Amigaone/OS4, but in it's absence, a bit of education to keep the mind alert
sounds good to me <G>
It is actually highly relevant to the A1's future outside the immediate user
base. Assuming you use a good PSU, and taking Alan's 'best' efficiency of
about 75%, the approx 80 W that a G3 saves against an
equivalent-delivered-end-user-power x86 means that you actually save around
110W, or around 1000KWHr pa. on 24/7 running. Using round numbers, an
average energy cost in Europe is around 0.10 euro/KWhr that is
100euro/cpu/year saving. However virtually all of this 110W turns into heat,
and in a server environment needs taking away. The reduction in a/c running
cost (maintenance, electricity etc) effectively doubles the saving to around
200euro/yr/cpu, and in a a decent sized server farm (say 5000 servers) that
equates to savings of 1m euro pa over the x86 equivalent - not a figure
that any server farm CFO would sneeze at.
Ther are further savings in this server farm environment as well. The lower
heat generation in the box means that you need less circulating air, so some
less fan capacity but mainly smaller sized rack boxes, maybe as much as down
from 4-U to 1-U or perhaps only half of that. That means that you only need
half to a quarter as much real estate for your server farm, and obviously a
smaller investment in a/c plant. And since most major backbone access
points tend to be in cities these savings real estate costs can be very
All of that means higher volumes for the A1 hardware and - if you can wait
that long - prices low enough to penetrate the mass market (with OS4) again.
At least that's the plan.
Oh yeah, and we are currently (from Wednesday last) shipping the A1-XE in
volume, first to the dealers, then to the developers who ordered the SE way
back but decided to change to the XE, then to board purchasers by order
date, then to system purchasers by order date. We expect to get the backlog
cleared by the end of the month, but only if people avoid the temptation to
ring up and ask how their order is doing - all that does is slow things up
for everybody. We're all working flat out ATM - what else do you think I'm
doing in the office this sunny bank holiday Friday!

2.6 kernal is better multi-processor support.
I know this isn't that important to a Lightwave renderfarm (I belive
they work on images independently, rather than 1000-CPUs rendering 1
image at a time). However, it is good news "down the road."
