Funtoo Linux Subarches
This page provides an overview of Funtoo Linux subarches.
The amd64-piledriver subarch supports the AMD Piledriver microarchitecture produced by AMD from mid-2012 through 2015, which is the successor to the AMD bulldozer microarchitecture. Piledriver CPUs and APUs are available that use the FM2 socket. Piledriver CPUs use the AM3+ socket.
Server piledriver CPUs include Delhi (Opteron 3300-series), Seoul (Opteron 4300-series) and Abu Dhabi (Opteron 6300-series). 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 AMD steamroller microarchitecture, so amd64-piledriver stages can run on amd64-steamroller systems, and vice versa.
