Core Ultra 5 134U vs Xeon E5-1680 v3: Pros, Cons & Final Verdict

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

Core Ultra 5 134U

2023

Why buy it

  • Newer platform on FCBGA2551 with DDR5 support instead of LGA2011 and DDR4.

Trade-offs

  • Lower PassMark (13,169 vs 13,273).
  • Smaller total L3 cache (12 MB vs 20 MB).
  • Less compelling for workstation-style loads than Xeon E5-1680 v3, which brings 8 cores / 16 threads and 40 PCIe lanes.

Xeon E5-1680 v3

2014

Why buy it

  • +0.8% higher PassMark.
  • +66.7% larger total L3 cache (20 MB vs 12 MB).
  • Better for workstations and heavier parallel workloads: 8 cores / 16 threads, plus 40 PCIe lanes vs 0.
  • 100+% more PCIe lanes (40 vs 0) for storage and expansion-heavy builds.

Trade-offs

  • Launch MSRP is still $1,723 MSRP, while Core Ultra 5 134U mostly shows up through inconsistent older-market listings.
  • Older platform position on LGA2011 with DDR4, while Core Ultra 5 134U moves to FCBGA2551 and DDR5.

Quick Answers

So, is Xeon E5-1680 v3 better than Core Ultra 5 134U?
Not really, because they are built for different jobs. Xeon E5-1680 v3 makes more sense for workstation-style multi-core throughput, while Core Ultra 5 134U 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 E5-1680 v3 is the stronger fit. You are getting 0.8% better PassMark, backed by 8 cores and 16 threads. It also has the larger cache pool with 66.7% larger total L3 cache (20 MB vs 12 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Xeon E5-1680 v3 is the better buy right now. Xeon E5-1680 v3 comes in at an unclear MSRP at $1,723 MSRP versus unclear MSRP, and it still gives you 0.8% better PassMark. The compromise is that Core Ultra 5 134U is still the better pure gaming CPU with a 0.8% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (7.7 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
Which one is more future-proof for 2026 and beyond?
Core Ultra 5 134U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2023 vs 2014) and a healthier platform with FCBGA2551 and DDR5 instead of LGA2011. That gives you a healthier platform runway for motherboard, RAM, and later CPU upgrades.
