See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Atom E3825

2013

Why buy it

✅+4% higher PassMark.
✅Draws 6W instead of 89W, a 83W reduction.
✅100+% more PCIe lanes (4 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics (Bay Trail), while Opteron 146 needs a discrete GPU.

Trade-offs

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

Opteron 146

2003

Why buy it

Trade-offs

❌Lower PassMark (505 vs 525).
❌1383.3% higher power demand at 89W vs 6W.
❌No integrated graphics, while Atom E3825 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Atom E3825 better than Opteron 146?

Not really, because they are built for different jobs. Opteron 146 makes more sense for workstation-style multi-core throughput, while Atom E3825 is the more practical desktop choice for gaming, platform cost, and everyday use.

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

For streaming, content creation, and heavier multitasking, Atom E3825 is the stronger fit. You are getting 4% better PassMark, backed by 2 cores and 2 threads.

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

Atom E3825 still makes the most sense overall. Atom E3825 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 4% better PassMark.

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

Atom E3825 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2003) and more multi-core headroom with 2 cores / 2 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
