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

Athlon II X4 645

2010

Why buy it

✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Includes a boxed cooler (Yes), unlike Xeon L3360.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon L3360 across 34 shared CPU benchmark tests.
❌Lower PassMark (2,375 vs 2,412).
❌Launch MSRP is still $126 MSRP, while Xeon L3360 mostly shows up through inconsistent older-market listings.
❌46.2% higher power demand at 95W vs 65W.

Xeon L3360

2009

Why buy it

✅Better for gaming: +4.6% higher average FPS across 34 shared CPU benchmark tests.
✅Draws 65W instead of 95W, a 30W reduction.

Trade-offs

❌No boxed cooler included, unlike Athlon II X4 645.

Quick Answers

So, is Xeon L3360 better than Athlon II X4 645?

Not really, because they are built for different jobs. Xeon L3360 makes more sense for workstation-style multi-core throughput, while Athlon II X4 645 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 L3360 is the better pick. According to our tests, it delivers 4.6% more average FPS across 34 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Xeon L3360 is the stronger fit. You are getting 1.6% better PassMark.

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

Xeon L3360 is still the much better call for a fresh build. Xeon L3360 comes in at an unclear MSRP at unclear MSRP versus $126 MSRP, and it still gives you a 4.6% average FPS lead across 34 shared CPU game tests in our data. Athlon II X4 645 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (18.8 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on AM3.

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

Athlon II X4 645 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2009). That makes it the safer long-term bet.
