The HPs 4720s notebooks are 17.3 inch notebooks that have good stylish out look and great features. The 4720s series have three pre built configurations that offer cost saving by way of being volume pre built. If you are looking for a 15 incha range from HP, you may like to take a look at HPs 4520s series.
Before we point out the common features of the prebuilt models 4720s-XT947UT, 4720s-XT948UT and 4720s-XT949UT, let us take a look at some of the common features of these notebooks.
The three pre built versions come with 4 GB of DDR3 memory that have speed grade of 1066 which implies the number of GT/s. These come with DVD+/-RW SuperMulti DL LightScribe. Generally, we would have expected them to come with Blu Ray Disc player, but, unfortunately they do not come with these.
The display is 17.3″ diagonal LED-backlit HD with resolution of 1600 x 900, perfect for entertainment and movie watching as well as your office ans home computing needs. The large screen helps you in case you need to open multiple windows simultaneously.
Now the difference part.
The HP 4720s-XT947UT has smaller 320 GB 7200 rpm SATA II hard disk, while both the HP 4720s-XT948UT and HP 4720s-XT949UT has higher 500 GB 7200 rpm SATA II hard disk. The extra hard disk will be useful in storing more videos, in case you need. But should not effect your ability to work with documents.
The most important difference is the processors in these three notebooks. They have the processor as follows.
HP 4720s-XT947UT – Intel Core i3-380M Processor (2.53 GHz, 3 MB L3 cache)
HP 4720s-XT948UT – Intel Core i5-460M Processor (2.53 GHz, 3 MB L3 cache)
HP 4720s-XT949UT – Intel Core i7-620M Processor (2.66 GHz, 4 MB L3 cache)
While the core i7 and core i5 are definitely better than the core i3, you should judiciously choose the processor based upon your need – as, they come at increasing cost. The most important difference in the core i3 Vs core i5 and i7 is the turbo boost function, which temporarily increases the processor clock frequency to cater for the increase in the demand for processing power.
