Quick Answers

So, is Core 2 Duo E8135 better than Core 2 Duo E4700?

Yes. Core 2 Duo E8135 is the better all-around CPU here. It gives you a 3.6% average FPS lead across 50 shared CPU game tests in our data, 0.9% better PassMark, and the stronger long-term platform, 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 3.6% 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 0.9% 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 still the much better call for a fresh build. Core 2 Duo E8135 comes in 50.4% more expensive on MSRP at $200 MSRP versus $133 MSRP, and it still gives you a 3.6% average FPS lead across 50 shared CPU game tests in our data. Core 2 Duo E4700 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 49.0% better value on paper (7.6 vs 5.1 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA775.

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

Core 2 Duo E8135 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2009 vs 2008) and more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
