Quick Answers

So, is Core 2 Duo E8135 better than Pentium J2850?

Yes. Core 2 Duo E8135 is the better all-around CPU here. It gives you a 5.5% average FPS lead across 50 shared CPU game tests in our data and 0.4% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core 2 Duo E8135 is the better pick. According to our tests, it delivers 5.5% 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 2 Duo E8135 is the stronger fit. You are getting 0.4% better PassMark, backed by 2 cores and 2 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Core 2 Duo E8135 is the easy recommendation for a fresh desktop build. Core 2 Duo E8135 comes in 112.8% more expensive on MSRP at $200 MSRP versus $94 MSRP, and it still gives you a 5.5% average FPS lead across 50 shared CPU game tests in our data. Pentium J2850 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 5.5% in the shared gaming data.

Which one is more future-proof for 2026 and beyond?

Pentium J2850 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2009). That makes it the safer long-term bet.
