and it still gives you a 8.7% average FPS lead across 48 shared CPU game tests in our data. Core i5-670 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (9.0 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1156.

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

Core i5-670 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2009). That makes it the safer long-term bet.
