en.hw-lab.com 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.
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.
| P67 | H67 | H61 | P55 | H57 | H55 | |
|---|---|---|---|---|---|---|
| Processors supported | Sandy Bridge (LGA 1155) | Sandy Bridge (LGA 1155) | Sandy Bridge (LGA 1155) | Lynnfield, Clarkdale (LGA 1156) | Lynnfield, Clarkdale (LGA 1156) | Lynnfield, Clarkdale (LGA 1156) |
| PCI-e configuration | 1 x 16 PCIe 2.0 / 2 x 8 PCIe 2.0 | 1 x 16 PCIe 2.0 | 1 x 16 PCIe 2.0 | 1 x 16 PCIe 2.0 / 2 x 8 PCIe 2.0 | 1 x 16 PCIe 2.0 | 1 x 16 PCIe 2.0 |
| RAID | Yes | Yes | No | Yes | Yes | |
| USB 2.0 ports | 14 | 14 | 10 | 14 | 14 | 12 |
| SATA (SATA-3) ports | 6 (2) | 6 (2) | 4 (0) | 6 (0) | 6 (0) | 6 (0) |
| PCIe lines | 8 (5GT/s) | 8 (5GT/s) | 6 (5GT/s) | 8 (2.5GT/s) | 8 (2.5GT/s) | 6 (2.5GT/s) |
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.
