Core i3-1125G4 vs Xeon E5-2620 v4: Pros, Cons & Final Verdict

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

Core i3-1125G4

2021

Why buy it

  • +0.3% higher PassMark.
  • Draws 15W instead of 85W, a 70W reduction.
  • Integrated graphics onboard with UHD Graphics (48 EU), while Xeon E5-2620 v4 needs a discrete GPU.

Trade-offs

  • Worse for gaming: lower average FPS than Xeon E5-2620 v4 across 50 shared CPU benchmark tests.
  • Smaller total L3 cache (8 MB vs 20 MB).
  • Less compelling for workstation-style loads than Xeon E5-2620 v4, which brings 8 cores / 16 threads and 40 PCIe lanes.

Xeon E5-2620 v4

2016

Why buy it

  • Better for gaming: +18.8% higher average FPS across 50 shared CPU benchmark tests.
  • +150% larger total L3 cache (20 MB vs 8 MB).
  • Better for workstations and heavier parallel workloads: 8 cores / 16 threads, plus 40 PCIe lanes vs 16.
  • 150% more PCIe lanes (40 vs 16) for storage and expansion-heavy builds.

Trade-offs

  • Lower PassMark (9,255 vs 9,284).
  • Launch MSRP is still $417 MSRP, while Core i3-1125G4 mostly shows up through inconsistent older-market listings.
  • 466.7% higher power demand at 85W vs 15W.
  • No integrated graphics, while Core i3-1125G4 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Core i3-1125G4 better than Xeon E5-2620 v4?
Not really, because they are built for different jobs. Xeon E5-2620 v4 makes more sense for workstation-style multi-core throughput, while Core i3-1125G4 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, Core i3-1125G4 is the stronger fit. You are getting 0.3% better PassMark, backed by 4 cores and 8 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i3-1125G4 is still the faster CPU overall, but Xeon E5-2620 v4 is easier to justify if budget matters more than peak performance. Core i3-1125G4 comes in at an unclear MSRP at unclear MSRP versus $417 MSRP, and it still gives you 0.3% better PassMark. The compromise is that Xeon E5-2620 v4 is still the better pure gaming CPU with a 18.8% average FPS lead across 50 shared CPU game tests in our data. Xeon E5-2620 v4 is also 100.0% better value on MSRP (22.2 vs 0.0 PassMark/$), which is why it can still make sense for tighter-budget builds on paper.
Which one is more future-proof for 2026 and beyond?
Core i3-1125G4 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2021 vs 2016), more multi-core headroom with 4 cores / 8 threads instead of 8/16, and AVX-512 support for heavier modern compute workloads. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
