… in particular, netbooks.
I was asked by a family member to help choose a netbook. For those who don’t know, netbooks are small, cut-down notebooks (laptops), with just enough processing power to do email and surf the web. They typically have a 10 inch screen, a single core CPU (Central Processing Unit, the brain), and an integrated GPU (Graphics Processing Unit, which draws all the graphics on the screen), 1GB of RAM (Random Access Memory, short-term memory), 160GB Hard Drive (long term memory) and no CD drive. As a result, they’re generally cheaper than their larger notebook cousins but, as is the case in many arenas, you get what you pay for.
So, out of the veritable smorgasbord of netbooks on offer, I had to decide which one to recommend. Having ascertained how the netbook was to be used, I could start min-maxing.
Er, what’s min-maxing, you might wonder.
Well, it comes from game character creation where a player has a certain number of attribute points to divide between various character traits, such as strength, wisdom, dexterity, etc. and they apportion those points in such a way as to create the best character possible for the role in question.
So, if they wanted a brutish figher, for instance, they would put most points on strength and only a few, if any, on wisdom. Or, if they wanted a roguish character, dexterity would receive a lot of points (to improve the character’s chances of success at sleight of hand) and not so many on the other traits. Of course, the player could spread the points out evenly amongst all the traits, in which case the character would tend to be a jack-of-all trades (but master of none).
Now, as far as I’m aware, netbooks don’t tend to have dexterity or wisdom attributes (although, arguably they do have strength), but they do have other attributes which I needed to take into account.
The main ones are: CPU speed, GPU speed, RAM, OS (Operating System), hard drive size and battery life.
Generally, with a computer, there needs to be a balance between certain attributes if the machine is to perform to the best of its ability.
For example, if the CPU is fast, but the GPU is slow, the extra speed of the CPU will be wasted while the GPU is struggling to draw all the graphics.
Conversely, if the CPU is slow and the GPU is fast, the GPU will be twiddling its proverbial thumbs while the CPU is struggling to supply it with the data needed so it can draw to the screen.
If the netbook only has a small amount of RAM, both the CPU and the GPU will be putting their feet up while the hard drive thrashes about paging data in and out of RAM.
Lastly, the efficiency of the OS (Windows XP or Windows 7) can have an impact on performance, so I had to weigh up the benefit of a slightly faster and less resource hungry Windows XP (which won’t be supported by Microsoft beyond 2014) against the slightly slower and less efficient, but potentially better supported Windows 7.
So, having looked at all the netbooks from a variety of websites, I plumped for one within budget which had a reasonable CPU (although not the fastest) as it had a better GPU than that of the faster CPU netbook. I guestimated this combination would provide a smoother user experience overall, especially on graphics-heavy websites. And since this machine was just going to be used for email and surfing, it didn’t need a huge hard drive to store a lot of data. However, it did need a reasonably long battery life, as it was to be used whilst away from home, and it also needed more than four years of Windows Updates if it was to be used for the projected time span.
Well, the netbook in question has now been ordered, so we’ll see in due course whether my min-maxing efforts will have paid off.
