Quick Answers

So, is Pentium 4405Y better than Pentium 987?

Yes. Pentium 4405Y is the better all-around CPU here. It gives you a 0.3% average FPS lead across 19 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?

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, Pentium 4405Y 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 4405Y is the easy recommendation for a fresh desktop build. Pentium 4405Y comes in at an unclear MSRP at unclear MSRP versus $134 MSRP, and it still gives you a 0.3% average FPS lead across 19 shared CPU game tests in our data. Pentium 987 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 0.3% in the shared gaming data.

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

Pentium 4405Y makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2013) 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.
