E2-3800 vs Xeon W3503: Pros, Cons & Final Verdict

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

E2-3800

2013

Why buy it

✅+1% higher PassMark.
✅Draws 15W instead of 130W, a 115W reduction.
✅100+% more PCIe lanes (4 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Radeon HD 8280, while Xeon W3503 needs a discrete GPU.

Trade-offs

❌Launch MSRP is still $100 MSRP, while Xeon W3503 mostly shows up through inconsistent older-market listings.

Xeon W3503

2009

Why buy it

Trade-offs

❌Lower PassMark (1,125 vs 1,136).
❌766.7% higher power demand at 130W vs 15W.
❌No integrated graphics, while E2-3800 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is E2-3800 better than Xeon W3503?

Not really, because they are built for different jobs. Xeon W3503 makes more sense for workstation-style multi-core throughput, while E2-3800 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, E2-3800 is the stronger fit. You are getting 1% better PassMark, backed by 4 cores and 4 threads.

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

E2-3800 is the better buy right now. E2-3800 comes in at an unclear MSRP at $100 MSRP versus unclear MSRP, and it still gives you 1% better PassMark. The compromise is that Xeon W3503 is still the better pure gaming CPU with a 1.9% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (11.4 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

E2-3800 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2009) and more multi-core headroom with 4 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
