Quick Answers

So, is Core i5-2510E better than Pentium G2120?
Yes. Core i5-2510E is the better all-around CPU here. It gives you a 1.7% average FPS lead across 20 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?
For gaming, this matchup is basically a tie in the data we have.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i5-2510E is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 4 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i5-2510E is still the much better call for a fresh build. Core i5-2510E comes in 167.4% more expensive on MSRP at $230 MSRP versus $86 MSRP, and it still gives you a 1.7% average FPS lead across 20 shared CPU game tests in our data. Pentium G2120 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 166.3% better value on paper (21.8 vs 8.2 PassMark/$), 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 G2120 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2012 vs 2011). That makes it the safer long-term bet.
