Quick Answers

So, is Celeron 5305U better than A4-5100?

Yes. Celeron 5305U is the better all-around CPU here. It gives you a 2.0% average FPS lead across 50 shared CPU game tests in our data, 0.5% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Celeron 5305U is the better pick. According to our tests, it delivers 2.0% more average FPS across 50 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Celeron 5305U 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 5305U still makes the most sense overall. Celeron 5305U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 2.0% average FPS lead across 50 shared CPU game tests in our data.

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

Celeron 5305U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2013) and more multi-core headroom with 2 cores / 2 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
