Core 2 Duo P8800 vs Xeon W3520: Pros, Cons & Final Verdict

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

Core 2 Duo P8800

2009

Why buy it

  • Draws 3W instead of 130W, a 127W reduction.

Trade-offs

  • Worse for gaming: lower average FPS than Xeon W3520 across 50 shared CPU benchmark tests.
  • Lower PassMark (2,932 vs 2,940).
  • Smaller total L3 cache (3 MB vs 8 MB).
  • Less compelling for workstation-style loads than Xeon W3520, which brings 4 cores / 8 threads.

Xeon W3520

2009

Why buy it

  • Better for gaming: +12.5% higher average FPS across 50 shared CPU benchmark tests.
  • +166.7% larger total L3 cache (8 MB vs 3 MB).
  • Better for workstations and heavier parallel workloads: 4 cores / 8 threads.

Trade-offs

  • Launch MSRP is still $284 MSRP, while Core 2 Duo P8800 mostly shows up through inconsistent older-market listings.
  • 4233.3% higher power demand at 130W vs 3W.

Quick Answers

So, is Xeon W3520 better than Core 2 Duo P8800?
Not really, because they are built for different jobs. Xeon W3520 makes more sense for workstation-style multi-core throughput, while Core 2 Duo P8800 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 W3520 is the better pick. According to our tests, it delivers 12.5% 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 W3520 is the stronger fit. You are getting 0.3% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 166.7% larger total L3 cache (8 MB vs 3 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Xeon W3520 is the better buy right now. Xeon W3520 comes in at an unclear MSRP at $284 MSRP versus unclear MSRP, and it still gives you a 12.5% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (10.4 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
Which one is more future-proof for 2026 and beyond?
Xeon W3520 makes more sense long term for 2026 and beyond. You are getting 166.7% larger total L3 cache (8 MB vs 3 MB) and more multi-core headroom with 4 cores / 8 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
