Core i5-10400F vs Xeon D-1823NT: Pros, Cons & Final Verdict

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

Core i5-10400F

2020

Why buy it

  • Better for gaming: +17.1% higher average FPS across 50 shared CPU benchmark tests.
  • +20% larger total L3 cache (12 MB vs 10 MB).
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Includes a boxed cooler (Yes), unlike Xeon D-1823NT.

Trade-offs

  • Lower PassMark (13,029 vs 13,673).
  • Launch MSRP is still $160 MSRP, while Xeon D-1823NT mostly shows up through inconsistent older-market listings.
  • 18.2% higher power demand at 65W vs 55W.

Xeon D-1823NT

2023

Why buy it

  • +4.9% higher PassMark.
  • Draws 55W instead of 65W, a 10W reduction.

Trade-offs

  • Worse for gaming: lower average FPS than Core i5-10400F across 50 shared CPU benchmark tests.
  • Smaller total L3 cache (10 MB vs 12 MB).
  • No boxed cooler included, unlike Core i5-10400F.

Quick Answers

So, is Xeon D-1823NT better than Core i5-10400F?
Not really, because they are built for different jobs. Xeon D-1823NT makes more sense for workstation-style multi-core throughput, while Core i5-10400F 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-1823NT is the stronger fit. You are getting 4.9% better PassMark, backed by 6 cores and 12 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Xeon D-1823NT is still the faster CPU overall, but Core i5-10400F is easier to justify if budget matters more than peak performance. Xeon D-1823NT comes in at an unclear MSRP at unclear MSRP versus $160 MSRP, and it still gives you 4.9% better PassMark. The compromise is that Core i5-10400F is still the better pure gaming CPU with a 17.1% average FPS lead across 50 shared CPU game tests in our data. Core i5-10400F is also 100.0% better value on MSRP (81.4 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.
Which one is more future-proof for 2026 and beyond?
Xeon D-1823NT makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2020) and more multi-core headroom with 6 cores / 12 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
