FX-8120 vs Xeon D-2123IT: Pros, Cons & Final Verdict

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

FX-8120

2011

Why buy it

  • Better for gaming: +8.2% higher average FPS across 49 shared CPU benchmark tests.

Trade-offs

  • Lower PassMark (6,594 vs 6,689).
  • Launch MSRP is still $205 MSRP, while Xeon D-2123IT mostly shows up through inconsistent older-market listings.
  • 108.3% higher power demand at 125W vs 60W.

Xeon D-2123IT

2018

Why buy it

  • +1.4% higher PassMark.
  • Draws 60W instead of 125W, a 65W reduction.

Trade-offs

  • Worse for gaming: lower average FPS than FX-8120 across 49 shared CPU benchmark tests.

Quick Answers

So, is Xeon D-2123IT better than FX-8120?
Not really, because they are built for different jobs. Xeon D-2123IT makes more sense for workstation-style multi-core throughput, while FX-8120 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, Xeon D-2123IT is the stronger fit. You are getting 1.4% better PassMark, backed by 4 cores and 8 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Xeon D-2123IT is still the much better call for a fresh build. Xeon D-2123IT comes in at an unclear MSRP at unclear MSRP versus $205 MSRP, and it still gives you 1.4% better PassMark. FX-8120 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2011 platform. Even with 100.0% better value on paper (32.2 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on AM3+.
Which one is more future-proof for 2026 and beyond?
Xeon D-2123IT makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2011) and more multi-core headroom with 4 cores / 8 threads instead of 8/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
