Say you produce a cpu now within 2 weeks. it's 200 watt. it's 1 gflop
and it's $100 production price
including R&D overhead, including everything except shipping to
Good idea to sell?
time to market matters for simple software engineering - not for
stuff that has to perform ok?

Yeah i bet some dudes want to know at which age i wrote my first
and and at which age i wrote my first trading application - but i won't.
Had you read what i posted - which you obviously never do - it would
be pretty obvious to you i had.
Also shows how total ignorant you are about performance. but let me
ask you next 3 questions:
a) when are you gonna buy a bulldozer cpu from your own cash? If so
why? And if not why not?
b) you drink of course a cola from a local supermarket isn't it, so
no pepsi nor coca cola - price matters most isn't it?
expensive wines? Time to market huh?
c) in 2003 AMD was first to market a x64 cpu, intel following with
core2 some years later. Did you buy this yourself or advice others to
- i bet like everyone on this list you get daily requests on what to
buy isn't it, so be honest
- what did you advice in 2003 and 2004 to those surrounding you?
