What does one do with a workstation, as opposed to an ordinary desktop,
that requires special boards and mulitple CPUs?
The term is being diluted these days, as people are calling things that
aren't workstations workstations, and we do indeed have improvements in
graphics and dual core deskstop chips on the way...
The main reason to get a workstation up until about 3 years ago was
graphics, graphics, and graphics. If you wanted to do CAD/CAM, video
production & editing, rendering, animation, medical imaging (still a
good use, get your CT-scan back a lot sooner), and much of scientific
computing. Much of this could be done of a regular computer, but some of
the medical imaging and scientific computing really did need 64 bits due
to the size of the datasets, and consumer level systems would choke
trying to display those models.
Outside of those fields, there was another reason, most computers were
just horribly slow. Most heavy users had dual PIII/Celeron systems in
the early days just to make their job tolerable. Most of these were
still hard drive bound, but they were fast enough. Most of these folks
don't have a dual cpu workstation anymore, they have a fast P4. This
need went away after we broke the 2Ghz mark for most users.
In large part, thanks to gamers being willing to pay a premium, consumer
level cards are catching up and the graphics power is there now. They
still don't have the optimizations that professional cards have, but the
raw power is there. These improvements (engines, processors) do get
passed along to the professional cards (the main difference between them
is software more often than not). Thanks to PCI-E, the power
requirements can now be met without having to have a workstation board
as well.
If you did mostly 2D work, you could make the jump a lot sooner. If you
needed 3D, you had to wait.
The other area workstations compete is on memory & storage systems. You
wont find a desktop that allows you to have more than 4GB of memory
easily, you can buy a workstation board that will let you have 8-16GB of
memory. The board will typically also have SCSI 320, and fast PCI-X
slots for additional SCSI raid controllers. Heaven forbid you have to
access the slow substorage system though, even with 320 it's still
thousands of times slower than main memory - even when you have to use
slower memory to get huge sizes it still works out in your favor.
I think they still have a place in people working with 3D models,
medical imaging, certain kinds of people working in animation and film.
Most of the software development people will probably end up turning to
distributed computing and dual core desktops to fill their needs, many
of the CAD people can already switch without pain provided they can get
enough memory and make intelligent motherboard decisions & select the
right graphics card. Heavy multitaskers like myself will wait on dual
cores to switch. I'm trying to hold out for a A64 4400...
