Core i3-4350T

2014

Why buy it

✅Draws 35W instead of 512W, a 477W reduction.
✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with HD Graphics 4600, while Core i7-5557U needs a discrete GPU.

Trade-offs

❌Lower PassMark (3,142 vs 3,153).
❌Launch MSRP is still $138 MSRP, while Core i7-5557U mostly shows up through inconsistent older-market listings.

Core i7-5557U

2015

Why buy it

Trade-offs

❌1362.9% higher power demand at 512W vs 35W.
❌No integrated graphics, while Core i3-4350T can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i7-5557U better than Core i3-4350T?

Yes. Core i7-5557U is the better all-around CPU here. It gives you a 0.4% average FPS lead across 50 shared CPU game tests in our data, 0.4% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i7-5557U is the better pick. According to our tests, it delivers 0.4% 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, Core i7-5557U is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 4 threads.

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

Core i7-5557U is still the much better call for a fresh build. Core i7-5557U comes in at an unclear MSRP at unclear MSRP versus $138 MSRP, and it still gives you a 0.4% average FPS lead across 50 shared CPU game tests in our data. Core i3-4350T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2014 platform. Even with 100.0% better value on paper (22.8 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1150.

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

Core i7-5557U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2014) 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.
