Core i5-5575R vs Xeon E3-1235: Pros, Cons & Final Verdict

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

Core i5-5575R

2015

Why buy it

  • Draws 65W instead of 95W, a 30W reduction.
  • 100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with Iris Pro Graphics 6200, while Xeon E3-1235 needs a discrete GPU.

Trade-offs

  • Worse for gaming: lower average FPS than Xeon E3-1235 across 50 shared CPU benchmark tests.
  • Lower PassMark (5,074 vs 5,112).
  • Smaller total L3 cache (4 MB vs 8 MB).
  • Less compelling for workstation-style loads than Xeon E3-1235, which brings 4 cores / 8 threads.
  • Lower PassMark per dollar, at 19.1 vs 21.3 PassMark/$ ($265 MSRP vs $240 MSRP).

Xeon E3-1235

2011

Why buy it

  • Better for gaming: +8.9% higher average FPS across 50 shared CPU benchmark tests.
  • +100% larger total L3 cache (8 MB vs 4 MB).
  • Better for workstations and heavier parallel workloads: 4 cores / 8 threads.
  • Costs $25 less on MSRP ($240 MSRP vs $265 MSRP).
  • Delivers 11.2% more PassMark for each dollar spent, at 21.3 vs 19.1 PassMark/$ ($240 MSRP vs $265 MSRP).

Trade-offs

  • 46.2% higher power demand at 95W vs 65W.
  • No integrated graphics, while Core i5-5575R can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Xeon E3-1235 better than Core i5-5575R?
Not really, because they are built for different jobs. Xeon E3-1235 makes more sense for workstation-style multi-core throughput, while Core i5-5575R is the more practical desktop choice for gaming, platform cost, and everyday use.
Which one is better for gaming?
