Talk:Puma (microarchitecture)

SoC

As far as I understand "Puma" refers to a microarchitecture for APUs, i.e. CPU & GPU & "uncore" (=Memory controller and some other logic). Yet it would be nice to document what other, additional componentry the SoC comprehends, i.e. USB2/3 ports, PCIe, because this is no longer found on the Motherboard but integrated on die in the chip.

Heterogeneous System Architecture and Zero-Copy

I am pretty sure that Steamroller-based Kaveri APUs support Heterogeneous System Architecture and Zero-Copy and so do the semi-custom APUs of the PlayStation 4 and the XBox One while the other Jaguar-based APU DO NOT SUPPORT HSA or Zero-Copy (though they would benefit the most because of their single-channel memory controllers). Did this change? Does Puma suport HSA and zero-copy mechanisms in hardware? User:ScotXW^t@lk 22:43, 1 May 2014 (UTC)

ExtremeTech claim Puma does NOT support HSA: http://www.extremetech.com/computing/181407-amd-launches-new-beema-mullins-socs-higher-performance-at-almost-low-enough-tdps User:ScotXW^t@lk 00:14, 2 May 2014 (UTC)
