64-bit Systems Being Sold With 32-bit Vista

Is this some kind of scam or what?
That would mean that any machine with a 32 bit os is a scam as both AMD and Intel produce almost entirely 64 bit CPUs and they have done this for a few years. [EDIT]I think the scam is selling a system with less than 4GB of memory (unless it is an i7 where memory is expensive). I mean 4 GB of high quality DDR2 is $50 USA. I guarantee they are paying less than that and I also guarantee they are using lower quality as I know dell and HP use lesser quality memory than corsair. There is where the scam is. However they have to pay for support somehow.. [/EDIT]

For sure! Until something like 3 or 4 years ago, RAM size in PCs was following Moore's law. And now it has come to a stop for PCs carrying 32 bits OSes. And as you point out, this is unnecessarily restrictive since processors are 64 bits.

That is kind of a lame response! If you want to criticize someone you should at least provide one reason.

App/driver compatibility is still lower for 64bit OSes than for 32bit versions. Installing 64bit when it's not needed would simply add to the number of hissyfits being thrown about how evil MS/Vista are because they don't work with LegacyPosNumberFiftyFiveThousandNineHundredAndEighyThree. Meanwhile for normal consumer apps there's little to no benefit. PS as long as you have a vista64 disk (any version) you can upgrade your retail box using it and the provided media key for free. Since you really should put a clean install on any OEM PC anyway to get rid of the crapware....

I wasn't aware that both versions come on the same media. Maybe they do. If so that is good and my rant is dispelled. What about systems that come with no media, but include a Restore partition? Can someone verify whether this is true?

idk, I think I can install 32bit Vista with my 64bit Disk so maybe it is just the default choice.

Most of this sig is for Google, not ego.What is this "disk" you speak of? I haven't seen a retail system come with a DVD or CD of the OS in years.* I've had to use the menu to create recovery disks from the system. In which case, I've got only the version which was installed, not both 32- and 64-bit. * my purchases have been HP, maybe other vendors are more generous?

Are you saying that the fact that the O/S can process instructions 64-bits at a time rather than 32-bits at a time is no advantage? I would agree with you that many apps are 32-bit; however, 64-bit processing by the OS must improve performance. Would it not?

Vista32 (all versions) and Vista64 (all versions) are two separate disks. If you already have a vista64 disk (any version) you can install vista64 (same version as the v32 install) on a machine that came with vista32 preinstalled using the license key that the machine game with. A full retail boxed copy contains both DVDs. OEM/System builder packages only contain one (the other costs $10 from MS), I don't know what the upgrade version has. If noone else replies with the answer to this I can check when I get home, I ordered a cheap upgrade package recently but haven't opened the box.

I have an Asus laptop, it came with a Disk. My disk contains both 32 and 64 bit Vista Ultimate.

Unless you're doing something with numbers too large to fit in a 32bit space there's little to no benefit, and having to use 64bit pointers results in increased memory usage and more frequent cache misses (extra space taken by the pointers). The net result is that unless you have an app that is designed to benefit from the larger word size or have more than ~3gb of system memory there will not be any meaningful real world gains. IIRC the bigger pointers effect typically dominates to a 1 or 2% penalty.

32-bit vs. 64-bit refers to the size of addresses. It's mainly '64-bit addressing', not '64-bit processing'. What exactly do you mean with '64-bit processing'? If it's RAM access - that's done a whole cache line at once (64 BYTE or so, no matter what the OS is). Yes, 64-bit has more (and larger) registers. Some programs compiled for 64-bit run faster than their 32-bit counterparts. But on the other hand, pointers are twice as large. They take more memory -> less data fits into the processor cache. Some programs run faster in 32-bit mode. And most software is still 32-bit -> Windows will need to have both 32-bit and 64-bit versions of the system libraries loaded at once. If the machine is low on RAM, this will hurt the performance.

Most system builders provide an OEM version of Windows. The OEM versions are either 32-bit or 64-bit. If you want the choice, you still have to purchase a retail version of Windows (which comes with both versions on the same disc).

I'm not criticizing *you*, just your rant. :) I'm running 64bit windows as the host os for my development machine (all my work is done in 32bit virtual machines) and I can assure you there is very little reason to want a 64bit os other than to go beyond the 4gb memory limitation. It's far harder to find apps that support it properly, speed for apps is entirely the same with some very limited exceptions, many apps don't like to be installed on 64bit windows and act up on it. I think the hardware vendors are doing their customers a favor. On the other hand I know of no hardware vendor that doesn't offer the *option* of os so I'm not sure why it's a problem, you just specify the OS you want in the end anyway.

This has been probably occurring for some time now, but I just became aware of the fact that in Canada, new 64-bit systems are being sold with the 32-bit version of Vista. Is this some kind of scam or what? It seems that if you buy a system with less than 4 Gig they install 32-bit Vista on it. So because I buy a system with less than 4 Gig they choose to reduce the processing power I get. Well, that's really nice!!! NOT!!! Why this is totally ridiculous: If I bought 1 Gig of RAM several months down the road then I have to bare the cost of doing an upgrade to 64-bit Vista assuming I want the extra speed (which I would want regardless). As long as the system vendors are ripping people off like this I certainly will never buy a system from them. I usually build my own. The only reason for considering an off the shelf system is simply to get the O/S with the system for less than what it would be if I built the system and bought the O/S separately.

Chill. My 64 bit processing power is making my laptop overheat while I type this on my other, 32 bit, single core, laptop that's still as cool as steel.

I know of several vendors that do not offer the option: HP laptops and desktops that are sold from Futureshop, Best Buy, London Drugs, Walmart and probably others. These guys sell it as is, with no possibility of change. This is not an issue for me, but it might be for other users. Maybe I am belaboring this point as the performance gain may not be that significant.

There is something missing here that I don't understand. Starting with the Pentium Pro (32-bit CPU), Intel processors have been able to access more than 4 Gigs of RAM. This is handled via PAE (Physical Address Extension) mode (see Intel CPU docs for more info). This being the case, why did Intel start developing 64-bit processors if there is no performance advantage? Seems like a rather expensive road to go down if what you say is true.

I don't think you are quite correct here as the Pentium Pro (32-bit) has the capability of addressing up to 64 Gig using PAE (Physical Address Extension) mode. That implies that Intel created 64-bit processors for another reason. If it has nothing (or little) to do with performance, then what might that reason be?

This maybe the reason that Intel has introduced the use of 3 cache levels, increased cache sizes, and incorporated the memory addressing unit inside the CPU (or at least I think this last point was a recent change).

This could be the reason why they choose not to install the 64-bit OS on machines with less than 4 Gig.

Unless you're doing something very specific and very high end that involves tremendous amounts of hard core math or data shuffling in memory it's actually slower for several reasons pointed out (although I think they forgot to mention WOW emulation). I wouldn't run it if I didn't have to for my virtual development system to cater to the memory requirements. I think 64bit os's are basically best reserved for situations where you have a single computer dedicated primarily to a single task that has been *proven* to be faster on 64bit os and was designed for it. As a general purpose os, 64 bit is *not* the way to go.

Because PAE is a fugly kludge. If you did any programming back in the dos/win16 era, it's a resurrection of the segmented memory model and requires significantly more effort to implement than standard x86. Native x64 code works just like the 32 bit version and if well written is fairly painless to port (If you were unwise enough to hardcode pointer, etc sizes into your app it gets painful).
