Quick Answers

So, is Athlon II X2 250e better than Athlon II Neo K345?
Yes. Athlon II X2 250e is the better all-around CPU here. It gives you 0.9% 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, Athlon II X2 250e has the edge because it leads the single-thread side of this matchup with 114.3% higher max boost clock.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Athlon II X2 250e is the stronger fit. You are getting 0.9% better PassMark, backed by 2 cores and 2 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Athlon II X2 250e is still the much better call for a fresh build. Athlon II X2 250e comes in 54.0% more expensive on MSRP at $77 MSRP versus $50 MSRP, and it still gives you 0.9% higher PassMark. Athlon II Neo K345 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 52.6% better value on paper (23.8 vs 15.6 PassMark/$), 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 X2 250e makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
