Quick Answers

So, is Celeron E1500 better than Celeron E1400?

Yes. Celeron E1500 is the better all-around CPU here. It gives you a 5.5% average FPS lead across 50 shared CPU game tests in our data, 9.6% better Geekbench multi-core, 7.0% higher 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 E1500 is the better pick. According to our tests, it delivers 5.5% 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 E1500 is the stronger fit. You are getting 9.6% better Geekbench multi-core, backed by 2 cores and 2 threads.

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

Celeron E1500 is the better buy right now. Celeron E1500 comes in in basically the same MSRP band at $53 MSRP versus $53 MSRP, and it still gives you a 5.5% average FPS lead across 50 shared CPU game tests in our data. It is also 7.0% better value on MSRP (14.4 vs 13.5 PassMark/$), 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 E1500 makes more sense long term for 2026 and beyond. You are getting 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.
