Could 64-bit Windows finally be taking off?

by Ina Fried

If you build it, it appears they will come, eventually.

Such is the case with 64-bit computing. Advanced Micro Devices back in 2003, hoping the fact that it was there and didn't cost extra would convince consumers.

"Our industry, right now, is hungry for another round of innovation," AMD chief Hector Ruiz told the crowd at the San Francisco launch in September 2003. Not that hungry, apparently.

Of course, the hardware wasn't much use without a 64-bit operating system. After several fits and starts, Microsoft finally released a 64-bit version of Windows XP in the fall of 2005.

"64-bit versions of Windows will begin to find their way into high-end gaming notebooks, which increasingly are being used as high-end notebook workstations as opposed to strictly gaming systems."
--Richard Shim, analyst, IDC

Still, several factors have of 64-bit computing, long after the operating system was available. First of all, there wasn't a lot of need for it. The primary advantage of 64-bit computing is the ability to use more than 4GB of RAM, and until very recently most PC buyers had little need for that much memory. Also, to connect to a computer running 64-bit Windows, printers, scanners, and other peripherals need to have a .

But it appears the benefits are starting to outweigh the drawbacks.

In a blog post this week, Microsoft's Chris Flores noted that 20 percent of new Windows Vista PCs in the U.S. that connected to Windows Update in June were running a 64-bit version of the OS, compared with 3 percent of new computers in March.

"Put more simply, usage of 64-bit Windows Vista is growing much more rapidly than 32-bit," he said. "Based on current trends, this growth will accelerate as the retail channel shifts to supplying a rapidly increasing assortment of 64-bit desktops and laptops."

The trend is also evident by looking at the kinds of systems being sold at retailers. In its circular this Sunday most of the desktops and half of the dozen notebook models being advertised by Office Depot had the 64-bit version of Windows pre-installed.

The mix was similar in Circuit City's advertisement, with nearly all of the desktops and many of the notebooks running 64-bit Windows

Gateway, for example, is shifting to an entirely 64-bit Windows lineup on its desktops, starting with the back-to-school shopping season.

It's a dramatic shift even from last quarter, in which only about 5 percent of its total desktop and notebook models had a 64-bit OS installed. For the third quarter, 95 percent of desktop models and 30 percent of notebook systems will have a 64-bit OS.

Among the factors leading to the shift are the fact that 64-bit machines, unlike their 32-bit brethren, can directly address more than 4GB of memory. Also, more 64-bit software is finally coming to market, as evidenced by last week's release of a 64-bit optimized version of Adobe Lightroom.

IDC analyst Richard Shim said he expects even more computers will start shipping preloaded with 64-bit Windows toward the end of this year. "64-bit versions of Windows will begin to find their way into high-end gaming notebooks, which increasingly are being used as high-end notebook workstations as opposed to strictly gaming systems," he said.

The original problem with 64 bit windows was poor device driver support. With the release of Vista the playing field has been more or less leveled by poor device driver support on both the 32 and 64 bit platforms. With programs demanding more and more RAM, and 32 bit windows stuck at 3.?? gigs of usable RAM going to 64 bit usually doesn't give any WORSE of an experience, as it did with XP.

XP64 was horrific! No drivers, memory leaks, frequent BSOD. I am running Vista 64 and absolutely love it. I have 8gb of ram in my box, 2 9800gtx's in SLI with an AMD 6000+ black edition overclocked. This system is rock solid with only one blue screen in the year+ that I have had it. It absolutely flies through applications. It eats SETI@Home blocks for breakfast and can still run games with that in the background. A lot of people think 8gb of ram is an overkill, but I've had the SETI@home thing going on, with Firefox open with about 6 tabs, photoshop open, and playing COD4. I know that's not practical, but it's kinda cool :)
by Imalittleteapot August 4, 2008 7:25 AM PDT
8 gig is overkill unless you're using virtualization to run multiple operating systems at the same time, but I never do that. You probably never do that either, but at least you won't have to upgrade for a while. Now, you shouldn't be getting BSODs on XP or Vista. If you're getting a lot BSODs in XP and a few in Vista double check to see if your hardware has any driver updates you can download. Since you're running two 9800gtx's I'd recommend double checking your temps to see if that thing isn't running a little hot. You may want to do a mem test too.

