Core Duo T2700

2006

Why buy it

✅Draws 2W instead of 80W, a 78W reduction.

Trade-offs

❌Lower PassMark (1,860 vs 1,868).
❌Less compelling for workstation-style loads than Xeon E5345, which brings 4 cores / 4 threads.
❌Launch MSRP is still $663 MSRP, while Xeon E5345 mostly shows up through inconsistent older-market listings.

Xeon E5345

2006

Why buy it

✅+0.4% higher PassMark.
✅Better for workstations and heavier parallel workloads: 4 cores / 4 threads.

Trade-offs

Quick Answers

So, is Core Duo T2700 better than Xeon E5345?

Not really, because they are built for different jobs. Xeon E5345 makes more sense for workstation-style multi-core throughput, while Core Duo T2700 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, Xeon E5345 is the stronger fit. You are getting 0.4% better PassMark, backed by 4 cores and 4 threads.

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

Core Duo T2700 is the better buy right now. Core Duo T2700 comes in at an unclear MSRP at $663 MSRP versus unclear MSRP, and it still gives you a 0.0% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Xeon E5345 is still stronger for heavier multi-core work with 0.4% better PassMark. It is also 100.0% better value on MSRP (2.8 vs 0.0 PassMark/$), 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 E5345 makes more sense long term for 2026 and beyond. You are getting 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.
