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 2.8% average FPS lead across 49 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 $86 MSRP versus unclear MSRP, and it still gives you a 2.8% average FPS lead across 49 shared CPU game tests in our data. The compromise is that Core i5-6287U is still stronger for heavier multi-core work with 1.1% better PassMark. It is also 100.0% better value on MSRP (43.7 vs 0.0 PassMark/$), 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.
