Core i5-8500B vs Xeon E3-1240 v6: Pros, Cons & Final Verdict

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

Core i5-8500B

2018

Why buy it

  • +1.9% higher PassMark.
  • Draws 65W instead of 72W, a 7W reduction.
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with UHD Graphics 630, while Xeon E3-1240 v6 needs a discrete GPU.

Trade-offs

  • Worse for gaming: lower average FPS than Xeon E3-1240 v6 across 50 shared CPU benchmark tests.
  • Less compelling for workstation-style loads than Xeon E3-1240 v6, which brings 4 cores / 8 threads.
  • Launch MSRP is still $192 MSRP, while Xeon E3-1240 v6 mostly shows up through inconsistent older-market listings.

Xeon E3-1240 v6

2017

Why buy it

  • Better for gaming: +12.1% higher average FPS across 50 shared CPU benchmark tests.
  • Better for workstations and heavier parallel workloads: 4 cores / 8 threads.

Trade-offs

  • Lower PassMark (8,731 vs 8,900).
  • No integrated graphics, while Core i5-8500B can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i5-8500B better than Xeon E3-1240 v6?
Not really, because they are built for different jobs. Xeon E3-1240 v6 makes more sense for workstation-style multi-core throughput, while Core i5-8500B is the more practical desktop choice for gaming, platform cost, and everyday use.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i5-8500B is the stronger fit. You are getting 1.9% better PassMark, backed by 6 cores and 6 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-8500B is the better buy right now. Core i5-8500B comes in at an unclear MSRP at $192 MSRP versus unclear MSRP, and it still gives you 1.9% better PassMark. The compromise is that Xeon E3-1240 v6 is still the better pure gaming CPU with a 12.1% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (46.4 vs 0.0 PassMark/$), 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 i5-8500B makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2017) and more multi-core headroom with 6 cores / 6 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
