See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

A6-5400B

2012

Why buy it

✅100+% more PCIe lanes (16 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Radeon HD 7540D, while Celeron N4000 needs a discrete GPU.
✅Includes a boxed cooler (Yes), unlike Celeron N4000.

Trade-offs

❌Lower PassMark (1,465 vs 1,472).
❌983.3% higher power demand at 65W vs 6W.

Celeron N4000

2017

Why buy it

✅+0.5% higher PassMark.
✅Draws 6W instead of 65W, a 59W reduction.

Trade-offs

❌Launch MSRP is still $107 MSRP, while A6-5400B mostly shows up through inconsistent older-market listings.
❌No integrated graphics, while A6-5400B can still boot and troubleshoot without a discrete GPU.
❌No boxed cooler included, unlike A6-5400B.

Quick Answers

So, is Celeron N4000 better than A6-5400B?

It depends on what you want from the system. For gaming, A6-5400B is ahead with a 2.8% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron N4000 pulls ahead with 0.5% better PassMark.

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

For streaming, content creation, and heavier multitasking, Celeron N4000 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 N4000 is the better buy right now. Celeron N4000 comes in at an unclear MSRP at $107 MSRP versus unclear MSRP, and it still gives you 0.5% better PassMark. The compromise is that A6-5400B is still the better pure gaming CPU with a 2.8% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (13.8 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Celeron N4000 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2012) and more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
