Quick Answers

So, is Core 2 Duo E8300 better than Athlon II X2 270u?

Yes. Core 2 Duo E8300 is the better all-around CPU here. It gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data and 88.3% better Cinebench R23 multi-core, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core 2 Duo E8300 is the better pick. According to our tests, it delivers 0.2% 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, Core 2 Duo E8300 is the stronger fit. You are getting 88.3% better Cinebench R23 multi-core, backed by 2 cores and 2 threads.

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

Core 2 Duo E8300 is still the much better call for a fresh build. Core 2 Duo E8300 comes in 139.7% more expensive on MSRP at $163 MSRP versus $68 MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data. Athlon II X2 270u only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 141.1% better value on paper (15.4 vs 6.4 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on AM3.

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

Athlon II X2 270u makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2008). That makes it the safer long-term bet.
