» Despite big wins, AMD still not getting much respect on corporate
desktops | Between the Lines | ZDNet.com

Interesting but not at all surprising. The main issue, as has so
often been the case, has little to do with the processors and
everything to do with the chipsets.
First problem: Until recently there were no AMD chipsets with
integrated graphics. While this might not seem like an issue for us
home users who tend to prefer external graphics, *ALL* corporate
desktop systems use them. Doing so not only reduces costs but it also
simplifies support of these systems, a key factor for corporate
desktops. If you look at the new Athlon64/Sempron based system that
HP offers in their corporate desktop line (the dx5150) they are based
on the relatively new ATI Radeon Xpress 200 chipset using ATI's
integrated graphics.
For those who haven't seen it, this HP dx5150 system is a pretty damn
kick-ass system for a corporate desktop.. better performance and
feature set (integrated dual-head video is rather nifty!) than the
much more expensive Intel-based dc7100 also mentioned this article.
The only real downside, and the reason (IMO) why it's classed as a
mid-range 5000 series instead of a high-end 7000 series business
desktop is that it uses a different BIOS than HP's standard. This
means that some of the nifty remote manageability tools might not work
right (I haven't tested this one way or the other, so I can't say for
sure what, if anything, breaks). It's also missing a few optional
security feature add-ons available for the 7000-series, ie the hood
lock and the TPM/TCPA module, though these are more design decisions
on HP's part rather than any failing of the processor or chipset (the
Intel-based 5000 series systems also lack these features).
Second problem: Different chipset vendors equals a whole can of worms
for corporate desktops. The article hits on this, and actually it's
one thing that won AMD some fans a while back. The H&R block case
they mentioned was specifically for the HP d315 and it's follow-up
d325 systems. These both used AthlonXP processors and nVidia chipset
(the nForce 220 in the case of the d315 and the nForce2 on the d325).
AMD and nVidia trumpeted the H&R Block as a real win for themselves
because the company was able to use an identical image on both of
these systems, something that is damn near impossible to do normally.
Obviously Intel learned from this and is working on stabilizing their
drivers sufficiently that they can do the same sort of thing.
Unfortunately though that just wasn't going to be an option going
forward, and switching your image from one Intel chipset to another
Intel chipset is easier than going from an nVidia chipset to an ATI
one. With the two Intel images you can usually use all of the same
drivers but just re-install them while building your image. With
nVidia vs. ATI you need a whole separate set of drivers from the
ground up.
