In April 2022, press reported on "hints" that Intel was working on Alder Lake-X. [13] [14] Intel officially announced the HX processor series on May 10, 2022, including Core i5, Core i7 and Core i9 models, [10] when Intel announced "seven new mobile processors for the 12th Gen Intel Core mobile family at its Intel Vision event. [15]
In each generation, the highest-performing Core i7 processors use the same socket and QPI-based architecture as the medium-end Xeon processors of that generation, while lower-performing Core i7 processors use the same socket and PCIe/DMI/FDI architecture as the Core i5. "Core i7" is a successor to the Intel Core 2 brand.
Ivy Bridge is the codename for Intel's 22 nm microarchitecture used in the third generation of the Intel Core processors (Core i7, i5, i3). Ivy Bridge is a die shrink to 22 nm process based on FinFET ("3D") Tri-Gate transistors , from the former generation's 32 nm Sandy Bridge microarchitecture—also known as tick–tock model .
Maximum supported memory speeds are expected to be DDR3-1600 and DDR4-1866. [14] [15] Up to 24 core and 48 threads, up to 60 MB of L3 cache and 32 PCI Express 3.0 lanes, with 115–165 W TDP. LGA 2011-v3 socket: Intel i7 6800K. Broadwell-EP: to be marketed as Xeon E5-2600 v4 etc., while using the C610 Wellsburg chipset platform.
The I7-965 XE and I7-975 XE have separate unlocked multipliers for memory and cores. Core clock above those in the table are not guaranteed by Intel. [3] A CPU Clock Speed of 6.158 GHz has been achieved. [5] Memory rates above those in the table are not guaranteed by Intel. [3] Memory Speeds of DDR3-2133 have been achieved. [6]
Memory hierarchy of an AMD Bulldozer server. The number of levels in the memory hierarchy and the performance at each level has increased over time. The type of memory or storage components also change historically. [6] For example, the memory hierarchy of an Intel Haswell Mobile [7] processor circa 2013 is:
Limits on physical memory for 32-bit platforms also depend on the presence and use of Physical Address Extension (PAE), which allows 32-bit systems to use more than 4 GB of physical memory. PAE and 64-bit systems may be able to address up to the full address space of the x86 processor.
Bottom view of a Core i7-2600K. Sandy Bridge is the codename for Intel's 32 nm microarchitecture used in the second generation of the Intel Core processors (Core i7, i5, i3).The Sandy Bridge microarchitecture is the successor to Nehalem and Westmere microarchitecture.
