It seems to me every few months Asus will come out with a new mobo. Do they
think after a few months they have sold all the ones of a particular model
they are are going to sale? Alot of the times the changes don't really seem
that significant and the board has just been modified only slightly to the
extent that a hyphen and 1 or 2 more letters are added to the board's model
number.
Even car manufacturers give it a year before they start over, but sometimes
even a year seems to soon.
The typical process with a modern motherboard manufacturer is to
design an OMNIBUS bare motherboard for a given processor family and MB
chip-set and then program the surface mount equipment to just load and
auto-probe-test selected configurations, based on the manufacturer's
market research and desired price-points. The theme is to as closely
as possible match production to demand sweet-spots while producing
as few variants of the base unpopulated motherboards as possible.
Configuring the machine-placement setup for adding or omitting various
components on a given raw motherboard is a trivial operation,
completed in a couple of days for programming for each variant.
Setting up the auto-probe-test for a specific variant might take just
a little longer. However, doing the complete setup for a brand new
raw-ECB layout might take a major re-configuration of the production
and test line. That is why you see limited "families" of
motherboards, but with lots of variants. If some of the variants do
not meet you specific requirements, blame the manufacturer's marketing
reearch teams.
If you examine a typical modern motherboard very closely you will
probably see some empty pad-areas --- they are for other variants,
maybe even OEM versions not available in the retail motherboard chain.
However, technology changes are happening faster in all areas these
days.... witness the current activities at CES, mind-boggling.....
A particular motherboard "family" today may not last more than a year.
Many of such 'family' changes are forced by rapid component
obsolesence. For example, the 915 and 925 chipsets are now obsolete
after about a year of production, incompatible with dual-core -
unsuccessful chipsets and CPUs now have a very short life indeed at
Intel........... The motherboard manufacturers have to dance to both
the component-suppliers tunes and the customers pulling on the
puppet-strings.
