List of LGA 1156 processors

I pulled this from another forum that I am on. Just thought I would share some of this info w/ my fellow simmers to see whats coming next. I know a bunch of us just upgraded to the current i7 with hopes that it could run FSX with no problems. Unfortunately, we have come to see that its still not happening yet. Do you think this new wave of processors will do it? Core i5 & i3 Processor (Clarkdale) Information ThreadNehalem Microarchitecture is an Intel processor microarchitecture that succeeded Core Microarchitecture and was released in November 2008. It is based on Core Microarchitecture with several new technologies:

• A new processor bus, called Intel QuickPath interconnect, that features point-to-point serial bus topology, similar to PCI Express and HyperTransport (AMD adopted it in 2003).
• IMC (Integrated Memory Controller) supporting up to triple channel DDR3.
• Performance improvement by adding new functions such as
  • SMT (Simultaneous Multi-Threading), the revival of HyperThreading Technology in Pentium 4
  • New 3-level cache hierarchy, L2, L2 (new 256KB/core), L3 (8MB fully-shared)
  • New 2-level TLB (Translation Lookaside Buffer) hierarchy
  • L2 branch predictor

The desktop versions of the Nehalem processor are (in chronological order):

• Bloomfield: The current Core i7 processors. 4 cores/8 threads, LGA 1366, 45 nm.
• Lynnfield: Core i7 and i5 processors to be released on September 8, 2009. 4 cores/(up to) 8 threads, LGA 1156, 45 nm.
• Clarkdale: Core i5 and i3 processors to be released in January 2010. 2 cores/(up to) 4 threads, integrated graphics core, LGA 1156, 32 nm.
• Gulftown: Core i9 processors expected in Q2 2010. 6 cores/12 threads, LGA 1366, 32 nm.

(The 32 nm version of Nehalem is dubbed Westmere.) Then Sandy Bridge Microarchitechture will succeed in 2010. Most people in this forum will be concerned with Clarkdale (mainstream) and Lynnfield (high-end). Bloomfield will be limited to extreme high-end, as well as Gulftown. System Architectures for Nehalem Processor The current Core i7 (Bloomfield) system architecture is very similar to the AMD platform: memory controller is integrated in CPU; CPU and IOH (I/O Hub) are connected by QuickPath InterConnect (similar to HyperTransport); IOH and ICH (I/O Controller Hub) are connected by DMI (Direct Media Interface) (~PCI Express x4).

In the upcoming Core i7 and i5 (Lynnfield), PCI Express controller is integrated in CPU; CPU and PCH (Platform Controller Hub) are connected by DMI. In Core i5 & i3 (Clarkdale) further includes graphics core and video streams are transported to Display Interface Controller in PCH via FDI (Flexible Display Interface).

Branding Scheme The most important features that distinguish between i7, i5 and i3 are:

• Number of threads (instead of the number of cores)
• Turbo Boost Technology

Roughly speaking,

• Core i7 = 8 threads, Turbo Boost (4 cores [Lynnfield])
• Core i5 = 4 threads, Turbo Boost (4 cores [Lynnfield] or 2 cores [Clarkdale])
• Core i3 = 4 threads, no Turbo Boost (2 cores [Clarkdale])
