Intel Sandy Bridge. Expansion

Were are waiting for another update form Intel which will take place in 2011 — Sandy Bridge processors. The first encounter — expansion.

Processors will require a new Socket (LGA 1155) and absolutely new motherboards with Intel’s 6th generation of system logic.

Socket 1155
As a result, new processors would also entail the purchase of a new motherboard. Intel’s 6th generation system logic will bring two SATA 3 ports, PCIe 2.0 with throughput of 5GT/s, but still not USB 3.0. Motherboard manufacturers will have to use different USB 3.0 controller.

Brief specs of Intel’s system logic

P67 chipsets will have some integrated graphics restriction, instead, it will provide two PCIe 2.0 slots for discrete cards. With a discrete graphics card activated, an integrated graphics core will be disabled. In addition, P67 has unlocked memory multiplier which allows to use memory setting up-to DDR3-2133, at the same time, H6x chipsets’ memory controller is tied to specification (maximum is DDR3-1333). Another important change — PCIe throughput increased up-to 5GT/s. PCIe bus of current Intel’s system logic has throughput of 2.5GT/s, which limits the exchange of information to 250Mb/s in one direction. 5GT/s of 6th series chipsets will provide PCIe line with the throughput of 500Mb/s in both direction (total PCIe x1 bandwidth is 1Gb/s).
At this point, the introduction can be considered as finished, the next article about Sandy Bridge will be entirely devoted Intel’s new micro-architecture.
