All of the things that wouldn't work on the keyboard in Boot Camp worked just fine in the VM. Ctrl clicking acted as a right mouse button and obviously all of my function keys worked. Parallels' Workstation also comes with a set of tools that you can install in Windows that enable additional functionality such as a clipboard synchronization tool. The sync tool makes it so that anything you copy in one OS is available to be pasted in the other and vice versa, making the VM truly behave like just another application running in OS X.

By far the biggest drawback of the Parallels' Workstation VM is that the GPU makers currently don't support any sort of GPU virtualization, meaning all of the graphics are CPU rendered when running the VM. What this translates to are choppy animations and a laggy mouse pointer when you're navigating around Windows XP; of course, don't even think about running any 3D games. There is a Parallels video driver bundled that is supposed to improve things, but you still get nowhere near the performance of hardware accelerated 2D graphics.

Update: While finishing up this article Parallels released beta 3 of their Workstation VMM for OS X, one of its improvements happened to be an increase in performance and an improved mouse synchronization tool. The updates in beta 3 made the mouse lag virtually disappear, which was a huge improvement over beta 2. The animations in Windows XP were still quite laggy unfortunately, but without a real GPU driver that's not going to change. Needless to say, the improvements in beta 3 make Parallels' solution far more interesting as an alternative to Boot Camp.

The CPU performance was quite good, although the VM only allows Windows XP to access a single core of the Core Duo processor. In the end, the fact that the MacBook Pro has two cores works out very well for use with a VM manager as the VM can use one of the cores while your other core handles whatever you may be doing in your host OS.

Overall running Windows XP as a VM using Parallels' Workstation is extremely convenient, but personally the choppy animations are annoying enough to the point where I'd almost rather use Boot Camp. I think my preference would change depending on what I needed to be in Windows XP to do. Currently my only needs for Windows XP are when I want to play a game or need IE for a particular website; the former would require Boot Camp while the latter is better suited for a VM solution.

One thing is for sure, the VM route does hold a great deal of potential for the future. Once virtualized graphics and I/O are here, the days of being stuck with a single OS on a single platform will be long gone.

    The hardware issue mentioned have been or are being fixed.

    Apple has release silent revisions of the MacBook Pro. It is well documented on other sites such as Macrumors.com

    In fact, I believe Apple will give you a new revision if you complain about one of these problems.

    I know they are different benchmarks, but over at http://www.macworld.com/2006/04/firstlooks/xpbench...">MacWorld, they found that the MacBook Pro was faster at running Windows than three Windows-only PCs.

    I'm not going to editorialize here, just bringing this to your attention.

    Which pretty much drops macworld's benchmark credibility to zero. Actually, their credibility was already really low so its no big deal.

    Unless the benchmark was how fast it could burn a hole in your pants and sterilize your important parts.

    Sadly, even the most recent MacBook Pro's continue to suffer from the hardware problems you noticed. I've now had two units with the "whine," particularly when the laptop is running on battery power. The only way to stop it is to turn photobooth on and leave it on. Various hacks (magicnoisekiller in particular) help but really...

    Hey Anand!

    Thanks for an interesting review! Now, what was the video source codec and resolution in your H.264 encoding test? I've got a Mac zealot here saying he's got only 2 frames per second in similar H.264 encoding task. He also has Mac OS X 10.4.6 and Quicktime Pro 7.0.4. I wonder is you used source with resolution like 160 by 120 for that test??

    To other readers: take with a grain of salt Anand's view on running multiple apps simultaneously in XP. He says something like "uh oh we can't run multiple apps all the time on win coz win can't manage its RAM blah blah", but in fact if you disable XP swap AND if you stick 2 or 3 gigs or RAM in your mobo you'll get my experience of running dozens of apps open at the same time and even some games while at it (DOOM 3 + Matlab + Maya 7 + other little apps like VDub open at the same time is a no brainer on my XP). Stick 4 gigs and open even more, without loss of performance. In fact if you wanna get Mac OS X experience, just stuff your mobo with RAM and turn off swap, that's it, no need to spend $$$ on Mac to get this "experience" :-))

    One last minor correction - Anand tells you "anything more than 2GB of RAM on your PC is useless" but he does not know about /3GB switch (google up "/3GB switch") which again allowed me to run Matlab with THREE gigs or RAM consumed, not two.

    Just my 2 cents to debunk some myths that Mac zealots love to spread ;) Don't get caught in that stuff, read docs/mans and be smart.

    The source for my H.264 test was the Hoodwinked trailer from Apple's Quicktime trailers site.

    My comments about memory usage and Windows XP have nothing to do with the /3GB switch. The point I was trying to make is that Windows XP does not do a good job of caching to reduce disk accesses. Microsoft itself has admitted that there's lots of room for improvement, which is why you hear about all of the caching improvements that will be introduced in Vista.

    Take care,
    Anand

    BTW: if you don't think that anandtech knows about the /3GB switch you certainly haven't been here very long.

    Did Anand ever mention this switch in any of his reviews? Or anyone else besides him from AT staff? I've never seen it before. How about you? Would you provide me with a link or some other proof? I'd love to be corrected here, since AT guys should know about it, and I wish I were wrong stating the opposite, especially about Anand himself.

    As for the stability - I run Matlab with 3GB consumed routinely, it also loads some Maya 7 stuff internally via my own DLL and there's another Maya 7 hanging around to check results from Matlab quickly, and I never saw a slightest glitch. Of course YMMV but I heard too much "omg windoze is 2GB limited and mac is TrUe 64-bit WoNdEr" and I've got some experience with Matlab on both Mac OS X (no 64-bit matlab there) and WinXP (now this is true 64-bit product) to let Anand repeat that kind of sh.t. Mac guys are ok to say that, they live like this, so no big deal but not Anand please :-) So let's just say "please Anand be a bit more correct in some places and don't sound like a dumb Mac user", saying windows can't properly run a lot of apps at once and stuff like that.

    Speaking of Vista I've read somewhere on MSDN that a lot of XP 64 code is in there so it _should_ be as robust as XP 64 with regard to RAM handling. I'm sure after SP1 or SP2 it'll be absolutely rock solid :-)
  • kleinwl - Thursday, April 13, 2006 - link

    I've used the /3GB switch as well... however it can (and does) degrade the stability of your system (running fluent (a CFD program) on XP SP2). I wouldn't run around recommending the normal use of the /3GB switch. Some programs don't even support it (ie. Catia V15). Ultimately we upgraded to XP x64 (which came with it's own headachs).

    2.5GB seems to be the most that XP SP2 can really handle well.. everything else is a waste. OS X just does a better job handing large amounts of ram and not "losing" it with time.

    I am interested is seeing how VISTA will perform and if will be as good as OSX or XP x64 with ram... or something quite better (or worse).
