Intel hyper threading

Intel has recognized that its CPUs without SMT Simultaneous Multithreading, which the former chip giant calls HTT Hyper-Threading Technology, have a competitive disadvantage and is bringing the technology back.

As Intel CEO Lip-Bu Tan now had to admit in the context of the announcement of the quarterly results, the Santa Clara-based company has realized that its CPUs without SMT ("Simultaneous Multithreading"), which was traded at the former chip giant under the name Intel HTT ("Hyper-Threading Technology") and was abandoned with the processors from the Core Ultra 200S series ("Arrow Lake"), have competitive disadvantages and is therefore bringing the technology back.

How to enable hyper-threading

Without the technology, which leads to the doubling of the threads of a CPU, the company is currently far too poorly positioned and has to correct this circumstance with the upcoming processor series. Intel is thus making a comparatively rapid turnaround, since HT / SMT was only removed from the feature set with the hybrid Core Ultra of the first and second generations, aka Meteor Lake, Arrow Lake and Lunar Lake. In the desktop, the Core-i-14000 recently offered the doubling of the threads of performance cores, while the small energy-saving e-cores do not support Intel HTT anyway. According to Intel's CEO Tan, competitiveness has suffered as a result.

To support this, we're reintroducing simultaneous multithreading. Abandoning SMT has put us at a competitive disadvantage. Returning to SMT will help us narrow the performance gap. - Lip-Bu Tan, CEO of Intel -

However, the plan cannot be implemented so quickly or implemented in already advanced CPU designs, so it cannot be assumed that the upcoming 7th generation server processors, aka Xeon 7 ("Diamond Rapids"), will be able to offer hyper-threading.
