Quick Answers

So, is Pentium 4405Y better than Core i5-4300Y?

It depends on what you want from the system. For gaming, Core i5-4300Y is ahead with a 0.1% average FPS lead across 20 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Pentium 4405Y pulls ahead with 0.3% better PassMark. Core i5-4300Y 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, Pentium 4405Y is the stronger fit. You are getting 0.3% better PassMark, backed by 2 cores and 4 threads.

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

Pentium 4405Y still makes the most sense overall. Pentium 4405Y comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.3% better PassMark.

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

Pentium 4405Y makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2015 vs 2013) and more multi-core headroom with 2 cores / 4 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
