Intel QM57 chipset review
The Intel QM57 chipset is intended for the mobile notebooks with intel core i3, core i5 and core i7 processors. In intel’s lingo this chipset is called Platform Controller Hub or PCH. The QM57 chipset connects to the processor using the 10Gb Direct Media Interface (DMI) Bus.
The block diagram ( courtsey intel) throws some light on the intel QM57 chipset architecture.
The QM57 has eight PCI Express 2.0 ports which should be enough to support most of the mobile platforms. It has support of for 6 SATA 3.0 Gb/s, although it will be rare that all of them will be used in a typical notebook design. Its 2 EHCI Controllers support upto fourteen USB 2.0 ports. Most of the today’s notebooks typically have 4 or 5 USB ports, though some of them may use more than 5, for some internal functionality.
The QM57 has direct support to the HDMI, DVI, VGA, SDVO and/or DisplayPort. This reduces the external hardware required to design a notebook or an embedded product with display support. Besides that, the QM57 supports following extra connectivity.
– Integrated Intel Gigabit Ethernet (10/100/1000) PCI-Express
– Intel HD Audio
– Intel Active Management Technology (AMT)
– PCI 2.3
– LPC bus
– Intel I/O Virtualization (VT-d)
– Intel Trusted Execution Techology
– Intel Rapid RAID 0/1/5/10
The QM57 chipset has a TDP rating of 3.5 Watts, and the size of the package is 25x27mm.
