Raspberry Pi 2 hands-on: Is the souped-up board ready to take on the PC?

Email and cloud storage
Raspberry Pi 2 – Model B
With hundreds of millions of users, Gmail is one of the world’s most widely used web-based email clients, so how does it run on the Pi 2?
Gmail defaults to its basic HTML view that requires the page to be reloaded more often and is missing features such as chat, yet is perfectly usable. It’s reasonably snappy, with the site taking about five seconds to load initially and about three seconds subsequently.
Google Drive also reverts to a simpler view, which again works absolutely fine. It took about 30 seconds to upload a 1.7MB file over a 10 megabit connection.
Although Google Drive did lock-up once during one attempted upload, the rest of the time both Gmail and Google Drive worked without any lag.
Raspberry Pi 1 – Model B
Gmail takes longer to load, about seven seconds initially and just over three seconds subsequently, but remains usable if you’re willing to wait a few seconds to view each message.
Google Drive took far longer to get going, more than 15 seconds, and suffered considerable lag when scrolling. More problematically the browser locked up and became unusable when trying to download and upload a file, as again the CPU maxed out.
Office suite
Office suite
Raspberry Pi 2 – Model B
The fact that a $35 machine can be used to run a free office suite is impressive.
The latest version of the open-source LibreOffice runs well, with Writer booting within 16 seconds initially, but opening almost instantly subsequently.
The application didn’t bog down when handling larger files, opening this this multi-page document containing several forms took just over a couple of seconds, 2.3.
Similarly the machine handles large spreadsheets with relative ease, with LibreOffice Calc fetching this Excel table with more than 32,400 rows in about three seconds.
Browsing documents online also means viewing PDFs, and the operating systems’ built-in PDF viewer also coped well, opening this paper within 3.5 seconds.
Scrolling through all three documents was smooth, apart from when scrolling to full-page images in the PDF, which triggered a 3.5 second delay.
Raspberry Pi 1- Model B
Again there was a pronounced difference in performance to the point where I found Libre Office to be unsuitable for certain tasks, with the suite taking more than 40 seconds to start Writer for the first time.
The document above took considerably longer to load, about 25 seconds, and suffered minor lag when scrolling. Similarly Calc took about ten times longer to open the above table but once open only hitched very slightly when scrolled.
Online forums seems to suggest Open Office to be a better choice of suite for lower specced Raspberry Pi models.
In contrast Raspbian’s built-in PDF viewer opened the consultation doc as swiftly as on the Pi 2 and I was able to mouse through it almost as smoothly.
Photo editing
Photo editing
Raspberry Pi 2 – Model B
The machine opens large images with ease, with this 3840 x 1200 image loading from the desktop in about 2.5 seconds.
However, photo editing using GNU Image Manipulation Program (GIMP) seemed less responsive. I experienced slight lag when switching between menus in GIMP and when using some of the editing tools, for instance Tools u2192 Transform u2192 Rotate. Here rotating the image by 110 degrees took about 33.5 seconds.
GIMP seemed perfectly usable, although I imagine delays could get tiring. Perhaps a lightweight alternative photo editor would make a better choice.
Raspberry Pi 1 – Model B
Loading images is slower, the image above opening in just over seven seconds.
Photo editing is somewhat painful. As with the Pi 2 lag is present when moving between menus. However manipulating images takes noticeably longer to the point where GIMP is not really usable. For instance, the above rotation operation took more than three minutes to get started, leading me to think I had locked up the system.
Mathematica
Mathematica
Raspberry Pi 2 – Model B
The reason the Raspberry Pi was created was to get children interested in learning about computers, and Raspbian comes with several education-focused programs.
One is Mathematica, a computational programming tool used in science, maths, computing and engineering.
On the Pi 2 the program booted up within 16 seconds.
Raspberry Pi 1 – Model B
As expected the application is far slower, taking about one minute and 34 seconds to open up.
Minecraft Pi
Minecraft Pi
Raspberry Pi 2 – Model B
Minecraft Pi, a free version of the hugely popular crafting and exploration game that’s bundled with Raspbian, ran without any problems.
The program generated its default small world within 20 seconds and navigating the blocky 3D world felt silky smooth, albeit with a short view distance.
Raspberry Pi 1 – Model B
Generating the world took about one minute but once in game it played as smoothly as the Pi 2.
Time to shutdown
Time to shutdown
Raspberry Pi 2 – Model B
Shutting down the desktop is nice and quick, taking between seven and eight seconds to power off.
Raspberry Pi 1 – Model B
The machine again was noticeably slower, with shutdown taking about 18.5 seconds.
Conclusion
Conclusion
The new model of the Raspberry Pi certainly goes a long way towards transforming the board into a PC you’d be happy to use each day. The improvement in performance over the first generation model B in many instances allows the Pi to run applications and sites that previously weren’t really feasible, and shows how far the board has come.
Another point to note is that Raspbian has not yet been optimised for the Raspberry Pi 2’s more powerful ARMv7-A architecture, something that Upton indicated should happen and which should further boost performance.
I had no major grievances in the short time I tested it and while the Pi might not match the performance of a budget laptop, it also undercuts their price by a considerable margin.
One caveat is that if you don’t have a display, keyboard, mouse and wireless dongle, setting up the Pi can cost more than the board. However, if that’s not an issue then the Pi 2 will do most things you expect from a PC and only cost you $35, which is a pretty tasty deal whichever way you slice it.
