Quick Answers

So, is Core 2 Extreme X7800 better than Celeron 1005M?

Yes. Core 2 Extreme X7800 is the better all-around CPU here. It gives you 2% 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 Extreme X7800 has the edge because it leads the single-thread side of this matchup with 36.8% higher max boost clock.

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

For streaming, content creation, and heavier multitasking, Core 2 Extreme X7800 is the stronger fit. You are getting 2% better PassMark, backed by 2 cores and 2 threads. It also has the larger cache pool with 100% larger total L3 cache (4 MB vs 2 MB).

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

Core 2 Extreme X7800 is still the much better call for a fresh build. Core 2 Extreme X7800 comes in at an unclear MSRP at unclear MSRP versus $86 MSRP, and it still gives you 2.0% higher PassMark. Celeron 1005M only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2013 platform. Even with 100.0% better value on paper (13.0 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA988.

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

Celeron 1005M makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2007). That makes it the safer long-term bet.
