Trade-offs

❌Launch MSRP is still $49 MSRP, while Phenom II X3 P840 mostly shows up through inconsistent older-market listings.
❌2233.3% higher power demand at 35W vs 1.5W.

Phenom II X3 P840

2010

Why buy it

✅Draws 2W instead of 35W, a 34W reduction.

Trade-offs

❌Worse for gaming: lower average FPS than Athlon 3000G across 50 shared CPU benchmark tests.
❌Lower PassMark (4,425 vs 4,446).
❌No integrated graphics, while Athlon 3000G can still boot and troubleshoot without a discrete GPU.
❌No boxed cooler included, unlike Athlon 3000G.

Quick Answers

So, is Athlon 3000G better than Phenom II X3 P840?

Yes. Athlon 3000G is the better all-around CPU here. It gives you a 5.9% average FPS lead across 50 shared CPU game tests in our data, 0.5% 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 3000G is the better pick. According to our tests, it delivers 5.9% 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, Athlon 3000G is the stronger fit. You are getting 0.5% better PassMark, backed by 2 cores and 4 threads.

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

Athlon 3000G is the better buy right now. Athlon 3000G comes in at an unclear MSRP at $49 MSRP versus unclear MSRP, and it still gives you a 5.9% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (90.7 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Athlon 3000G makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2010) and more multi-core headroom with 2 cores / 4 threads instead of 3/3. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
