Athlon II X2 240

2009

Why buy it

Trade-offs

❌Worse for gaming: lower average FPS than A4-3400 across 50 shared CPU benchmark tests.
❌Lower PassMark (1,060 vs 1,066).
❌Launch MSRP is still $60 MSRP, while A4-3400 mostly shows up through inconsistent older-market listings.
❌No integrated graphics, while A4-3400 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is A4-3400 better than Athlon II X2 240?

Yes. A4-3400 is the better all-around CPU here. It gives you a 3.9% average FPS lead across 50 shared CPU game tests in our data, 0.6% 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, A4-3400 is the better pick. According to our tests, it delivers 3.9% 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, A4-3400 is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 2 threads.

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

A4-3400 is still the much better call for a fresh build. A4-3400 comes in at an unclear MSRP at unclear MSRP versus $60 MSRP, and it still gives you a 3.9% average FPS lead across 50 shared CPU game tests in our data. Athlon II X2 240 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 100.0% better value on paper (17.7 vs 0.0 PassMark/$), 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?

A4-3400 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2009) and 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.
