Haswell

Haswell frontend. Note the unified decode queue compared to the SMT-split queue of Ivy Bridge.

Haswell follows Ivy Bridge, the die-shrunk "Tock" of Intel's Nehalem. It will be manufactured on a 22nm process, and is scheduled to be released in Q1 2013. Haswell will feature transactional memory, and represents a major step forward in power reduction, largely through new ACPI sleep states ("S0ix states") and improvements throughout the associated chipset ("Shark Bay"). Haswell supports AVX2 instructions (including the FMA set) on two ports, doubling both single and double-precision AVX floating point flops over Ivy Bridge.

Haswell employs an 8-wide ALU.
