My desktop is faster than my Laptop, why is this so?
I’ve been using a laptop and desktop which have “the same” i7 processor but the desktop performs so much better. How can this be?
For a start, they are both i7 processors but they aren’t the same. Without opening either of them up, the following are likely explanations.
– as the laptop is much older, it will probably not have a 4th generation processor. The recently purchased desktop definitely has a 4 th generation i7 processor. The newer processors are faster, to the extent that a 4th Generation i5 may be faster than an older i7.
– mobile processors are optimised for power saving rather than speed, so tend to be a bit slower
– mobile processors slow down when running on battery to conserve power.
What should I do?
Unless you are buying a new computer, probably nothing.
If you are buying a new computer, make sure you chose one which meets your needs. A cheap laptop or an old one may struggle with tasks like video editing. For more on Intel processors, have a look here. http://www.pcmag.com/article2/0,2817,2404674,00.asp
If you are overwhelmed by mobile device jargon, here is a quick reference guide.
An Operating system is the software control centre of a device. The operating system coordinates everything a device does, from printing to letting you type a document. It controls the other apps on your device, starts it up and performs the basic functions you take for granted.
Android, Gingerbread, Jelly Bean, Kit Kat : Android is a popular operating system or master/coordinating software for non – Apple phones and tablets and the delicious range of goodies are various versions , with Kit Kat being the newest at the time of writing.
iOS : operating system for Apple iPhones, iPod Touches and iPads

Feel as if you are sailing through a fog? Fogs on the Seas of Technology are not wet, rather they are made of words, acronyms and jargon which cause many
travellers to feel lost and confused. Often even those selling the technology have not received enough training to shine a light on some of these. A perfect example is the SAR rating of a phone. Many will tell you that SAR stands for Specific Absorption Rate and give scientific definitions. ( If you are scientifically minded, you can find those online in Wikipedia and other online sources e.g.
However, some phone sales staff don’t know what it is! You don’t need to remember, the science in detail. Basically, it is a measure of the user’s radio frequency exposure from using the phone. It appears the scientific jury is still out on the possibility of health effects from such exposure. All phones sold in Australia must conform to a standard similar to those in other developed countries so many people believe any of them are safe to use. However, if you feel concerned about it, you can choose to use a hand-free or speakerphone feature to limit the time you have the phone close to your head and/or you can select the phone which has the lowest SAR rating of these which meet your other needs. The SAR rating of Australian phones must be published in the instruction manual and they can usually be found online as well. My own phone was selected because I loved it but it’s relatively low SAR rating was one feature that attracted me.
