Quick Answers

So, is Phenom II X6 1065T better than Core i5-2405S?

Yes. Phenom II X6 1065T is the better all-around CPU here. It gives you a 1.9% average FPS lead across 50 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?

If gaming is the priority, Phenom II X6 1065T is the better pick. According to our tests, it delivers 1.9% 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, Phenom II X6 1065T is the stronger fit. You are getting 0.4% better PassMark, backed by 6 cores and 6 threads.

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

Phenom II X6 1065T is still the much better call for a fresh build. Phenom II X6 1065T comes in 37.9% more expensive on MSRP at $426 MSRP versus $309 MSRP, and it still gives you a 1.9% average FPS lead across 50 shared CPU game tests in our data. Core i5-2405S only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2011 platform. Even with 37.3% better value on paper (11.0 vs 8.0 PassMark/$), 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?

Core i5-2405S makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2010). That makes it the safer long-term bet.
