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

Atom E3845

2013

Why buy it

✅Draws 10W instead of 18W, a 8W reduction.
✅100+% more PCIe lanes (4 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel HD Graphics (Bay Trail), while E-450 needs a discrete GPU.

Trade-offs

❌Fewer obvious downsides in this matchup outside of normal market pricing swings.

E-450

2011

Why buy it

Trade-offs

❌Lower PassMark (1,063 vs 1,071).
❌80% higher power demand at 18W vs 10W.
❌No integrated graphics, while Atom E3845 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Atom E3845 better than E-450?

Yes. Atom E3845 is the better all-around CPU here. It gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data, 0.8% 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, Atom E3845 is the better pick. According to our tests, it delivers 0.1% 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, Atom E3845 is the stronger fit. You are getting 0.8% better PassMark, backed by 4 cores and 4 threads.

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

Atom E3845 still makes the most sense overall. Atom E3845 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 0.1% average FPS lead across 50 shared CPU game tests in our data.

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

Atom E3845 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2011) and more multi-core headroom with 4 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
