Core 2 Duo T6570 vs Xeon E3-1220L Performance Spectrum

About PassMark

PassMark CPU Mark evaluates processor speed through complex mathematical computations. It provides a reliable metric to compare multi-core performance, where higher scores indicate faster processing for multitasking, gaming, and heavy workloads.

Core 2 Duo T6570 vs Xeon E3-1220L: 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 T6570

2009

Why buy it

  • +0.5% higher PassMark.
  • Draws 2W instead of 20W, a 18W reduction.

Trade-offs

  • Smaller total L3 cache (2 MB vs 3 MB).
  • Less compelling for workstation-style loads than Xeon E3-1220L, which brings 2 cores / 4 threads.

Xeon E3-1220L

2011

Why buy it

  • +50% larger total L3 cache (3 MB vs 2 MB).
  • Better for workstations and heavier parallel workloads: 2 cores / 4 threads.

Trade-offs

  • Lower PassMark (2,263 vs 2,274).
  • Launch MSRP is still $189 MSRP, while Core 2 Duo T6570 mostly shows up through inconsistent older-market listings.
  • 900% higher power demand at 20W vs 2W.

Quick Answers

So, is Xeon E3-1220L better than Core 2 Duo T6570?
Not really, because they are built for different jobs. Xeon E3-1220L makes more sense for workstation-style multi-core throughput, while Core 2 Duo T6570 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, Core 2 Duo T6570 is the stronger fit. You are getting 0.5% better PassMark, backed by 2 cores and 2 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Xeon E3-1220L is the better buy right now. Xeon E3-1220L comes in at an unclear MSRP at $189 MSRP versus unclear MSRP, and it still gives you a 0.7% average FPS lead across 9 shared CPU game tests in our data. The compromise is that Core 2 Duo T6570 is still stronger for heavier multi-core work with 0.5% better PassMark. It is also 100.0% better value on MSRP (12.0 vs 0.0 PassMark/$), 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 E3-1220L makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2009) and 50% larger total L3 cache (3 MB vs 2 MB). That makes it the safer long-term bet.
