But in the second half of next year, there will be a new socket for mainstream users: LGA-1156.
Meet Lynnfield, its also a 4-core/8-thread design with an 8MB L3 cache, just like the Core i7, but it plugs into LGA-1156. Instead of 3-DDR3 channels its got two and instead of QPI its got Intels DMI connecting it to the chipset. Its a lower bandwidth interconnect but Lynnfield doesnt need a ton of bandwidth between it and the chipset, the reason being its secret weapon: Lynnfield has an on-package PCIe controller.
There are 16 PCIe lanes on Lynnfield (presumably PCIe 2.0) and they can be used as two x8s or a single x16, so youll get 2-way SLI/CrossFire support assuming all licensing silliness is worked out. The close proximity of the PCIe controller to the CPU could mean some very interesting things for latency, if well designed Lynnfield could have the lowest latency CPU-GPU connection weve seen on a desktop PC. Whether or not thatll actually mean anything for real world performance remains to be seen, Id guess not but its neat to talk about nonetheless.
ขี้เกียจแปล แต่การออกแบบของ i5 จะต่างจาก i7 ตามภาพครับพี่น้อง