@imalittleteapot: 8GB is a very cozy amount of RAM for 3D/CG apps if you have the CPU 'oomph to back it up with. :)
by bobby_bolan12 August 16, 2008 4:38 AM PDT
32 bit Vista has great driver support. It was dodgy in the early days, but now Vista supports anything and everything I have thrown at it.

I have 3 gig of RAM and it is often going unused (usually at least 1 gig free), so I doubt the need for more than 3gig is going to force people to 64 bit until Windows 7.
by i_am_still_wade August 4, 2008 6:07 AM PDT
Another thing to consider is that games are starting to approach the memory limits of what a 32-bit OS can offer. Another Vista 64-bit requires a lot more memory, it is worth having. Some 64-bit applications can do things in about 1/5th the time of 32-bit applications. Someone actually timed how long the loads where in the 32-bit and 64-bit Half-Life 2 games, and the 64-bit version was significantly faster.

Vista has designed to be 64-bit. I can tell you that Vista with 4 GB+ of memory is a dream. At 4 GB, everything is faster than XP.

You're completely right. From my perspective, gamers were one of the biggest drivers over the last year for the 64-bit version of Vista. Now, this is a combination of ever advancing game requirements and Vista being such a memory hog.

4GB seems to be the sweet spot, but with each advancing year, memory is a huge factor leading to better pc performance. In this way, you need a 64-bit OS to address all that memory, in effect making it all usable. As normal consumer applications like Office, Sharepoint, Quicken, Quickbooks, Photoshop advance in requirements, the amount of people adopting 64-bit OSs will also continue to rise.
by bobby_bolan12 August 16, 2008 4:40 AM PDT
FWIW Vista is faster than XP regardless of the amount of RAM in my experience. My previous PC with 1GB ran faster after upgrading to Vista.

64-bit is the next step obviously, but the question is *when*.
by Jonathan August 4, 2008 6:22 AM PDT
What no Apple zealots bashing Windows? Wow they must all still be asleep. :-P

Seriously though. This fall I'm going to be building a new system. The price of RAM has gotten to a point that 8GB isn't that far fetched an option. So Vista 64 will probably be in my near future.

PS- Any word on SP2 for Vista?!? Yah yah I know SP1 only came out a few months ago...still.

Don't worry, I'm still awake. And yes, Microsoft still sucks the big one.
by bobby_bolan12 August 16, 2008 4:41 AM PDT
Is there a need for SP2? Vista with SP1 is remarkably stable, fast, compatible.

I doubt there will be another SP until at least mid 2009. I don't really think there are enough issues with Vista now to justify a service pack.
by RompStar_420 August 4, 2008 7:07 AM PDT
I been using Win XP 64bit for over 3 years, it's better and seems more stable than the 32bit version, but still lacks drivers to this day for my printer, overall it is ok.

My Mac beats it any day, hahahaha

BTW: I am about to sell my Win XP workstation, I rarely use it, takes up space.

I think it sucks they sold 64 bit systems with 32 bit Vista in the first place. If you have a 64 bit chip and there's a 64 bit OS available then they should install that instead. With XP64 it was a different story, but with Vista the 64 bit version is better. The OEMs lied in their advertising when selling 64 bit systems. Some OEMs shipped computers with 64 bit chips but with components that only had 32 bit drivers. You still couldn't use a 64 bit OS but they lead you to believe you could. It wasn't that big of deal except for the advertising. In the flyers they put a big 64 right next to the computer, especially many AMD systems. That was the major problem in my opinion. They used it as an advertising gimmick when technically it was a false claim. Total scam because they knew most people wouldn't be that upset about it. That's why I'm glad I built my own system and planned ahead so it can run XP32, Vista 32, Vista 64, Linux 32, and Linux 64 bit. Yeah, it took a bit to pick that hardware out, but it was worth it.


