Intel Corp. earlier this month published the first details about its next-generation micro-architecture code-named Haswell. The forthcoming chips will feature new instructions that accelerate a wide number of applications and workloads.


Intel’s Ivy Bridge and Haswell microprocessors are projected to offer increased performance amid moderate power supply. Those chips will enable new class of mobile computers that Intel calls ultrabooks. With Haswell, Intel promises to change the mainstream laptop thermal design point by reducing the microprocessor power to half of today’s design point, which means something like 15W - 18.5W. The chips are also expected to offer much improved integrated graphics cores.

These new set of instructions are build upon the instructions coming in Intel micro-architecture code name Ivy Bridge, including the digital random number generator, half-float (float16) accelerators, and extend the Intel Advanced Vector extensions (AVX) that launched in 2011.

The instructions fit into several categories:
