... from which I take it you didn't comprehend Joachim's point.
Time to market is a way to say how quickly a code or computing platform
(software side) can be put into production. At least this is what we
are told.
Time to market has *nothing* whatsoever to do with what you are talking
about in this context. Others feel free to jump in and
correct/dispute/etc. this.

See above.

Hmmm ... I used to read what you wrote (note the past tense) though I
skim it for ... er ... nuggets ... these days.

This is either the most insulting or amusing thing I've read in a really
long time. Years.
I'll take it as amusing.
Yes Vincent. We, who push our gear that hits more than 5 GB/s sustained
to and from spinning rust, in a single box, with less than 50 disks
required to get there ... we who push our flash arrays and SSD arrays
that hit millions of IOPs ...
Yes Vincent, we are ignorant of performance. We obviously don't get or
understand performance. We have no interest in it.
(the preceding should be read aloud with a voice positively dripping in
sarcasm)
I am laughing now. No, really. Thats laughter you hear.

I bought (with my own cash) Opteron and Xeon. Clearspeed, FGPAs, GPUS etc.
And you?
Won't buy bulldozer for us for a while. Looks like it needs some
performance tweaks, and the compilers have to do a better job for it.

Er ... I don't drink soda (sound of an opaque metaphor shattering).

Ahh ... an obtuse path to discuss time to market as a function of cost.
So if your development cost requires you pay expensive programmers for 6
months working on very expensive hardware with very expensive tools for
an application that will have a usable lifetime of 3-6 months (or
whatever window is relevant) ...
... versus ...
you pay your very expensive programmers for 1-2 weeks working on less
expensive hardware with well designed and inexpensive tools for an
application that will have a usable lifetime of 3-6 months (or whatever
window is relevant)
... which of these will
a) cost less to build/test/deploy
b) have a longer time in market to make you money?
And your expensive programmers get to work on the next task, therefore
increasing your ability to have a collection of tools actively engaged
on the market.
Seriously, if you don't get why this matters, well ...

Oh. My.
Vincent ... um ...
How do I say this ...
Why don't you google me, with the phrase ... I dunno ... "AMD
whitepaper opteron" or similar things. Here's one you might find:
http://developer.amd.com/assets/Computational_Chemistry_Paper.pdf
I can send you others in PDF form if you like.
If you read some of the white papers we wrote for them, you might even
find where they got the APU expression from ...
Heh.
