Quick Answers

So, is Pentium D 950 better than Celeron P4505?

Yes. Pentium D 950 is the better all-around CPU here. It gives you a 2.0% average FPS lead across 50 shared CPU game tests in our data and 1.9% 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 950 is the better pick. According to our tests, it delivers 2.0% 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 950 is the stronger fit. You are getting 1.9% better PassMark, backed by 2 cores and 2 threads.

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

Pentium D 950 is the easy recommendation for a fresh desktop build. Pentium D 950 comes in 640.7% more expensive on MSRP at $637 MSRP versus $86 MSRP, and it still gives you a 2.0% average FPS lead across 50 shared CPU game tests in our data. Celeron P4505 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 2.0% in the shared gaming data.

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

Celeron P4505 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2006). That makes it the safer long-term bet.
