The [[NEC SX-2]], a [[supercomputer]] developed by [[NEC]] in 1983, achieved gigaFLOPS (GFLOPS) performance with 1.3 [[billion]] FLOPS.<ref>{{Cite web |title=【NEC】 SX-1, SX-2 |url=https://museum.ipsj.or.jp/en/computer/super/0008.html |access-date=2025-08-25 |website=IPSJ Computer Museum |publisher=[[Information Processing Society of Japan]]}}</ref> In 1994, the [[NEC SX-4]] was the world's first supercomputer to achieve teraFLOPS (TFLOPS) performance with 1 [[trillion]] FLOPS.<ref>{{Cite web |title=【NEC】SX-4 |url=https://museum.ipsj.or.jp/en/computer/super/0018.html |access-date=2025-08-25 |website=IPSJ Computer Museum |publisher=[[Information Processing Society of Japan]]}}</ref>

In June 1997, [[Intel]]'s [[ASCI Red]] was the secondworld's first computer to achieve one teraFLOPS and beyond. Sandia director Bill Camp said that ASCI Red had the best reliability of any supercomputer ever built, and "was supercomputing's high-water mark in longevity, price, and performance".<ref name="jacobsequity.com">{{cite web |title=Sandia's ASCI Red, world's first teraflop supercomputer, is decommissioned |url=http://www.jacobsequity.com/ASCI%20Red%20Supercomputer.pdf |access-date=November 17, 2011 |archive-url=https://web.archive.org/web/20101105131112/http://www.jacobsequity.com/ASCI%20Red%20Supercomputer.pdf |archive-date=November 5, 2010 }}</ref>

The[[NEC]]'s [[NEC SX-9|SX-9]] supercomputer was the world's first [[vector processor]] to exceed 100&nbsp;gigaFLOPS per single core.

In June 2006, a new computer was announced by Japanese research institute [[RIKEN]], the [[MDGRAPE-3]]. The computer's performance tops out at one petaFLOPS, almost two times faster than the Blue Gene/L, but MDGRAPE-3 is not a general purpose computer, which is why it does not appear in the [[TOP500|Top500.org]] list. It has special-purpose [[pipeline (computing)|pipelines]] for simulating molecular dynamics.
