Benchmarking the Celeron 2955U

I recently purchased an HP Chromebook 14 (HP Falco) with a new Haswell(ish) Celeron 2955U. Arguably, the internals of a Chrome OS laptop are less important but I was still curious about just how fast the Celeron 2955U could be. At this point I cannot find a lot of data, so I decided to run a quick test in benchmarking the Celeron 2955U. To do this, I relied on two quick tools – nbench and geekbench. To run these two, I relied on a CLI-only install of Ubuntu 12.04 via crouton.

With that said, the real question is – just how did the Celeron 2955U perform?

Geekbench results

I used the latest version of Geekbench (3.1.2) for this test and ran in 32-bit mode.

=> Overall Performance Single-Core Score - 1350 Multi-Core Score - 2401 => Integer Performance Single-core - 1115 Multi-core - 2219 => Floating Point Performance Single-core - 1248 Multi-core - 2482

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.

For comparison, my G7 HP MicroServer with a Turion(tm) II Neo N54L had the following scores:

Next steps

In the coming days I am going to run a few more (actually useful) tests to see what the hardware in the laptop can do.
