Core i?
Friday, October 9, 2009 at 10:10AM Core i ?
So there has been some mix ups about the deal with Intel’s new Core i series CPU.
Right now on the market you gonna be seeing Core i7 9xx, Core i7 8xx, Core i5 6xx, Core i5 
Ok so what’s the difference in these guys?
Here's a no so simple run down of what’s what.
Core i7 9xx
The i7 9 is the high end beasts of the CPU based on the Bloomfield core. These are socket 1366 and are linked to the X58 boards. They have hyper threading on all 4 cores and use QPI interface to the mother board (on chip memory controller).
Core i7 8xx
Now you may think that Intel would space these out, i7 high end, i5 a bit lower and so on, but they didn’t.
The core i7 8xx series is based on the Core i5 CPU, while at the same time being sold as Core i5. Unlike Bloomfield (Core i7 9xx) , it does not have a QPI interface but directly connects to a southbridge and other devices using the Direct Media Interface and PCI Express links in its Socket 1156. Core i7 processors based on Lynnfield have hyper-threading, which is disabled in Core i5 Lynnfield processors. It runs the same socket as the Core i5 which is 1156, which can be found on the x55 motherboards
Core i7 6xx moblie
Clarksfield is the mobile version of Lynnfield and available under the Core i7 Mobile brand, as part of the Calpella platform. It was released at the Intel Developer Forum on September 23, 2009.
The second mobile Core i7 processor family will be Arrandale, sold as the Core i7-6xx processors and featuring an integrated graphics processing unit but only two processor cores, half of Clarksfield. Clarkdale (microprocessor), the desktop version of Arrandale, will not be sold as Core i7, but only as Core i3 and Core i5.
Core i5
The Core i5 750, which is a 2.66 GHz quad-core Lynnfield processor with Hyper-threading disabled. Lynnfield Core i5 processors have an 8 MB L3 cache, a DMI bus running at 2.5 GT/s and support for dual-channel DDR3-800/1066/1333 memory
The Core i5-5xx mobile processors will be named Arrandale and based on the 32 nm Westmere shrink of the Nehalem microarchitecture. Arrandale processors have integrated graphics capability but only two processor cores. Their release is expected in late 2009 or early 2010, together with Core i7-6xx processors based on the same chip. The L2 cache in Core i5-5xx processors is reduced to 3 MB, while the Core i7-6xx will use the full cache.
Core i3
Intel Core i3 was announced on June 18, 2009 to be the name of a future Intel Core processor family and later confirmed by Intel as the 'entry-level' processor in the revamped Core line-up.
This will position the Core i3 as the junior processor in a 'good-better-best' scenario, beneath the mid-range mainstream Core i5, the more powerful high-end Core i7,
Future core's
Core i9
The final addition to the Nehalem based Core processor lineup will be the Core i9 brand in 2010, with the six-core Gulftown core inside. Gulftown uses the same socket as Bloomfield, so Core i9 can be seen as an upgrade to the Core i7-9xx series.
Thanks to wiki and Google for explaining it to me!
