This laptop is powered by an Intel Pentium N3540 quad core processor with 1M cache, a base clock of 2.16 GHz and a burst frequency of 2.66 GHz. Alternatively, you can choose an Intel Celeron N2840 processor with basically all the same features as the Intel Pentium, except for a burst frequency of only 2.58 GHz. The other hardware here include a 4 GB RAM, a 500 GB SATA HDD 5400 rpm hard disk and an Intel HD graphics card. Windows 8.1 64 bit is used as OS. The Inspiron 15 weighs about 2.4 kg and is slightly over 2 cm thick, which provides well for moderate portability.
