Haswell-EP models with ten and more cores support cluster on die (COD) operation mode, [75] allowing CPU's multiple columns of cores and last level cache (LLC) slices to be logically divided into what is presented as two non-uniform memory access (NUMA) CPUs to the operating system. By keeping data and instructions local to the "partition" of ...
reengineered P6-based microarchitecture used in Intel Core 2 and Xeon microprocessors, built on a 65 nm process, supporting x86-64 level SSE instruction and macro-op fusion and enhanced micro-op fusion with a wider front end and decoder, larger out-of-order core and renamed register, support loop stream detector and large shadow register file.
Advanced Vector Extensions 2 (AVX2), also known as Haswell New Instructions, [24] is an expansion of the AVX instruction set introduced in Intel's Haswell microarchitecture. AVX2 makes the following additions: expansion of most vector integer SSE and AVX instructions to 256 bits
Two Serial ATA (SATA) 3.0 controllers are integrated into the X99 chipset, providing a total of up to ten ports for storage devices and supporting speeds of up to 6 Gbit/s per port, with hardware support for the Advanced Host Controller Interface (AHCI) logical interface. Each SATA port may be enabled or disabled as needed.
AMD was the first to introduce the instructions that now form Intel's BMI1 as part of its ABM (Advanced Bit Manipulation) instruction set, then later added support for Intel's new BMI2 instructions.
Haswell and Broadwell feature a Fully Integrated Voltage Regulator. Broadwell (previously Rockwell) is the fifth generation of the Intel Core processor. It is Intel's codename for the 14 nanometer die shrink of its Haswell microarchitecture. It is a "tick" in Intel's tick–tock principle as the next step in semiconductor fabrication.
The microarchitecture is the same as in the six-core Gulftown/Westmere-EP processor, but it uses the LGA 1567 package like Beckton to support up to eight sockets. Starting with Westmere-EX, the naming scheme has changed once again, with "E7-xxxx" now signifying the high-end line of Xeon processors using a package that supports larger than two ...
Tick–tock was a production model adopted in 2007 by chip manufacturer Intel.Under this model, every new process technology was first used to manufacture a die shrink of a proven microarchitecture (tick), followed by a new microarchitecture on the now-proven process (tock).
