The gradual extinction of dedicated discrete northbridge
X86_64 to the desktop, the chipset on the north side controlled the RAM bus (FSB), AGP video bus and PCI bus system.
The change was produced in 2003 AMD integrated the memory controller in the microprocessor and communication for the HT bus, PCI Express is relegated by serial PCI bus and AGP x8 disappears also begins to integrate the GPU on the motherboard (IGP) introduced in the northbridge by passing control to the VGA port, DVI and HDMI.
Southbridge is assigned to PCI, IDE, S-ATA, USB, Audio, COM, LPT, PS / 2.
Fusion APU in 2011 once again innovate to AMD (as in 2008 when he rode two die Intel dualcore and quadcore for Penryn launched AMD Phenom 4-core monolithic) integrating the GPU in the same package that contains 2 or 4 CPU cores and integrating the northbridge same with what remains is a southbridge-Hudson is his name on the mainboard, and the APU holder: CPU, IGP, BMI, chipset communicating with HT RAM and graphics ports IGP for the PCIe 2.0 also commands North Bridge integrated into the APU.
The speeds are increased graphics performance and energy consumption TDP drops from 32/40 nm chip current and recent generation RadeonHD 6500.
Intel anticipated the merger in 2010 with its Westmere and Arrandale but not yet integrated the chipset and Sandy Bridge now on the mainboard chipset P67 upper-middle range of micro override the IGP graphic outputs and do not allow prevents the use of improved resources renderer and low watts dissipated.

I thought this was a web operating system.
Yes it is. And the hardware that houses the permanent operating systems running in RAM is too.
What do you think of the gradual extinction of dedicated discrete northbridge?
