Core i7-4790T vs Xeon E3-1275L 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 i7-4790T

2014

Why buy it

  • Better for gaming: +6.0% higher average FPS across 50 shared CPU benchmark tests.
  • Costs $47 less on MSRP ($303 MSRP vs $350 MSRP).
  • Delivers 15.5% more PassMark for each dollar spent, at 20.9 vs 18.1 PassMark/$ ($303 MSRP vs $350 MSRP).

Trade-offs

  • Lower PassMark (6,325 vs 6,327).
  • Less compelling for workstation-style loads than Xeon E3-1275L v3, which brings 4 cores / 8 threads and 16 PCIe lanes.
  • No integrated graphics, while Xeon E3-1275L v3 can still boot and troubleshoot without a discrete GPU.

Xeon E3-1275L v3

2014

Why buy it

  • +0% higher PassMark.
  • Better for workstations and heavier parallel workloads: 4 cores / 8 threads, plus 16 PCIe lanes vs 0.
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with Intel HD Graphics P4600, while Core i7-4790T needs a discrete GPU.

Trade-offs

  • Worse for gaming: lower average FPS than Core i7-4790T across 50 shared CPU benchmark tests.
  • Lower PassMark per dollar, at 18.1 vs 20.9 PassMark/$ ($350 MSRP vs $303 MSRP).

Quick Answers

So, is Xeon E3-1275L v3 better than Core i7-4790T?
Not really, because they are built for different jobs. Xeon E3-1275L v3 makes more sense for workstation-style multi-core throughput, while Core i7-4790T 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 E3-1275L v3 is the stronger fit. You are getting 0% better PassMark, backed by 4 cores and 8 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Xeon E3-1275L v3 is still the much better call for a fresh build. Xeon E3-1275L v3 comes in 15.5% more expensive on MSRP at $350 MSRP versus $303 MSRP, and it still gives you 0% better PassMark. Core i7-4790T only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2014 platform. Even with 15.5% better value on paper (20.9 vs 18.1 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1150.
Which one is more future-proof for 2026 and beyond?
Xeon E3-1275L v3 makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 4 cores / 8 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
