Xeon E3-1286 v3

2014

Why buy it

  • Draws 84W instead of 100W, a 16W reduction.

Trade-offs

  • Lower PassMark (7,879 vs 7,934).

Quick Answers

So, is Core i7-8709G better than Xeon E3-1286 v3?
Not really, because they are built for different jobs. Xeon E3-1286 v3 makes more sense for workstation-style multi-core throughput, while Core i7-8709G is the more practical desktop choice for gaming, platform cost, and everyday use.
Which one is better for gaming?
For gaming, this matchup is basically a tie in the data we have.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i7-8709G is the stronger fit. You are getting 0.7% better PassMark, backed by 4 cores and 8 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i7-8709G is the better buy right now. Core i7-8709G comes in at an unclear MSRP at $338 MSRP versus unclear MSRP, and it still gives you a 2.7% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (23.5 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
Which one is more future-proof for 2026 and beyond?
Core i7-8709G makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2014) and more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
