Celeron B800 vs Xeon E5507: Pros, Cons & Final Verdict

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

Celeron B800

2011

Why buy it

  • βœ…Draws 35W instead of 80W, a 45W reduction.
  • βœ…100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • βœ…Integrated graphics onboard with HD Graphics (Sandy Bridge), while Xeon E5507 needs a discrete GPU.

Trade-offs

  • ❌Smaller total L3 cache (2 MB vs 4 MB).
  • ❌Less compelling for workstation-style loads than Xeon E5507, which brings 4 cores / 4 threads.
  • ❌Launch MSRP is still $80 MSRP, while Xeon E5507 mostly shows up through inconsistent older-market listings.

Xeon E5507

2010

Why buy it

  • βœ…+100% larger total L3 cache (4 MB vs 2 MB).
  • βœ…Better for workstations and heavier parallel workloads: 4 cores / 4 threads.

Trade-offs

  • ❌Lower PassMark (1,905 vs 1,910).
  • ❌128.6% higher power demand at 80W vs 35W.
  • ❌No integrated graphics, while Celeron B800 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Celeron B800 better than Xeon E5507?
Not really, because they are built for different jobs. Xeon E5507 makes more sense for workstation-style multi-core throughput, while Celeron B800 is the more practical desktop choice for gaming, platform cost, and everyday use.
Which one is better for gaming?
If gaming is the priority, Celeron B800 is the better pick. According to our tests, it delivers 1.4% 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, Celeron B800 is the stronger fit. You are getting 0.3% better PassMark, backed by 2 cores and 2 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Celeron B800 is the better buy right now. Celeron B800 comes in at an unclear MSRP at $80 MSRP versus unclear MSRP, and it still gives you a 1.4% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (23.9 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
Which one is more future-proof for 2026 and beyond?
Celeron B800 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2010) and more multi-core headroom with 2 cores / 2 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
