Atom x7213RE

2024

Why buy it

✅Draws 9W instead of 80W, a 71W reduction.
✅Newer platform on FCBGA1264 with DDR5 support instead of LGA1366 and older memory support.
✅100+% more PCIe lanes (9 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel UHD Graphics (16EU), while Xeon E5520 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon E5520 across 50 shared CPU benchmark tests.
❌Lower PassMark (2,538 vs 2,541).
❌Smaller total L3 cache (6 MB vs 8 MB).
❌Less compelling for workstation-style loads than Xeon E5520, which brings 4 cores / 8 threads.

Xeon E5520

2009

Why buy it

✅Better for gaming: +9.2% higher average FPS across 50 shared CPU benchmark tests.
✅+33.3% larger total L3 cache (8 MB vs 6 MB).
✅Better for workstations and heavier parallel workloads: 4 cores / 8 threads.

Trade-offs

❌788.9% higher power demand at 80W vs 9W.
❌Older platform position on LGA1366, while Atom x7213RE moves to FCBGA1264 and DDR5.
❌No integrated graphics, while Atom x7213RE can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Xeon E5520 better than Atom x7213RE?

Not really, because they are built for different jobs. Xeon E5520 makes more sense for workstation-style multi-core throughput, while Atom x7213RE 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 E5520 is the better pick. According to our tests, it delivers 9.2% 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, Xeon E5520 is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

Xeon E5520 still makes the most sense overall. Xeon E5520 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 9.2% average FPS lead across 50 shared CPU game tests in our data.

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

Atom x7213RE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2024 vs 2009) and a healthier platform with FCBGA1264 and DDR5 instead of LGA1366. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
