Ono NEC v Earth simulare ma specialne vektorove procesory pre superpocitace a tie nie su dostupne pre trh ale su vyrabane na kusy a preto maju vyssi vykon, to je logicke, ale vdaka tomu su aj drahsie 4000 USD/kus oproti 1500 USD/kus u Opteron-u.
>A ještě pro fanatický AMDčkáře ... kdopak podle vás pomohl dodělat >Opterona a kdopak jim prodal většinu důležitých technologií?! Ano, bylo >to IBM, takže Opteroni mají jenom to, co již Power5 má delší dobu!
IBM robila len technologiu SOI nie CPU design

AMD K5, 1996 - Mike Johnson AMD/NexGen K6, 1997 - Greg Favor - AMD started internal K6 work as an extension of the K5 base, but this was discarded in favor of buying NexGen and using their Nx686 design relabelled as K6
- see The Anatomy of a High-Performance Microprocessor (K6-2 3D-Now! case study)
- AMD K6-2, 1998
- AMD K6-III, 1999
AMD Athlon (K7), 1999 - Dirk Meyer (Dir. Engr.), Fred Weber, ... x86-64 architecture - Kevin McGrath and Dave Christie AMD Opteron (K8), 2003 - Jim Keller and then Fred Weber - Jim Keller left and the initial K8 design was canceled
- Fred Weber led the project to revise the K7 into a 64-bit core
mimochodoam Jim Keller robil aj Prescott-a u Intel-u, cize chvala Bohu, ze odisiel
aj ked to nie je ziadny hej pockaj
Alpha - Dick Sites and Rich Witek
implementations
21064 (EV4), 1992 - Rich Witek (lead)
21164 (EV5), 1995 - John Edmondson (lead during design), Pete Bannon, and Jim Keller (lead during advanced development)
21264 (EV6), 1998 - Jim Keller (lead)
ale na Ritch-a Witek-a , odborneho poradcu AMD- on riadi a smeruje vyvoj a sefa vyvoja u AMD Greg-a Hoepnner-a alebo sefa CPU divizie AMD Dereck-a(Dirk-a) Meyer-a nema

as part of a lawsuit settlement between DEC and Intel, Intel acquired StrongARM and the DEC design team left
