A10-9620P

2017

Why buy it

✅Better for gaming: +6.3% higher average FPS across 50 shared CPU benchmark tests.
✅Draws 2W instead of 3W, a 1W reduction.
✅100+% more PCIe lanes (8 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Radeon R5, while Core 2 Duo P8400 needs a discrete GPU.

Trade-offs

❌Fewer obvious downsides in this matchup outside of normal market pricing swings.

Core 2 Duo P8400

2008

Why buy it

Trade-offs

❌Worse for gaming: lower average FPS than A10-9620P across 50 shared CPU benchmark tests.
❌Lower PassMark (2,497 vs 2,514).
❌Launch MSRP is still $209 MSRP, while A10-9620P mostly shows up through inconsistent older-market listings.
❌50% higher power demand at 3W vs 2W.
❌No integrated graphics, while A10-9620P can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is A10-9620P better than Core 2 Duo P8400?

Yes. A10-9620P is the better all-around CPU here. It gives you a 6.3% average FPS lead across 50 shared CPU game tests in our data, 0.7% 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, A10-9620P is the better pick. According to our tests, it delivers 6.3% 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, A10-9620P is the stronger fit. You are getting 0.7% better PassMark, backed by 4 cores and 4 threads.

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

A10-9620P is still the much better call for a fresh build. A10-9620P comes in at an unclear MSRP at unclear MSRP versus $209 MSRP, and it still gives you a 6.3% average FPS lead across 50 shared CPU game tests in our data. Core 2 Duo P8400 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 100.0% better value on paper (11.9 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA478.

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

A10-9620P makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2008) and more multi-core headroom with 4 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
