M3 Pro 12-Core vs Xeon E5-2679 v4: Pros, Cons & Final Verdict

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

M3 Pro 12-Core

2023

Why buy it

✅Newer platform on none with DDR5 support instead of LGA2011-3 and DDR4.

Trade-offs

❌Less compelling for workstation-style loads than Xeon E5-2679 v4, which brings 20 cores / 40 threads and 40 PCIe lanes.

Xeon E5-2679 v4

2016

Why buy it

✅Better for workstations and heavier parallel workloads: 20 cores / 40 threads, plus 40 PCIe lanes vs 0.
✅100+% more PCIe lanes (40 vs 0) for storage and expansion-heavy builds.

Trade-offs

❌Lower PassMark (24,131 vs 24,170).
❌Launch MSRP is still $2,702 MSRP, while M3 Pro 12-Core mostly shows up through inconsistent older-market listings.
❌Older platform position on LGA2011-3 with DDR4, while M3 Pro 12-Core moves to none and DDR5.

Quick Answers

So, is M3 Pro 12-Core better than Xeon E5-2679 v4?

Not really, because they are built for different jobs. Xeon E5-2679 v4 makes more sense for workstation-style multi-core throughput, while M3 Pro 12-Core is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, M3 Pro 12-Core is the better pick. According to our tests, it delivers 1.9% 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, M3 Pro 12-Core is the stronger fit. You are getting 0.2% better PassMark, backed by 12 cores and 12 threads.

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

M3 Pro 12-Core is still the faster CPU overall, but Xeon E5-2679 v4 is easier to justify if budget matters more than peak performance. M3 Pro 12-Core comes in at an unclear MSRP at unclear MSRP versus $2,702 MSRP, and it still gives you a 1.9% average FPS lead across 50 shared CPU game tests in our data. Xeon E5-2679 v4 is also 100.0% better value on MSRP (8.9 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.

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

M3 Pro 12-Core makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2016), a healthier platform with none and DDR5 instead of LGA2011-3, and more multi-core headroom with 12 cores / 12 threads instead of 20/40. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
