Quick Answers

So, is Pentium D 940 better than Celeron 877?

Yes. Pentium D 940 is the better all-around CPU here. It gives you a 11.5% average FPS lead across 50 shared CPU game tests in our data and 8.7% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Pentium D 940 is the better pick. According to our tests, it delivers 11.5% 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, Pentium D 940 is the stronger fit. You are getting 8.7% better PassMark, backed by 2 cores and 2 threads.

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

Pentium D 940 is the easy recommendation for a fresh desktop build. Pentium D 940 comes in 53.5% more expensive on MSRP at $132 MSRP versus $86 MSRP, and it still gives you a 11.5% average FPS lead across 50 shared CPU game tests in our data. Celeron 877 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 11.5% in the shared gaming data.

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

Celeron 877 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2006). That makes it the safer long-term bet.