Thank God you can find more 64 bit drivers for Vista then you could then.
You should be able to switch your 32 bit Vista license for a 64 bit Vista license for free or at a discount. Shouldn't have to pay full price twice to take full advantage of your machines chip and ram use, especially if you want to upgrade your ram. It wasn't that long ago you couldn't find Vista 64 preinstalled on the shelf. You basically had to take 32 bit. Then buy the 64 bit version on your own. When you buy a computer all features should be able to function 100 percent out of the box. Imagine getting a computer only to find out the sound card won't work until you buy another $200 operating system. I know it isn't quite the same thing, but it's just the honest thing to do.

Unless I'm mistaken, you can get Windows Vista 64 bit DVDs for free if you own Windows Vista 32 bit. Just write Microsoft and ask for them. You have to send back your 32 bit DVDs though.

That's cool, but I already own both for two different systems. I was unaware of this though. Microsoft should advertise that instead of Mojave.

May I please stay in touch with you. You are more knowlegable than I. I have a 3+ year old laptop( I custom ordered it from xtremenotebooks.com)the I use for DV production. It runs XP home. I am happy with the $1500 software(video production- DV Rack, Ultra 2, and editing programs- Liquid) and do not need to spend $$ for upgrade for new OS. Basicly, I wish to keep what I have for the future.
I got an A+ tech cert in the mid 90's, so I know just enough to be dangerous.
I just replaced the hard drive with probably the last 7200 RPM(necessary for the software I use) IDE notebook drive I could find on the internet, so the laptop hopefully wil be good for another 3 yrs. Please stay in touch, so I may seek your advice in the future, keeping hardware and software expenses to a minimum.

I tried and tried to get Linux (SUSE) to install on my AMD 64 motherboard but it kept crashing and the only 64 bit Os that could isntall was SUSE 9.x
Version 10.x kept telling me it was not a 64bit based hardware.
weird. my bios settings were correct.
Microsoft used to offer for a short time the 64 bit of XP for free and just use your current key for your 32bit OS. WIsh they would offer the 64version of XP again.

If it makes you feel any better the boot graphics on the old 64 bit version of Ubuntu causes my video card to have a spastic attack and blank out until the login comes up, but not on 32 bit. Then on shutdown it does it again except the computer never shuts down it just goes BEEP BEEP BEEP BEEP!!! It scared the crap out of me. However, it will work fine if I use nosplash text boot and Fedora also works fine. I'm pretty sure the newest version doesn't do this, but I haven't tried that yet. Something about the 64 bit version of the boot graphics program not cooperating with the 8000 line of nvidia cards. I don't know. That's Linux for you.

Re: "Could 64-bit Windows finally be taking off?" Huh! How about awaiting for the arrival of the "64-bit CASSINI" (Code-Base OS/2) = "64-bit Windows + The Explosion of the Ariane 5"

"On June 4, 1996 an unmanned Ariane 5 rocket launched by the European Space Agency exploded just forty seconds after its lift-off from Kourou, French Guiana. Ariane explosion The rocket was on its first voyage, after a decade of development costing $7 billion. The destroyed rocket and its cargo were valued at $500 million. A board of inquiry investigated the causes of the explosion and in two weeks issued a report. It turned out that the cause of the failure was a software error in the inertial reference system. Specifically a 64 bit floating point number relating to the horizontal velocity of the rocket with respect to the platform was converted to a 16 bit signed integer. The number was larger than 32,767, the largest integer storeable in a 16 bit signed integer, and thus the conversion failed...."

Yep 64 bit is taking off, I've built more 64bit OS's this year being either Server 2003 or Vista 64.
As for Cr'Apple - well mac lovers can say what they like. Not many apple users are system builders anyway. Apple are lagging big time when it comes to 64bit operating environment....their latest product Iphone doesn't support 64bit. Quicktime doesn't work on a 64 bit OS very well, not to mention itunes etc. If they don't do something about it soon they will be nothing more than legacy systems or playing catchup with technology which M$ have already been developing for a few years.

