Core i7-6820EQ vs Xeon E3-1231 v3: Pros, Cons & Final Verdict

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

Core i7-6820EQ

2015

Why buy it

  • Draws 45W instead of 80W, a 35W reduction.
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with HD Graphics 530, while Xeon E3-1231 v3 needs a discrete GPU.

Trade-offs

  • Worse for gaming: lower average FPS than Xeon E3-1231 v3 across 50 shared CPU benchmark tests.
  • Lower PassMark (7,025 vs 7,031).
  • Launch MSRP is still $378 MSRP, while Xeon E3-1231 v3 mostly shows up through inconsistent older-market listings.

Xeon E3-1231 v3

2014

Why buy it

  • Better for gaming: +8.5% higher average FPS across 50 shared CPU benchmark tests.

Trade-offs

  • 77.8% higher power demand at 80W vs 45W.
  • No integrated graphics, while Core i7-6820EQ can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Xeon E3-1231 v3 better than Core i7-6820EQ?
Not really, because they are built for different jobs. Xeon E3-1231 v3 makes more sense for workstation-style multi-core throughput, while Core i7-6820EQ 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 E3-1231 v3 is the better pick. According to our tests, it delivers 8.5% 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, Xeon E3-1231 v3 is the stronger fit. You are getting 0.1% better PassMark, backed by 4 cores and 8 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Xeon E3-1231 v3 is still the much better call for a fresh build. Xeon E3-1231 v3 comes in at an unclear MSRP at unclear MSRP versus $378 MSRP, and it still gives you a 8.5% average FPS lead across 50 shared CPU game tests in our data. Core i7-6820EQ only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2015 platform. Even with 100.0% better value on paper (18.6 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on that older DDR4-era platform.
Which one is more future-proof for 2026 and beyond?
Core i7-6820EQ makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2014). That makes it the safer long-term bet.
