Quick Answers

So, is Celeron 847 better than Core i5-450M?

It depends on what you want from the system. For gaming, Core i5-450M is ahead with a 0.1% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron 847 pulls ahead with 0.5% better PassMark. Core i5-450M also has the bigger cache pool with 50% larger total L3 cache (3 MB vs 2 MB).

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

For streaming, content creation, and heavier multitasking, Celeron 847 is the stronger fit. You are getting 0.5% better PassMark, backed by 2 cores and 2 threads.

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

Celeron 847 is still the much better call for a fresh build. Celeron 847 comes in 318.8% more expensive on MSRP at $134 MSRP versus $32 MSRP, and it still gives you 0.5% better PassMark. Core i5-450M only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2010 platform. Even with 316.8% better value on paper (39.5 vs 9.5 PassMark/$), 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 847 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2010) and more multi-core headroom with 2 cores / 2 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
