AMD Phenom II X4 P920 quad core processor
The Phenom ii quad core P920 is a sluggish processor especially in single threaded application, mainly due to its low frequecy. At 1.6 GHz you will find it slow for processor intensive single threaded applications. It does not has any level 3 cache ( All mobile Phenom ii processors come without level 3 cache – though desktop versions come with Level 3 cache).
The plus point with the AMD Phenom II X4 P920 is its low thermal rating of 25 Watts. In multithreaded computing the 4 cores may be just enough for many of your needs.
To compare with the similarly clocked intel Core i7-720QM ( which is also rated at 1.6 GHz), Intel core i7-720QM is faster than the Phenom N920 is due to the turbo boost and the L3 cache. The only reason for you to go for the AMD Phenom II X4 P920 could be the price advantage and its low power consumption. At 25 Watts TDP, the Phenom ii P920 leads to design of the notebooks with higher battery life while consuming low power helping keep the environment green.
Manufactured with the 45nm technology, the P920 does support hardware virtualization. It has a total of 2048 KB of Level 2 Cache ( 512 KB for each of the four cores).
The P920 has integrated DDR3 memory controller. The integrated memory controller design partially offsets the lacuna created by the absence of the L3 Cache.
The communication with the chipset is through the 3600 Million Transfer per second ( MT/s) hyperTransport Bus.
