Quick Answers

So, is Core Duo T2050 better than Athlon II Neo K145?

Yes. Core Duo T2050 is the better all-around CPU here. It gives you a 7.1% average FPS lead across 48 shared CPU game tests in our data and 3.5% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core Duo T2050 is the better pick. According to our tests, it delivers 7.1% more average FPS across 48 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Core Duo T2050 is the stronger fit. You are getting 3.5% better PassMark, backed by 2 cores and 2 threads.

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

Core Duo T2050 is still the much better call for a fresh build. Core Duo T2050 comes in at an unclear MSRP at unclear MSRP versus $50 MSRP, and it still gives you a 7.1% average FPS lead across 48 shared CPU game tests in our data. Athlon II Neo K145 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 100.0% better value on paper (11.3 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on S1.

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

Athlon II Neo K145 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2005). That makes it the safer long-term bet.
