PC Solutions Performance Rating System
Our aim is to help you make an informed choice when purchasing a new or refurbished, laptop, notebook, netbook or desktop computer.
The computer industry is notorious for using gobbledegook, numbers and phrases that most folk don’t have a clue about. Most computer buyers just want to make an informed buying decision, without have to have an IT degree just to understand and comprehend the marketing material!
At PC Solutions, we felt that the complex nature of PC hardware often led to confusion for end users, questions like 'is a Pentium 4 better than a Pentium 7' and 'is this laptop better because it has a bigger hard drive?' were often leading to complex answers (there have been at least seven different processor architectures with the Pentium brand - and three of them are just called 'Pentium') we felt that developing an easily comparable Performance Rating would allow the users to check and differentiate between different devices.
The Performance Rating Score is shown on every laptop, desktop, notebook or netbook that we sell both in our retail & web shops (fully searchable).
The Performance Rating only takes into account the core components that can greatest influence on system performance. The system Performance Rating calculation it outputs a number greater than 1, the higher the number the greater the system performance.
The mathematics behind the rating are simple, but more to the point they are consistent - every device, laptop, desk top, netbook or notebook are rated according to the same formula, so a Performance Rating of 7 is always better than a Performance Rating of 5.
The calculation starts with Amount of Processor Cores + Amount of RAM (in GB's) + The Basic Core Frequency of the Processor
For instance my laptop has 2 Cores running at 1.6Ghz with 8GB of RAM = 11.6
A standard netbook will have 1 core running at 1.6Ghz with 1GB of RAM = 3.6
A chip bonus is added based on the processor type:
a single core processor gets no bonus
a core2duo gets 3
a Sandy Bridge i5 gets 5.
My laptop has a core 2 duo processor so it get an additional 3 = 14.6
Our example netbook has an atom processor with gets a penalty of - 0.5 bringing the score to 3.1
Finally additional bonuses are awarded for specific hardware that boosts performance.
Solid State Disks which are super-fast hard drive replacements get an extra 3 and Hyper Threading processors gets an extra 0.5, per core.
The laptop that I use is fitted with an SSD so my laptop is awarded an additional 3 bringing my final score to 17.6
The netbook however has no addition performance boosting hardware, leaving its score at 3.1
We hope this has helped you understand a part of the technical aspect of our Performance Rating and will make the selection of your new or refurbished laptop a little bit easier. |
