Performance gain with Windows XP x64?

[Pete]

How much of a performance improvement can we expect on an AMD64 CPU running
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?

I read somewhere that it would be April.

No.

Interesting.
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.

32 bit apps running on a 64 bit CPU and OS will NOT run any faster. The
application has to be designed from the ground up to take advantage of 64
bit applications and run faster.

In order:

From zero to a lot. No.

April is what I've read.

Not just Nvidia, but they'll be a much greater incentive for them to improve
their drivers when the OS is actually out.

If you are talking about the same physical hardware with a different OS
probably true, but if you are switching from something like a Pentium 4
to an Opteron, you'll see a huge improvement .

I know many can't do this but I switched to 64 bit linux, where the os and
most of the apps have been compiled for 64 bit. As a bonus, I don't need
any resource hogging anti-virus programs.

So you are saying that Linux is immune to viruses? I know some virus
programmers that LOVE to hear people say that!

 

[f/fgeorge]

Probably not much.
Bill Gates probably can't be more specific at this point in time. The
Beta is progressing and as more "problems" are being found they are
being addressed by the folks at MS. When that process is done to the
satisfaction of MS, the program will be released.

I got an AMD64 and tried out windows-64 lots and tried out linux-64 lots,
and I've preferred linux. 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.

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...

As far as I know there are no Linux viruses in the wild as opposed to
100,000+ for windows. Besides, I never run in root so there is only so
much a virus or trojan could do if there was one. Also, in most cases you
have to actually make a .bin or shell script executable in order to run
it, so good luck to your friends who want to write virii for *.nix boxes.

A distro is a distro is a distro. I use Suse 9.2 but used to be a Mandrake
user. It's whatever you like. You have a CHOICE!

I put "linux virus" in a yahoo search, no quotes, and came up with
over 10 pages of links!

I kind of liked Knoppix when I ran it a couple of times.

You had to go back 3 years to find one?

No it was just first on the list.
