with only a 650 watt psu.
Unless I plan to run some render farm or suchlike I'd never touch a system needing that kinda power.
Well, it's not that the T2 will ever consume that much power, even with 2 x 18 core CPUs. It is because the current T2 mainboards need 2x 8-Pin EPS12V power connectors - which are only found on the bigger specced PSUs.
In case they sell enough of the current units they are planning an ATX-based mainboard (w. only one CPU socket), which I guess would only need one 8-Pin 8-Pin EPS12V power connector. However even the "low end" 4-core/16-threads POWER9 got a TDP of 90 watts. Don't know how much they consume idle.
Yes, but 90 watts is the ragged edge of what can be cooled fanless, and even then it requires a stupid sized heatsink.
Oh, and I received an answer to an inquiry about about the smaller board from Raptor.
They wouldn't confirm an ATX size, only saying that it would be "smaller" than the Talos II boards.
That could be ATX, MATX, who knows?
Still, I like that Power 9 is bi-endian and has a hypervisor.
It should allow combining big and little endian sessions, something that is beyond X64.
Oh, and not to take a "dump" on anyone's dreams, but the feedback I'm getting is that emulation of the PPC on an X64 by QEMU is actually pretty poor.
So running PPC MorphOS application on an X64 platform doesn't look practical.
Recompilation will probably be the only practical recourse.
We have already seen emulation of X64 on Power 9 systems and it looks fairly competent.
And it should allow KVM based concurrent big endian PPC sessions to run alongside little endian sessions including those that emulate X64.
One is relatively cheap, X64. The other is relatively expensive, Power 9.
There are pros and cons to each.
But the developers have already indicated their intentions.
