Core i5-560UM vs Pentium E5400: Pros, Cons & Final Verdict

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

Core i5-560UM

2010

Why buy it

✅+0.8% higher PassMark.
✅Draws 18W instead of 65W, a 47W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics (Ironlake), while Pentium E5400 needs a discrete GPU.

Trade-offs

❌Lower PassMark per dollar, at 4.1 vs 18.3 PassMark/$ ($250 MSRP vs $55 MSRP).

Pentium E5400

2009

Why buy it

✅Costs $195 less on MSRP ($55 MSRP vs $250 MSRP).
✅Delivers 351.0% more PassMark for each dollar spent, at 18.3 vs 4.1 PassMark/$ ($55 MSRP vs $250 MSRP).

Trade-offs

❌Lower PassMark (1,007 vs 1,015).
❌261.1% higher power demand at 65W vs 18W.
❌No integrated graphics, while Core i5-560UM can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i5-560UM better than Pentium E5400?

It depends on what you want from the system. For gaming, Pentium E5400 is ahead with a 2.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-560UM pulls ahead with 0.8% better PassMark.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Core i5-560UM is the stronger fit. You are getting 0.8% better PassMark, backed by 2 cores and 4 threads.

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

Core i5-560UM is still the much better call for a fresh build. Core i5-560UM comes in 354.5% more expensive on MSRP at $250 MSRP versus $55 MSRP, and it still gives you 0.8% better PassMark. Pentium E5400 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 351.0% better value on paper (18.3 vs 4.1 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA775.

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

Core i5-560UM makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2009) and more multi-core headroom with 2 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
