Core i5-6287U vs Pentium G4620: Pros, Cons & Final Verdict

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

Core i5-6287U

2015

Why buy it

  • +1.1% higher PassMark.
  • +33.3% larger total L3 cache (4 MB vs 3 MB).
  • Draws 28W instead of 51W, a 23W reduction.
  • 100+% more PCIe lanes (12 vs 0) for storage and expansion-heavy builds.
  • Integrated graphics onboard with Iris Graphics 550, while Pentium G4620 needs a discrete GPU.

Trade-offs

  • Worse for gaming: lower average FPS than Pentium G4620 across 50 shared CPU benchmark tests.

Pentium G4620

2017

Why buy it

  • Better for gaming: +3.0% higher average FPS across 50 shared CPU benchmark tests.

Trade-offs

  • Lower PassMark (3,761 vs 3,801).
  • Smaller total L3 cache (3 MB vs 4 MB).
  • Launch MSRP is still $86 MSRP, while Core i5-6287U mostly shows up through inconsistent older-market listings.
  • 82.1% higher power demand at 51W vs 28W.
  • No integrated graphics, while Core i5-6287U can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Pentium G4620 better than Core i5-6287U?
It depends on what you want from the system. For gaming, Pentium G4620 is ahead with a 3.0% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-6287U pulls ahead with 1.1% better PassMark. Core i5-6287U also has the bigger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i5-6287U is the stronger fit. You are getting 1.1% better PassMark, backed by 2 cores and 4 threads. It also has the larger cache pool with 33.3% larger total L3 cache (4 MB vs 3 MB).
Which one is the smarter buy today, not just the cheaper CPU?
Pentium G4620 is the better buy right now. Pentium G4620 comes in at an unclear MSRP at $86 MSRP versus unclear MSRP, and it still gives you a 3.0% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i5-6287U is still stronger for heavier multi-core work with 1.1% better PassMark. It is also 100.0% better value on MSRP (43.7 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
Which one is more future-proof for 2026 and beyond?
Pentium G4620 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2015). That makes it the safer long-term bet.
