Recommendations for your personal computer

Acquiring the Equipment

For second year (3rd semester) bachelor-level students, it is obligatory to have a personal laptop, but we highly recommended you have one from the beginning of your studies at EPFL.

You can purchase the equipment you need via Poséidon (, as soon as you are registered and have an EPFL e-mail address.

Of course, you may choose to purchase the necessary equipment on the open market, but be careful about the after-sales support and the guarantees (often valid only for one year, with an option to extend; even though federal legislation requires the material be guaranteed for two years).

The choice of an operating system is not important
Unix/Linux is the most commonly used in computer science, but Windows and Mac OS also work well. (However, as of today, iOS and Android are not yet sufficient.) You can easily install a virtual machine on Linux or Windows, which will enable you to use another operating system, or you can configure your computer to boot up a choice of the three systems.
The choice of a brand, as well, does not matter
Asus, Dell, HP, Lenovo, MSI, Razer, Surface (among many others) all provide quality products. (In general, Apple products are more expensive for the same level of service.) Currently, Poséidon offers only products from Apple, HP and Lenovo.
the processor
the brand – Intel or AMD – does not matter; recent processors have four or six cores.
The graphics processing unit (GPU)
If you are interested in all the aspects of graphics (images, videos, etc.), use a dedicated graphics card Nvidia or AMD. For all other uses, the Intel chips with integrated graphic processors are sufficient.
Anything less than 4GB is insufficient, and 8 to 16 GBs are preferable.
Wi-Fi connection
essential, preferably with ac or n.
Data storage
Today, it’s almost mandatory to have a SSD, the recent OS being optimized for this type of storage. Most computers have SSD, so it’s not really a problem anymore. If you have an old computer, it’s advisable to replace the hard disk with a SSD and use the hard disk as external storage. SSD of 256 GO or 512 GO cost very little nowadays.
Screen, batteries, weight
You must optimize the three. The larger the screen is, the more the weight and power consumption increase; so to ensure energy autonomy, a large battery is necessary, but it is also heavy. In general, with a larger laptop, when needed you can change the hard disk and the battery (which enables you to augment the autonomy, to replace it with a second one if needed and to replace the battery when it ‘dies’.)
important information
Keep in mind that a laptop is fragile, therefore, we recommend that you purchase a protective case and perhaps also a sac especially adapted to your laptop; avoid dropping it and above all be careful with the screen.
At home
it could be useful to have a large screen (more than 20”) and an external (standalone) storage system are useful (for example, a simple box that holds one or two empty disks and that connects to your computer via a USB key 3.0 or another fast connection; this is easy to use, flexible and an inexpensive solution, an example is ”Icebox”). By storing your data separately, you will be able to keep a copy of all your data, with an unlimited storage capacity. You also have storage available in the EPFL network.
