Core i5-7Y57 vs Xeon E5450: Pros, Cons & Final Verdict

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

Core i5-7Y57

2017

Why buy it

✅+0.2% higher PassMark.
✅Draws 5W instead of 80W, a 76W reduction.
✅100+% more PCIe lanes (12 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics 615, while Xeon E5450 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon E5450 across 50 shared CPU benchmark tests.
❌Smaller total L3 cache (4 MB vs 12 MB).
❌Less compelling for workstation-style loads than Xeon E5450, which brings 4 cores / 4 threads.
❌Launch MSRP is still $281 MSRP, while Xeon E5450 mostly shows up through inconsistent older-market listings.

Xeon E5450

2007

Why buy it

✅Better for gaming: +5.7% higher average FPS across 50 shared CPU benchmark tests.
✅+200% larger total L3 cache (12 MB vs 4 MB).
✅Better for workstations and heavier parallel workloads: 4 cores / 4 threads.

Trade-offs

❌Lower PassMark (2,581 vs 2,585).
❌1677.8% higher power demand at 80W vs 4.5W.
❌No integrated graphics, while Core i5-7Y57 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i5-7Y57 better than Xeon E5450?

Not really, because they are built for different jobs. Xeon E5450 makes more sense for workstation-style multi-core throughput, while Core i5-7Y57 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 i5-7Y57 is the stronger fit. You are getting 0.2% better PassMark, backed by 2 cores and 4 threads.

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

Core i5-7Y57 is the better buy right now. Core i5-7Y57 comes in at an unclear MSRP at $281 MSRP versus unclear MSRP, and it still gives you 0.2% better PassMark. The compromise is that Xeon E5450 is still the better pure gaming CPU with a 5.7% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (9.2 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core i5-7Y57 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2007) and more multi-core headroom with 2 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
