At the beginning of 2013, Intel will also offer HTM, with its Haswell processor. Everyone from Intel openly admitted as much when asked directly at SC11. Supposedly, Intel will soon announce the new TM instructions that will be added to the already released AVX2 extension. It's about time, as the continually increasing number of processor cores makes the need for technologies for faster thread synchronisation more and more urgent. Without such technologies, the processor will eventually be so busy with itself that it won't be able to get any real work done.