Apple's OS has been 64 bit for a while. There are only two versions of apple's os.. the "main" version and the server version (both 64 bit). You're comment regarding Quicktime not working well in a 64 bit environment speaks volumes about how little you must know...
by Jonathan August 4, 2008 1:29 PM PDT
I'm no fanboi. Hell people on Macrumors hate my sorry butt for stating the truth over there. However Leopard is 64-bit. Tiger had sections that was 64-bit. And why in the name of all that is good and holy would you want 64-bit on the iTurd or any other smartphone for that matter? Pointless would be an understatement. Heck even Windows Mobile isn't even remotely close to being 64-bit either. iTunes/Quicktime works perfecly fine on a Mac. As for iTunes\Quicktime on a PC....*shrugs* It works about as well as Microsoft apps on a Mac. No company puts a ton of effort into putting out polished software on a competitors's system. And even then 64-bit Windows as the article noted is 20%. Why would you go out of your way to support that few users. And if you want to talk flawless transition XP 64 was NOT pretty. 10.4 & 10.5 other then being buggy as hell out the gate. They are pretty much 100% compatable with software. It took MS a second attempt at Windows (Vista) to get a 64-bit OS compatable with 32-bit software.

It's amusing that this news article turns up just as I'm trying to persuade Dell UK to send me a 64-bit Vista Business OEM Install DVD (for free) so I can install it on my currently 32-bit Vista Business Vostro 400 desktop. Sadly, Dell are no different from other OEMs w.r.t. 64-bit Windows: 1) They don't mention the "bitness" of the Windows they ship [it's almost inevitably 32-bit, but I think they should state it], 2) They should be very clear that ordering 4GB RAM with the default Windows install is pointless because you can only use 3.25GB of it (you might even argue that 4GB RAM shouldn't be offered *at all* with 32-bit Windows, but that's up to debate) and 3) they should offer 64-bit versions of Windows as alternatives when the machine is configured.

Dell's official line on 64-bit Windows seems to be "we can't support it fully, particularly the drivers", but if they're offering 4GB RAM on machines, I think this something that they *should* support!

Sorry bud, but you are in the minority. If there was a selection to go 64-bit when you buy a new system it would just confuse the hell out of the norms who aren't geeks and wouldn't know a bit from a byte.
As for offering 4GB. Show me a way to put 3.25GB in there in pairs (Because of DDR.) that doesn't cost a metric crap ton of money and I'd be willing to cut you some slack. As it stands someone is not going to drop 2 1GB sticks of ram and then go out and install 2 256MB sticks. Hell do they even make DDR3 in 256 sticks? Better yet if they do It would probably cost Dell a metric crap ton because only a handful of neurotic, anal-retentive people would be willing to buy such things. Meanwhile the memory sits on the shelf.
by alegr August 4, 2008 5:23 PM PDT
Jonathan,

The PCIe devices are mapped to addresses between 3 and 4 GB. 1 GB of RAM is remapped over 4 GB.

32-bit Vista cannot use that 1 GB of RAM above 4GB address, this is why it's left with only 3 GB accessible. 64 bit Vista can use all of it.
by Imalittleteapot August 4, 2008 8:38 PM PDT
Well, if you install SP1 it'll at least say you have 4 gig of ram. It will still have a memory hole in it that I think is actually being used just not how it's supposed to be used, but whatever. However, watch out because Dell sold motherboards that don't actually support 4 gigs of ram at all even on the 64 bit version of Vista but said the computers could use 4 gig of ram. This is part of the scam I'm talking about. It would suck to find out you had one of these mobos. As soon as they start selling computers with 8 gigs of ram and 16 gigs of ram preinstalled with Vista 64 or Windows 7 I'm just going to go ahead and get a new system to finally, once and for all, get rid of this 32 bit crap.
by RompStar_420 August 4, 2008 8:54 AM PDT
For AMD64, try Ubuntu 64-bit, that's what I use and it works very well. There are still some programs and applications that were not compiled for 64bit, but overall it works all really well, I run a server off of Ubuntu 64bit.

Works like a dream.

