Core i7-3770S vs Xeon X5670: Pros, Cons & Final Verdict

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

Core i7-3770S

2012

Why buy it

✅Draws 65W instead of 95W, a 30W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics 4000, while Xeon X5670 needs a discrete GPU.
✅Includes a boxed cooler (Stock), unlike Xeon X5670.

Trade-offs

❌Smaller total L3 cache (8 MB vs 12 MB).
❌Less compelling for workstation-style loads than Xeon X5670, which brings 6 cores / 12 threads.
❌Lower PassMark per dollar, at 24.7 vs 91.9 PassMark/$ ($250 MSRP vs $67 MSRP).

Xeon X5670

2010

Why buy it

✅+50% larger total L3 cache (12 MB vs 8 MB).
✅Better for workstations and heavier parallel workloads: 6 cores / 12 threads.
✅Costs $183 less on MSRP ($67 MSRP vs $250 MSRP).
✅Delivers 272.3% more PassMark for each dollar spent, at 91.9 vs 24.7 PassMark/$ ($67 MSRP vs $250 MSRP).

Trade-offs

❌Lower PassMark (6,160 vs 6,173).
❌46.2% higher power demand at 95W vs 65W.

Quick Answers

So, is Core i7-3770S better than Xeon X5670?

Not really, because they are built for different jobs. Xeon X5670 makes more sense for workstation-style multi-core throughput, while Core i7-3770S 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 i7-3770S is the better pick. According to our tests, it delivers 1.5% 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 i7-3770S is the stronger fit. You are getting 0.2% better PassMark, backed by 4 cores and 8 threads.

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

Core i7-3770S is still the faster CPU overall, but Xeon X5670 is easier to justify if budget matters more than peak performance. Core i7-3770S comes in 273.1% more expensive on MSRP at $250 MSRP versus $67 MSRP, and it still gives you a 1.5% average FPS lead across 50 shared CPU game tests in our data. Xeon X5670 is also 272.3% better value on MSRP (91.9 vs 24.7 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Core i7-3770S makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 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.
