  • Includes a boxed cooler (Yes), unlike Core i3-6102E.

Trade-offs

  • 300% higher power demand at 100W vs 25W.

Core i3-6102E

2015

Why buy it

  • Draws 25W instead of 100W, a 75W reduction.

Trade-offs

  • Lower PassMark (2,349 vs 2,360).
  • Launch MSRP is still $225 MSRP, while A8-3870K mostly shows up through inconsistent older-market listings.
  • No boxed cooler included, unlike A8-3870K.

Quick Answers

So, is A8-3870K better than Core i3-6102E?
Yes. A8-3870K is the better all-around CPU here. It gives you a 2.3% average FPS lead across 50 shared CPU game tests in our data and 0.5% better PassMark, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, A8-3870K is the better pick. According to our tests, it delivers 2.3% 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, A8-3870K is the stronger fit. You are getting 0.5% better PassMark, backed by 4 cores and 4 threads.
Which one is the smarter buy today, not just the cheaper CPU?
A8-3870K is still the much better call for a fresh build. A8-3870K comes in at an unclear MSRP at unclear MSRP versus $225 MSRP, and it still gives you a 2.3% average FPS lead across 50 shared CPU game tests in our data. Core i3-6102E only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2015 platform. Even with 100.0% better value on paper (10.4 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on that older DDR4-era platform.
Which one is more future-proof for 2026 and beyond?
Core i3-6102E makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2011). That makes it the safer long-term bet.
