Quick Answers

So, is Core 2 Duo E6540 better than Pentium G850?

Yes. Core 2 Duo E6540 is the better all-around CPU here. It gives you a 3.0% average FPS lead across 49 shared CPU game tests in our data and 0.3% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core 2 Duo E6540 is the better pick. According to our tests, it delivers 3.0% more average FPS across 49 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Core 2 Duo E6540 is the stronger fit. You are getting 0.3% better PassMark. It also has the larger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).

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

Core 2 Duo E6540 is still the much better call for a fresh build. Core 2 Duo E6540 comes in 89.5% more expensive on MSRP at $163 MSRP versus $86 MSRP, and it still gives you a 3.0% average FPS lead across 49 shared CPU game tests in our data. Pentium G850 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2011 platform. Even with 89.0% better value on paper (17.3 vs 9.2 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1155.

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

Pentium G850 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2007). That makes it the safer long-term bet.
