Quick Answers

So, is Core i5-4302Y better than Celeron 4305U?

Yes. Core i5-4302Y is the better all-around CPU here. It gives you a 2.5% average FPS lead across 26 shared CPU game tests in our data and 1.2% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i5-4302Y is the better pick. According to our tests, it delivers 2.5% more average FPS across 26 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Core i5-4302Y is the stronger fit. You are getting 1.2% better PassMark, backed by 2 cores and 4 threads. It also has the larger cache pool with 50% larger total L3 cache (3 MB vs 2 MB).

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

Core i5-4302Y is the easy recommendation for a fresh desktop build. Core i5-4302Y comes in at an unclear MSRP at unclear MSRP versus $107 MSRP, and it still gives you a 2.5% average FPS lead across 26 shared CPU game tests in our data. Celeron 4305U only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 2.5% in the shared gaming data.

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

Celeron 4305U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2013). That makes it the safer long-term bet.
