Quick Answers

So, is A6 PRO-7400B better than Atom N570?

Yes. A6 PRO-7400B is the better all-around CPU here. It gives you a 0.6% average FPS lead across 50 shared CPU game tests in our data, 0.6% 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, A6 PRO-7400B is the better pick. According to our tests, it delivers 0.6% 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, A6 PRO-7400B is the stronger fit. You are getting 0.6% better PassMark, backed by 2 cores and 2 threads.

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

A6 PRO-7400B still makes the most sense overall. A6 PRO-7400B comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 0.6% average FPS lead across 50 shared CPU game tests in our data.

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

A6 PRO-7400B makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2011) 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.
