Intel will launch its new LGA1156 platform in September and the new platform consists of the Intel P55 chipset and the new Lynnfield processor architecture. Lynnfield is a stripped down version of Bloomfield, base of Core i7, where the changes include one less memory channel, down to two, and lower clock frequencies. Intel already revealed that Lynnfield will appear in the Core i7 family and according to PC Watch two of the first Lynnfield processors will be branded as Core i7.
Information from sources at OEM companies says that Intel will start off the Lynnfield venture with the following models.
Processor | Cores/Threads | Frequency | Turbo Boost | Cache | TDP |
|---|---|---|---|---|---|
Core i7 870 | 4C/8T | 2,93GHz | 3,60GHz | 8MB | 95W |
Core i7 860 | 4C/8T | 2,80GHz | 3,46GHz | 8MB | 95W |
Core i5 750 | 4C/4T | 2,66GHz | 3,20GHz | 8MB | 95W |
The three new models will will fit in the LGA1156 socket that the Intel P55 chipset will bring. The technical difference between Core i7 and Core i5 is that Intel has deactivated HyperThreading with Core i5. This limits the Core i5 processor to only four threads, while all Core i7 models can handle two threads per core.
All of the processors sport the same dual-channel DDR3 memory controller and supports up to 1333MHz memory speeds. Oddly enough, Core i5 models of Lynnfield lacks Virtualization support, which means they will be able to run the Windows XP “emulation” in Windows 7. Core i7 models of Lynnfield and the coming Clarkdale architecture will however, which feels odd to be honest.
You will be able to keep the Lynnfield-based Core i7 processors from the current Bloomfield-based seres through the model number, instead of Core i7 9xx the Lynnfield-based processors will be called Core i7 8xx and 7xx .
In the first quarter 2010, Intel will launch the first two Energy Efficient Core i7 processors. Core i7 860S and 750S will operate at 2.53GHz and 2.4GHz respectively, rated at 82W.
