Core i7-5775R vs Xeon E5-2450: Pros, Cons & Final Verdict

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

Core i7-5775R

2015

Why buy it

  • Draws 65W instead of 95W, a 30W reduction.

Trade-offs

  • Smaller total L3 cache (6 MB vs 20 MB).
  • Less compelling for workstation-style loads than Xeon E5-2450, which brings 8 cores / 16 threads.

Xeon E5-2450

2012

Why buy it

  • +233.3% larger total L3 cache (20 MB vs 6 MB).
  • Better for workstations and heavier parallel workloads: 8 cores / 16 threads.

Trade-offs

  • Lower PassMark (7,534 vs 7,598).
  • Launch MSRP is still $694 MSRP, while Core i7-5775R mostly shows up through inconsistent older-market listings.
  • 46.2% higher power demand at 95W vs 65W.

Quick Answers

So, is Core i7-5775R better than Xeon E5-2450?
Not really, because they are built for different jobs. Xeon E5-2450 makes more sense for workstation-style multi-core throughput, while Core i7-5775R is the more practical desktop choice for gaming, platform cost, and everyday use.
Which one is better for gaming?
If gaming is the priority, Core i7-5775R is the better pick. According to our tests, it delivers 1.0% more average FPS across 50 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i7-5775R is the stronger fit. You are getting 0.8% better PassMark, backed by 4 cores and 8 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i7-5775R is still the faster CPU overall, but Xeon E5-2450 is easier to justify if budget matters more than peak performance. Core i7-5775R comes in at an unclear MSRP at unclear MSRP versus $694 MSRP, and it still gives you a 1.0% average FPS lead across 50 shared CPU game tests in our data. Xeon E5-2450 is also 100.0% better value on MSRP (10.9 vs 0.0 PassMark/$), 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 i7-5775R makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2012) and more multi-core headroom with 4 cores / 8 threads instead of 8/16. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
