Benchmarks for Celeron N2830

I recently started tinkering with an Acer Chromebook 11 as a cheap computer to beat up and throw in my bag when I explore new places. While I have benchmarked the performance of the Chromebook in Chrome OS, I was curious how the CPU itself performs. This is especially interesting to me, as I have also benchmarked the Celeron 2955U found in other Chromebooks. To do this, I relied on two quick tools – nbench and geekbench. To run these two, I relied on a CLI-only install of Debian 7.7.0 via crouton.

With all of this in mind, just how did the Celeron N2830 perform and how does it stack up against the Celeron 2955U?

Geekbench results

I used the latest version of Geekbench (3.2.2) for this test and ran in 32-bit mode.

<br></br>  
=> Overall Performance<br></br>
Single-Core Score -   871<br></br>  
Multi-Core Score  -   1500```

=> Integer Performance  
 Single-core - 970  
 Multi-core - 1899

=> Floating Point Performance  
 Single-core - 693  
 Multi-core - 1372


## nbench results

Here’s the raw results from my nbench trial. I ran a few and all results were pretty close (+/- 1%) to this with and without the laptop plugged in.

Compared to the Celeron 2955U

The Celeron N2830 is a low-power and fanless SoC. While the benefit is potentially a long run time, a small profile, and no noise, you do trade off some performance. These tests indicate the N2830 is a bit slower than the 2955U. If you are in the market for a Chromebook, you will need to make the tradeoff here to find out the right mix of performance, profile, and price.
