"Apple sent a letter to the DoD saying it will assure
production of the 1.8 GHz PWRficient processor for three to five years, said one source who saw the letter but asked not to be named. The letter suggests
Apple will explore selling the designs to a third party after that time."

So, what we know about the CPU:
- it is a SoC
- it's Power Isa 2.04 or greater
- it's 64 bit (with 32bit fallback/compatible mode)
- it has enough serdes lines for PCIe x16
- it runs @ 1,8Ghz
- it dissipates >20W in full load & there's CPU cooler mounting holes on board
- it's dual core
- faster than anyting AOS4 has run on so far (per single core)
- the SoC has GPIO lines
- it "seems" to have two DDR2 bus (not officially confirmed)
- what else
So far only PA6T match with all that. (including known new y2010 production chips)
SMP, 64bit AOS4 .... sounds like Hyperion MAP to me.
(even though initially AOS4 runs in 32bit mode & single core)
PA6T specs...
- two DDR2-1066Mhz memory controllers
- Up to 16GB per channel (32GB max RAM)
- 2MB of L2 cache (900Mhz, IIRC) visible for both cores
- 2*64kb L1 Data cache
- 2*64kb L1 Instruction cache
- server-class reliability
- Dual integer execution units per core
- Full floating-point unit per core
- Full VMX unit per core
- Supports multiple, different operating systems simultaneously on each core
- 25W worst-case power dissipation
- 65nm CMOS technology
etc...
It is a huge jump from anything AOS4 has run on so far!
For example with PPC440ep we have no L2 and "only" 32k of L1 cache (32k i+32k d). On x1000 it seems that we have huge caches and superb fast RAM!
PA6T has more cache RAM than many classic Amigas had any RAM when they shipped...
I hope that we see PA6T kind of chip also on the low end ASAP.
IMHO: well worth 1500€ as a PPC HW
and... I started to wonder if there is already a military buyer for PPC+xcore combination ... -> key to PA6T availability??
