Computer Models Comparison - Essay Example

In this respect, this paper provides a review (comparison) of three amongst the leading computer models that an organization can choose from, namely: HP Pavilion p7-1030, Velocity Micro Edge Z40, and Lenovo ThinkStation S20 (Adams, 2011). The three models are compared on the basis of their price, external features, internal features and performance. Subsequently, recommendations are made on the best model between the three for this organization to purchase. Pricing is a key element to be considered while purchasing a computer product.

Retailing at $3,665, the Lenovo would be the costliest of the three models, followed by Velocity which goes for an approximate $1199. Going for $580, Pavilion is the cheapest of them all; about $2000 and $500 cheaper than Lenovo and Velocity respectively. Regarding the external features, Velocity has eight USB 2.0 ports. With that number, it falls short of Lenovo by four ports while beating Pavillion by two ports. On the upper part of the front panel, the Pavilion further has multimedia card reader ports (MMC, XD, MS/Pro, SD and Compact Flash).

At the back all the three have an Ethernet port, three audio jerks (audio-in, microphone in and audio-out) as well as a DVI video and VGA for connecting the desktop to an external display or monitor. They also come with a wired USB optical mouse and USB keyboard. The one notable downside about Velocity is that, unlike the other two, it may not come with a monitor (Adams, 2011). Internally, the Pavillion is loaded with a 1TB 7200rpm hard drive and a PCIe Mini card which delivers 802.11n Wi-Fi therefore negating the need for long Ethernet cables when connecting to the Web (Adams, 2011).

It also has 8GB of DDR3 RAM which although more than sufficient, occupies the only two DIMM slots available, thereby leaving no room for expansion unless the user chooses to do so by removing one or both pre installed memory sticks. Similarly, the Velocity feature 1TB, 7200rpm hard drive, but does scale down on the memory to provide 4GB of DDR3. Having a 500GB SATA 7200 rpm hard drive and 2GB of DDR3 RAM, Lenovo appears to scale down on two of the most essential internal features, but on the other hand, the model proceeds to compensates for this by providing ample space for two more memory sticks and two more internal hard drives.

Of noteworthy, as far as internal features are concerned, the make comes with pre-installed software. In terms of operating system, all the three come with a pre installed Genuine Windows 7 Professional 64bit. Similarly, they all come with a pre installed starter version of Microsoft Office 2010. In terms of software, the only major difference between the three is that of the anti virus software pre installed in each of them. Whereas the pavilion features a 60-day trial of Norton Internet Security 2011, Lenovo comes with a 30-day trial McAffee Internet Security package.

However, unlike Pavilion, Lenovo’s McAffee is merely made to lie on the hard drive uninstalled. This is seen as a good thing by many, because it saves organizations the steps of cleaning their PCs if they happen to use a different solution (Adams, 2011). Performance Regarding the performance, the ordinary office setting does not allow for computer games and gaming tests. And whereas it is
