For HPC loads Fujitsu builds specialized [[SPARC64 VI#HPC specialized processors .28fx.29|SPARC64 fx]] processors  with a new instruction extensions set, called HPC-ACE (High Performance Computing – Arithmetic Computational Extensions).

Fujitsu's [[K computer]] ranked {{Numero|1}} in the [[TOP500]] June 2011 and November 2011 lists. It combines 88,128 SPARC64 [[SPARC64 VI#SPARC64 VIIIfx|VIIIfx]] CPUs, each with eight cores, for a total of 705,024 cores—almost twice as many as any other system in the [[TOP500]] at that time. The K Computer was more powerful than the next five systems on the list combined, and had the highest performance-to-power ratio of any supercomputer system.<ref name="top500-2011-06" /> It also ranked {{Numero|6}} in the [[Green500]] June 2011 list, with a score of 824.56 MFLOPS/W.<ref name="green500-2011-06" />  In the November 2012 release of [[TOP500]], the K computer ranked {{Numero|3}}, using by far the most power of the top three.<ref name="top500-2012-11" />  It ranked {{Numero|85}} on the corresponding [[Green500]] release.<ref name="green500-2012-11" /> Newer HPC processors, [[SPARC64 VI#SPARC64 IXfx|IXfx]] and [[SPARC64 VI#SPARC64 XIfx|XIfx]], were included in recent [[PRIMEHPC FX10]] and FX100 supercomputers.

[[Tianhe-2]] ([[TOP500]] {{Numero|1}} as of November 2014<ref name="top500-2014-11" />) has a number of nodes with [[FeiTeng|Galaxy FT-1500]] [[OpenSPARC]]-based processors developed in China. However, those processors did not contribute to the [[LINPACK]] score.<ref name="nvidia-fastest-tianhe-1" /><ref name=cw>{{cite news|url=https://www.computerworld.com/s/article/9194799/U.S._says_China_building_entirely_indigenous_supercomputer_|title=U.S. says China building 'entirely indigenous' supercomputer|last=Thibodeau|first=Patrick|publisher=[[Computerworld]]|date=November 4, 2010|access-date=August 28, 2017|archive-date=October 11, 2012|archive-url=https://web.archive.org/web/20121011154327/http://www.computerworld.com/s/article/9194799/U.S._says_China_building_entirely_indigenous_supercomputer_|url-status=live}}</ref>
