Quick Answers

So, is Atom x7-E3950 better than Pentium 1403?

Yes. Atom x7-E3950 is the better all-around CPU here. It gives you a 4.7% average FPS lead across 50 shared CPU game tests in our data, 0.7% 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, Atom x7-E3950 is the better pick. According to our tests, it delivers 4.7% 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, Atom x7-E3950 is the stronger fit. You are getting 0.7% better PassMark, backed by 4 cores and 4 threads.

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

Atom x7-E3950 still makes the most sense overall. Atom x7-E3950 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 4.7% average FPS lead across 50 shared CPU game tests in our data.

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

Atom x7-E3950 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2016 vs 2012) and more multi-core headroom with 4 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.
