Athlon X4 845

2016

Why buy it

✅100+% more PCIe lanes (8 vs 0) for storage and expansion-heavy builds.

Trade-offs

❌Worse for gaming: lower average FPS than Opteron 3280 across 50 shared CPU benchmark tests.
❌Lower PassMark (3,768 vs 3,783).
❌Less compelling for workstation-style loads than Opteron 3280, which brings 8 cores / 8 threads.
❌Launch MSRP is still $70 MSRP, while Opteron 3280 mostly shows up through inconsistent older-market listings.

Opteron 3280

2012

Why buy it

✅Better for gaming: +3.7% higher average FPS across 50 shared CPU benchmark tests.
✅Better for workstations and heavier parallel workloads: 8 cores / 8 threads.

Trade-offs

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

Quick Answers

So, is Opteron 3280 better than Athlon X4 845?

Not really, because they are built for different jobs. Opteron 3280 makes more sense for workstation-style multi-core throughput, while Athlon X4 845 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 3280 is the better pick. According to our tests, it delivers 3.7% 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, Opteron 3280 is the stronger fit. You are getting 0.4% better PassMark, backed by 8 cores and 8 threads.

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

Opteron 3280 is still the much better call for a fresh build. Opteron 3280 comes in at an unclear MSRP at unclear MSRP versus $70 MSRP, and it still gives you a 3.7% average FPS lead across 50 shared CPU game tests in our data. Athlon X4 845 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2016 platform. Even with 100.0% better value on paper (53.8 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on FM2+.

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

Athlon X4 845 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2016 vs 2012). That makes it the safer long-term bet.