Well this Mac lover will say something. Apple has been using 64bit chips since 2003, starting with the PowerMac G5. Today, all current Macs sold are operating on 64bit tech. the previous MacOS had some 64bit programing and the current OS is fully 64bit compliant (as well as seamlessly 32bit compliant meaning no new fancy drivers are needed during a 32 to 64 conversion period). I can't speak for Apple's software running on Windows as I have no experience in that arena but to say that Apple is lagging big time in 64bit is misleading.

by Penguinisto August 4, 2008 5:30 PM PDT
@catch23: Leopard is fully 64-bit with a 32-bit compatibility layer. Tiger had a dual 32/64-bit personality. Panther had 64-bit extensions.

In short, while PC builders were acting confused and working in fits and starts towards 64-bit computing for the consumer market, Apple has been easing into it very nicely.

I've been using Vista 64 bit for a while now. Definitely do not want to run Vista 64 bit with anything less than 2gb ram though if you want performance. Just remember when 16-bit windows was prevalent, and 32-bit was coming out. It was soooooo hard to find 32-bit apps back then. It wasn't until Microsoft embraced 32-bit in their OS that people took notice, instead of adding 32-bit support when needed in WFW 3.11.

However, Microsoft is not the first company to embrace 64-bit OS/Apps, Solaris has been utilizing 64-bit apps since 1993-1994 but only on their hardware could you use it. I'm just surprised that we've had 64-bit Processors since 2003 and it takes 5 years for the consumers to take notice. That's a bit too slow if you ask me. It took about the same time for 32-bit apps/OS to catch on as well.

ozidigga your priceless calling Mac OS X "legacy", the fact is that you probably never uses a Mac and for that matter even Linux. if actual bothered to do a bit of research you relies all 3 OS have there advantages and disadvantages. i hate how people make assumptions on things they have no idea about.

Mac OS X supported 64BIT Unix Applications since Tiger (2005), 64 BIT Cocoa Applications since Leopard(2007). plus the one version of Mac OS X Leopard supports 32BIT/64BIT Intel & 32BIT/64BIT PowerPC Applications side by side on the same system (i.e. MacPro). i think too many people make a big deal of 64bit. i had a 64bit system since first PowerMac G5 came out. and all my systems since are 64BIT. besides running a Database at full tilt, Playing Games, Editing HD Video or ProTools. don't get me wrong Quicktime and iTunes should of been in 64 bit for both Mac OS X / Windows. but i guess apple too busy, we have to wait for Snow Leopard

Support for 64-bit on the Mac has been more hype than reality. Even with Leopard today, the truth is very few applications on the Mac are actually running in 64-bit mode.

But what's sad is, even with Leopard, the KERNEL itself remains 32-bit!!! Mac developers would like to fool you into thinking that Mac's "transition" to 64-bit was a non-event. The truth is, there was never a transition. Leopard's kernel remains 32-bit because moving to 64-bit would break all the drivers (like it did for XP64 and Vista.)

Worse though is Apple's decision to abandon support for 64-bit Carbon applications. This means that Carbon apps (e.g., just about any Adobe application, any application built on Qt, etc.) can never run 64-bit natively on MacOS unless completely rewritten or use slow IPC hacks to wrap 64-bit components.

I also see many comments about "my mac has been 64-bit since the G5 days." Wrong!! Again, hype vs. reality. Even today with Leopard, many major systems are 64-bit only when running on an Intel processor!!! Example would be Leopard's Java and any app which depends on it.

Lastly software publishers today must ship Universal Binaries targeting both PPC and Intel, which already bloats Mac binaries by a factor of 2. Because Tiger can't run *ANY* 64-bit GUI application, to support 64-bit publishers would have to develop, test & ship (at least) 32-bit PPC, 32-bit Intel and 64-bit Intel versions... needless to say the vast majority of publishers aren't going to do so, the ROI for that just doesn't make sense.

I just bought a new HP computer and sure enough it had Vista 64 pre-installed. Great computer and the software seems to run just fine, but I was unable to install a couple of my USB devices (audio devices). I went on the manufacturer's website and they only had Vista x32 drivers available, even after 6 months of people posting in their forums, BEGGING them to release Vista x64 drivers. So unfortunately this computer is useless for what I bought it for (audio editing) until the drivers are released. I'm sure a lot of other people are running into similar situations!
