  • Launch MSRP is still $225 MSRP, while Core i5-4278U mostly shows up through inconsistent older-market listings.

Core i5-4278U

2014

Why buy it

  • +0.6% higher PassMark.

Trade-offs

  • Fewer obvious downsides in this matchup outside of normal market pricing swings.

Quick Answers

So, is Core i5-4278U better than Core i5-4200M?
Yes. Core i5-4278U is the better all-around CPU here. It gives you a 0.5% average FPS lead across 50 shared CPU game tests in our data, 0.6% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.
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 i5-4278U is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 4 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-4278U is still the much better call for a fresh build. Core i5-4278U comes in at an unclear MSRP at unclear MSRP versus $225 MSRP, and it still gives you a 0.5% average FPS lead across 50 shared CPU game tests in our data. Core i5-4200M only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2013 platform. Even with 100.0% better value on paper (12.5 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA946.
Which one is more future-proof for 2026 and beyond?
Core i5-4278U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2013) and more multi-core headroom with 2 cores / 4 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
