A6-5345M

2013

Why buy it

✅Draws 17W instead of 65W, a 48W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Radeon HD 8410G, while Xeon 5120 needs a discrete GPU.

Trade-offs

❌Fewer obvious downsides in this matchup outside of normal market pricing swings.

Xeon 5120

2006

Why buy it

Trade-offs

❌Lower PassMark (1,115 vs 1,122).
❌Launch MSRP is still $107 MSRP, while A6-5345M mostly shows up through inconsistent older-market listings.
❌282.4% higher power demand at 65W vs 17W.
❌No integrated graphics, while A6-5345M can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is A6-5345M better than Xeon 5120?

Not really, because they are built for different jobs. Xeon 5120 makes more sense for workstation-style multi-core throughput, while A6-5345M is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, A6-5345M is the better pick. According to our tests, it delivers 0.1% 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, A6-5345M is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 2 threads.

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

A6-5345M is still the faster CPU overall, but Xeon 5120 is easier to justify if budget matters more than peak performance. A6-5345M comes in at an unclear MSRP at unclear MSRP versus $107 MSRP, and it still gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data. Xeon 5120 is also 100.0% better value on MSRP (10.4 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

A6-5345M makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2006) and more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
