Quick Answers

So, is Pentium D 820 better than Celeron 1020E?

Yes. Pentium D 820 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 0.4% 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 820 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 820 is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 2 threads.

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

Pentium D 820 is still the much better call for a fresh build. Pentium D 820 comes in 180.2% more expensive on MSRP at $241 MSRP versus $86 MSRP, and it still gives you a 2.0% average FPS lead across 50 shared CPU game tests in our data. Celeron 1020E only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2013 platform. Even with 179.0% better value on paper (16.3 vs 5.9 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on G2.

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

Celeron 1020E makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2005). That makes it the safer long-term bet.
