Mac or Windows? The decades-old question remains unsolved. A lot of times the decision is not based on computer alone, but rather on user preference and finances. This blog will explore the which computer is best for computer science students and how to choose specs based on long-term need while in the program.

System: Mac vs. Windows

Recommended: Mac

The advantage of Mac is that it is a UNIX-based system – and computer science courses are mainly taught in UNIX. Most development software is made for UNIX-based systems, and it is the most widely used in the industry. Moreover, users can still install Windows on a Mac using either Parallel or Bootcamp (free), and it will run as it would on a native Windows computer. Mac systems are more stable, with barely any sudden shut-offs, no forced system updates and barely any viruses. However, with all these benefits, the downside for a Mac is the cost. The graphics card, in general, is not as good as the one on a Windows computer within the same price range, although it is more than enough for computer science courses.

The advantage of Windows systems is that most programs are compatible because almost everything is designed with Windows in mind. However, that is not the case for programmers, and UNIX systems are undeniably better for developers. With a Windows system, you can set up dual-boot so you can use your system’s full capabilities in both Windows and Linux in order to use a UNIX system. Alternatively, you can set up a virtual machine for quick access to both systems at the cost of performance. You can buy a PC inexpensively and still have a good system – and Windows is far better for gaming. While Windows can still be used by developers, UNIX systems are best and I would highly recommend setting up a way to use one if you plan on buying a PC.

Macbook, MacBook Pro or MacBook Air?

Recommended: MacBook Pro, Minimum: MacBook Air

Apple created three product lines for laptops. The Macbook and Macbook Air are suitable for users who are not heavy computer users, while the MacBook Pro is better for users who expect more computing power from their laptop. Even though Macbook and MacBook Air are similar for the user group, each product line still has its differences and advantages.

MacBook vs. MacBook Air

MacBook is more compact and thinner, with a screen size of 12’’ with Retina display. Macbook only weighs two pounds and is only 13.1 mm in width. It has a more powerful touchpad that is bigger and supports force touch. The keyboard design is also more advanced. However, a MacBook is more expensive than a MacBook Air. It has a less powerful CPU and only one USB-C port, which means that users would have to buy adapter hubs for HDMI or USB 3.0. In short, the MacBook Air is cheaper, has a more powerful CPU than a MacBook and has more connection ports. However, it is heavier, does not have Retina display and has a less advanced keyboard and touchpad.

Macbook Pro

Ultimately, the MacBook Pro is the go-to product for students who want to use their computers for computer science classes, mainly because MacBook Pro is more powerful. The 13-inch base model comes with 2 GHz CPU while the base model for MacBook is only 1.3 GHz. The integrated graphics card is better, and the MacBook Pro also gives user options to install i7 CPU as well as an AMD discrete graphics card.

Now, even though a MacBook Pro is the best computer for computer science students, there are still more questions need to be answered:

  • How much memory should one get?
  • How much storage should one get?
  • Should one get the discrete graphics card?

How Much CPU Do I Need?

Recommended: i5 Chip

An i5 chip is really good enough. You would not need an i7 chip for computer science classes. However, if you have the finances, then the more power, the better, of course! But for regular software development, programmers do not need i7 to code and build software. Unless you plan to intensively use the CPU for specific programs, like Microsoft Hololens Emulator, then the core i5 is good enough.

How Much Storage Should I Get?

Recommended: 500 GB, Minimum: 256 GB, Overkill: 1 TB

As for storage, 1 TB would be way more than enough while 128 GB would not be enough at all. Mac users should also install Windows on their Macs through BootCamp because some software works better on Windows (such as Visual Studio). With 500 GB, after splitting the storage by using two systems, there would be storage left for the system.

It is also recommended that users buy an external hard drive, because you won’t need all your files with you all the time on your computer. Most files are archived so you can store them on an external hard drive, which is a lot cheaper than the built-in storage. The gist of choosing storage is to find the optimal size that is able to store all the files you need with you and then buy an external hard drive to store everything else.

What Screen Size Should I Choose?

Recommended: 15 inches, Minimum: 13 inches

As computer science student, you will have multiple windows open, such as a window full of code, a window of the running program, a browser window and a notes window. Having a bigger screen is always a better choice. As a matter of fact, most professional developers have at least two computer monitors.

How Much Memory Do I Need?

Recommended: 16 GB, Minimum: 8 GB, Overkill: 32GB

In general, 8 GB of memory is just enough. Running a development environment, a Microsoft Word, a Chrome window and an Adobe Acrobat DC can be handled by 8 GB of RAM. However, if you are running parallel software (such as a Windows system on a MacOS system) or if you plan to run multiple virtual machines, then 16 GB would be a good amount of RAM.

If your computer science emphasis is big data analytics, then having 16 GB RAM would help the speed of processing data since there would be 8 GB more memory for the CPU to use. But that is not essential – you can still use 8 GB RAM to process data.

Which GPU Should I Get?

Recommended: AMD Radeon, Minimum: Intel Graphics, Overkill: External Graphics Card

Mac uses either an Intel graphics card or an extra discrete AMD graphics card for better performance, which is more expensive. You will not need a discrete graphics card for any of your computer science class; however, if you can afford one, then get a discrete graphics card because you might need it for other things. If you want to learn intensive graphics modeling, then a discrete graphics card would be a good companion. If you are learning parallel computing, then the GPU and CPU running side by side would speed up the program execution time.

What Software Do I Need?

Grand Canyon University provides its students with a lot of powerful free software that otherwise would be very expensive. For instance, you do not need to worry about buying Microsoft Office Suite or MS Access SQL Server. All development tools from JetBrains, including CLion for C/C++ language development and ReSharper for code editing, are also free to GCU students in the program. You will need to download the free Adobe Acrobat DC app for your Mac because you need that software to be able to view documents like your electronic textbook.

Think Long-Term When Investing in Your Computer

If you decide to buy a Mac, one advantage is that it will typically last longer than a Windows computer. Expect that you will be using your Mac computer for at least six years or more, barring any accidents or damage. Get a case or sleeve as well as a keyboard cover for your Mac to protect it so cosmetically it would still look great after years of use.

Since you will be using your Mac for an extended period of time, invest in it! If you have the money to pay for a model that has better specs, do it. As an example, 8 GB of RAM may sound adequate upfront, but as time goes on, it will not be enough. By the time you want to have 16 GB of RAM, you will likely have to buy a new computer. Therefore, think long-term when you buy your computer – and buy it with the specs that will be enough throughout your entire program.

The Buyer’s Decision

If you have a computer right now, wait to buy a new one. A regular computer is good enough for the first two years of computer science classes. It may not have the best performance, but it will definitely be good enough. After your first two years of college, if you are well into the deeper levels of computer science, then consider buying a really good Mac for heavier usage.
