Quick Answers

So, is Core i5-2405S better than Core i7-880?

It depends on what you want from the system. For gaming, Core i7-880 is ahead with a 10.8% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-2405S pulls ahead with 0.1% better Geekbench multi-core. Core i7-880 also has the bigger cache pool with 33.3% larger total L3 cache (8 MB vs 6 MB).

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

For streaming, content creation, and heavier multitasking, Core i5-2405S is the stronger fit. You are getting 0.1% better Geekbench multi-core, backed by 4 cores and 4 threads.

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

Core i5-2405S is the better buy right now. Core i5-2405S comes in $274 cheaper on MSRP at $309 MSRP versus $583 MSRP, and it still gives you 0.1% better Geekbench multi-core. The compromise is that Core i7-880 is still the better pure gaming CPU with a 10.8% average FPS lead across 50 shared CPU game tests in our data. It is also 86.9% better value on MSRP (11.0 vs 5.9 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Core i5-2405S 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 4 cores / 4 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
