Quick Answers

So, is Pentium E6600 better than Pentium E5800?

It depends on what you want from the system. For gaming, Pentium E5800 is ahead with 4471.4% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Pentium E6600 pulls ahead with 0.3% better PassMark.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Pentium E6600 is the stronger fit. You are getting 0.3% better PassMark, backed by 2 cores and 2 threads.

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

Pentium E6600 is still the much better call for a fresh build. Pentium E6600 comes in 31.3% more expensive on MSRP at $84 MSRP versus $64 MSRP, and it still gives you 0.3% better PassMark. Pentium E5800 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 30.8% better value on paper (18.6 vs 14.2 PassMark/$), 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?

Pentium E6600 makes more sense long term for 2026 and beyond. You are getting 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.
