@@ -4,7 +4,7 @@ In the late 1980s [[!wikipedia IBM]] developed a POWER family of processors.
 This evolved to a specification known as the POWER ISA. In 2019 IBM made the POWER ISA [[!wikipedia Open_source]], to be looked after by the existing [[!wikipedia OpenPOWER_Foundation]]. Here is a longer history of [[!wikipedia IBM_POWER_microprocessors]]. These IBM proprietary processors 
 happen to implement what is now known as the POWER ISA. The names
 POWER8, POWER9, POWER10 etc. are product designations equivalent to Intel
-i5, i7, i9 etc. and are frequently conflated with versions of the POWER ISA (v2.08, v3.0, v3.1).

 Libre-SOC is basing its [[Simple-V Vectorisation|sv]] CPU extensions on POWER ISA, because it wants to be able to specify a machine that can be completely trusted, and because POWER, thanks to IBM's involvement,
 is designed for high performance.
