On November 15, 2011, Intel demonstrated a single x86-based processor, code-named "Knights Corner", sustaining more than a teraFLOPS on a wide range of [[DGEMM]] operations. Intel emphasized during the demonstration that this was a sustained teraFLOPS (not "raw teraFLOPS" used by others to get higher but less meaningful numbers), and that it was the first general purpose processor to ever cross a teraFLOPS.<ref>{{cite web|url=http://www.tomshardware.com/news/intel-knights-corner-mic-co-processor,14002.html |title=Intel's Knights Corner: 50+ Core 22nm Co-processor|access-date=November 16, 2011|date=November 16, 2011}}</ref><ref>{{cite web |url=http://www.eetimes.com/electronics-news/4230654/Intel-unveils-1-TFLOP-s-Knight-s-Corner |title=Intel unveils 1 TFLOP/s Knight's Corner |access-date=November 16, 2011 }}</ref>
