❌111.1% higher power demand at 95W vs 45W.

Xeon D-1520

2015

Why buy it

✅+1.2% higher PassMark.
✅Draws 45W instead of 95W, a 50W reduction.

Trade-offs

❌Smaller total L3 cache (1.5 MB vs 8 MB).

Quick Answers

So, is Xeon D-1520 better than FX-8140?

Not really, because they are built for different jobs. Xeon D-1520 makes more sense for workstation-style multi-core throughput, while FX-8140 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-1520 is the stronger fit. You are getting 1.2% better PassMark, backed by 4 cores and 8 threads.

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

Xeon D-1520 is still the much better call for a fresh build. Xeon D-1520 comes in at an unclear MSRP at unclear MSRP versus $225 MSRP, and it still gives you 1.2% better PassMark. FX-8140 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2012 platform. Even with 100.0% better value on paper (21.6 vs 0.0 PassMark/$), 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-1520 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2012) 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.
