Quick Answers

So, is Pentium D 940 better than Pentium Dual-Core E2140?

Yes. Pentium D 940 is the better all-around CPU here. It gives you a 9.9% average FPS lead across 50 shared CPU game tests in our data and 7.4% 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 940 is the better pick. According to our tests, it delivers 9.9% 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 7.4% 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 still the much better call for a fresh build. Pentium D 940 comes in 78.4% more expensive on MSRP at $132 MSRP versus $74 MSRP, and it still gives you a 9.9% average FPS lead across 50 shared CPU game tests in our data. Pentium Dual-Core E2140 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2007 platform. Even with 66.1% better value on paper (11.0 vs 6.6 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA775.

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

Pentium Dual-Core E2140 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2007 vs 2006). That makes it the safer long-term bet.
