Quick Answers

So, is Opteron 154 better than Celeron U3600?

Not really, because they are built for different jobs. Opteron 154 makes more sense for workstation-style multi-core throughput, while Celeron U3600 is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for gaming?

If gaming is the priority, Opteron 154 has the edge because it leads the single-thread side of this matchup with 2700% higher max boost clock.

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

For streaming, content creation, and heavier multitasking, Opteron 154 is the stronger fit. You are getting 4.8% better PassMark, backed by 1 cores and 1 threads.

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

Opteron 154 is the easy recommendation for a fresh desktop build. Opteron 154 comes in at an unclear MSRP at unclear MSRP versus $134 MSRP, and it still gives you 4.8% higher PassMark. Celeron U3600 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games.

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

Celeron U3600 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2005). That makes it the safer long-term bet.
