Performance gain with Windows XP x64?
Windows XP x64? Should we expect any performance gain on 32-bit applications/games running on a 64-bit OS like x64? Also, anyone have any more specific idea than "first half of 2005" as to when Windows XP x64 will be released?

32-bit applications won't be any faster at all. Applications that are designed for 64 bit platforms will see a lot more speed-up compared to 32 bit if they make use of 64-bit numbers, for instance a chess program that has 64 squares should be a lot faster, I'm hoping anyway... I'm planning on writing a chess program and compiling the same program on 64-bit linux and 32 bit windows and playing them off against each other to see who wins.... Also it depends a lot on how well the app is designed. For instance, a 64-bit program can *address* lots more than 2GB of memory. But it doesn't mean to say that your computer's actually *got* that much physical memory... I can imagine some programmers thinking that "Having 64-bit pointers means you can use as much memory as you like". Evidently not true! However, I'm definitely thinking get a 64-bit computer *sooner* rather than later, you don't want to be one of the last people on earth left with a 32-bit one... just think, if you suddenly found out that you were the last person on earth to still have a 16-bit computer, would you have the time and money to get a 32-bit one *by tomorrow*? I know I wouldn't...

I supposed there will be a benefit from using 64bit drivers, but games' performance is not so impressive - it is worse in 64bit WXP than in 32bit. Maybe the nVidia 64bit drivers are very badly optimised.

application has to be designed from the ground up to take advantage of 64 bit applications and run faster. -- Show quoteHide quoteDaveW "Pete" <p***@hello.com> wrote in message news:37e0foF5atu57U1@individual.net... > How much of a performance improvement can we expect on an AMD64 CPU > running Windows XP x64?

If you are talking about the same physical hardware with a different OSprobably true, but if you are switching from something like a Pentium 4 to an Opteron, you'll see a huge improvement :-). -- >>==>> The *Best* political site <URL:http://www.vote-smart.org/> >>==+ email: Tom.Hors***@worldnet.att.net icbm: Delray Beach, FL |<URL:http://home.att.net/~Tom.Horsley> Free Software and Politics <<==+ "Pete" <p***@hello.com> wrote in message In order:news:37e0foF5atu57U1@individual.net... > How much of a performance improvement can we expect on an AMD64 CPU > running Windows XP x64?

As a bonus, I don't need any resource hogging anti-virus programs. On Wed, 16 Feb 2005 06:01:45 -0500, jeff arch wrote:

Windows XP64 certainly the beta version is incapable of doing windows update, which although it's excused slightly because it's a beta, incapability of updating itself makes it pretty darn pointless. FC2 x86_64 can do yum update to its heart's content....also it isn't only a 360 day trial version. Not to say linux-64 doesn't have problems, for instance it doesn't like onboard graphics chipsets, my VIA K8M800 would not work with it at all, however nvidia graphics cards just work straight out of the box and are even better with perfect animation if you install the drivers off the nvidia site, which is easy to do. And also no linux distribution is worth bothering with other than fedora. On Wed, 16 Feb 2005 18:32:39 +0000, bonj wrote:
