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

Core i7-660UM

2010

Why buy it

✅Draws 18W instead of 35W, a 17W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics, while Pentium Dual Core T4400 needs a discrete GPU.

Trade-offs

❌Lower PassMark (1,279 vs 1,284).
❌Lower PassMark per dollar, at 4.0 vs 12.0 PassMark/$ ($317 MSRP vs $107 MSRP).

Pentium Dual Core T4400

2009

Why buy it

✅+0.4% higher PassMark.
✅Costs $210 less on MSRP ($107 MSRP vs $317 MSRP).
✅Delivers 197.4% more PassMark for each dollar spent, at 12.0 vs 4.0 PassMark/$ ($107 MSRP vs $317 MSRP).

Trade-offs

❌94.4% higher power demand at 35W vs 18W.
❌No integrated graphics, while Core i7-660UM can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i7-660UM better than Pentium Dual Core T4400?

It depends on what you want from the system. For gaming, Core i7-660UM is ahead with a 2.5% average FPS lead across 46 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Pentium Dual Core T4400 pulls ahead with 0.4% better PassMark.

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

For streaming, content creation, and heavier multitasking, Pentium Dual Core T4400 is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 2 threads.

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

Core i7-660UM is still the much better call for a fresh build. Core i7-660UM comes in 196.3% more expensive on MSRP at $317 MSRP versus $107 MSRP, and it still gives you a 2.5% average FPS lead across 46 shared CPU game tests in our data. Pentium Dual Core T4400 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 197.4% better value on paper (12.0 vs 4.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on P.

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

Core i7-660UM makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2009). That makes it the safer long-term bet.
