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, this subarch is instruction-compatible with its successor, the, so amd64-piledriver stages can run on amd64-steamroller systems, and vice versa.
The amd64-steamroller subarch supports the AMD steamroller microarchitecture, produced from early 2014. It is the successor to the AMD Piledriver microarchitecture. Steamroller APUs are available that use the FM2+ socket and FP3 socket (mobile.)
Desktop steamroller APUs include the Kaveri A-Series APUs, also available in mobile versions. Server steamroller APUs include the Berlin APUs, which are not yet released.
Amd64-steamroller subarches are instruction-compatible with amd64-piledriver, but add new instructions over amd64-bulldozer.
