Quick Answers

So, is Pentium Gold 4425Y better than Pentium 1403?

Yes. Pentium Gold 4425Y is the better all-around CPU here. It gives you a 0.1% average FPS lead across 49 shared CPU game tests in our data, 0.2% 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, Pentium Gold 4425Y is the better pick. According to our tests, it delivers 0.1% more average FPS across 49 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Pentium Gold 4425Y is the stronger fit. You are getting 0.2% better PassMark, backed by 2 cores and 4 threads.

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

Pentium Gold 4425Y still makes the most sense overall. Pentium Gold 4425Y comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 0.1% average FPS lead across 49 shared CPU game tests in our data.

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

Pentium Gold 4425Y makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2012) 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.
