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

Atom x7405C

2024

Why buy it

✅+0.8% higher PassMark.
✅Draws 12W instead of 80W, a 68W reduction.
✅Newer platform on FCBGA1264 with DDR5 support instead of LGA1150 and DDR4.
✅100+% more PCIe lanes (9 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel UHD Graphics, while Xeon E3-1220 v3 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon E3-1220 v3 across 50 shared CPU benchmark tests.
❌Smaller total L3 cache (6 MB vs 8 MB).

Xeon E3-1220 v3

2013

Why buy it

✅Better for gaming: +3.8% higher average FPS across 50 shared CPU benchmark tests.
✅+33.3% larger total L3 cache (8 MB vs 6 MB).

Trade-offs

❌Lower PassMark (5,178 vs 5,218).
❌Launch MSRP is still $203 MSRP, while Atom x7405C mostly shows up through inconsistent older-market listings.
❌566.7% higher power demand at 80W vs 12W.
❌Older platform position on LGA1150 with DDR4, while Atom x7405C moves to FCBGA1264 and DDR5.
❌No integrated graphics, while Atom x7405C can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Atom x7405C better than Xeon E3-1220 v3?

Not really, because they are built for different jobs. Xeon E3-1220 v3 makes more sense for workstation-style multi-core throughput, while Atom x7405C 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, Atom x7405C is the stronger fit. You are getting 0.8% better PassMark, backed by 4 cores and 4 threads.

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

Atom x7405C is still the faster CPU overall, but Xeon E3-1220 v3 is easier to justify if budget matters more than peak performance. Atom x7405C comes in at an unclear MSRP at unclear MSRP versus $203 MSRP, and it still gives you 0.8% better PassMark. The compromise is that Xeon E3-1220 v3 is still the better pure gaming CPU with a 3.8% average FPS lead across 50 shared CPU game tests in our data. Xeon E3-1220 v3 is also 100.0% better value on MSRP (25.5 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

Atom x7405C makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2013), a healthier platform with FCBGA1264 and DDR5 instead of LGA1150, and more multi-core headroom with 4 cores / 4 threads instead of 4/4. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
