Core i5-6440EQ vs Xeon E3-1240: Pros, Cons & Final Verdict

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

Core i5-6440EQ

2015

Why buy it

  • Costs $23 less on MSRP ($250 MSRP vs $273 MSRP).
  • Delivers 8.5% more PassMark for each dollar spent, at 21.3 vs 19.6 PassMark/$ ($250 MSRP vs $273 MSRP).
  • 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 E3-1240 needs a discrete GPU.

Trade-offs

  • Worse for gaming: lower average FPS than Xeon E3-1240 across 50 shared CPU benchmark tests.
  • Lower PassMark (5,329 vs 5,361).
  • Smaller total L3 cache (6 MB vs 8 MB).
  • Less compelling for workstation-style loads than Xeon E3-1240, which brings 4 cores / 8 threads.

Xeon E3-1240

2011

Why buy it

  • Better for gaming: +14.4% higher average FPS across 50 shared CPU benchmark tests.
  • +33.3% larger total L3 cache (8 MB vs 6 MB).
  • Better for workstations and heavier parallel workloads: 4 cores / 8 threads.

Trade-offs

  • Lower PassMark per dollar, at 19.6 vs 21.3 PassMark/$ ($273 MSRP vs $250 MSRP).
  • 77.8% higher power demand at 80W vs 45W.
  • No integrated graphics, while Core i5-6440EQ can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Xeon E3-1240 better than Core i5-6440EQ?
Not really, because they are built for different jobs. Xeon E3-1240 makes more sense for workstation-style multi-core throughput, while Core i5-6440EQ 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 E3-1240 is the better pick. According to our tests, it delivers 14.4% 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 E3-1240 is the stronger fit. You are getting 0.6% better PassMark, backed by 4 cores and 8 threads. It also has the larger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Xeon E3-1240 is still the much better call for a fresh build. Xeon E3-1240 comes in 9.2% more expensive on MSRP at $273 MSRP versus $250 MSRP, and it still gives you a 14.4% average FPS lead across 50 shared CPU game tests in our data. Core i5-6440EQ only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2015 platform. Even with 8.5% better value on paper (21.3 vs 19.6 PassMark/$), 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 i5-6440EQ makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2011). That makes it the safer long-term bet.
