Quick Answers

So, is Pentium N3520 better than Pentium G640T?

Yes. Pentium N3520 is the better all-around CPU here. It gives you a 3.4% average FPS lead across 44 shared CPU game tests in our data, 0.4% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Pentium N3520 is the better pick. According to our tests, it delivers 3.4% more average FPS across 44 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Pentium N3520 is the stronger fit. You are getting 0.4% better PassMark, backed by 4 cores and 4 threads.

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

Pentium N3520 is still the much better call for a fresh build. Pentium N3520 comes in 56.3% more expensive on MSRP at $100 MSRP versus $64 MSRP, and it still gives you a 3.4% average FPS lead across 44 shared CPU game tests in our data. Pentium G640T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 55.6% better value on paper (17.8 vs 11.4 PassMark/$), 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 N3520 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2012) and more multi-core headroom with 4 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
