The '''amd64-piledriver''' subarch supports the [[Wikipedia:Piledriver (microarchitecture)|AMD Piledriver microarchitecture]] produced by AMD from mid-2012 through 2015, which is the successor to the [[Wikipedia:Bulldozer (microarchitecture)|AMD bulldozer microarchitecture]].
Codenames for desktop Desktop piledriver CPU and APUs include '''Vishera''' (FX-8350, FX-8370), '''Trinity ''' [[Wikipedia:List_of_AMD_accelerated_processing_unit_microprocessors#Virgo:_.22Trinity.22_.282012.2C_32_nm.29|Trinity A-series APUs]] ''' (A6-5400K, A10-5800K) and '''[[Wikipedia:|Richland A-series APUs]]'''.Codenames for server Server piledriver CPUs include '''ZurichDelhi''' (Opteron 3300-series), '''Seoul''' (Opteron 4300-series) and '''Abu Dhabi''' (Opteron 32006300-series). [[Wikipedia:Opteron#Opteron_.2832_nm_SOI.29_-_Piledriver_Microarchitecture|More information here]].
Piledriver adds several new instructions over bulldozer, so AMD bulldozer systems cannot run amd64-piledriver-optimized stages. However, subarch is instruction-compatible with its successor, the [[Wikipedia:Steamroller (microarchitecture)|AMD steamroller microarchitecture]], so amd64-piledriver stages can run on amd64-steamroller systems, and vice versa.
Piledriver CPUs and APUs are available that use the [[Wikipedia:FM2 Socket|FM2 socket]]. Piledriver CPUs use the [[Wikipedia:Socket_AM3+|AM3+ socket]].
