There was a thread a while back, mentioning this precise thing. A pc running @64bits (amd's new chips) don't run as efficient or well because the software wasn't designed yet. Some KNOW IT ALL on Freerepublic told me otherwise, insisting they were right. Well, here it is, Read the article, you KNOW it All, and KISS MY AZZ!!!!!!!!!!!!!!!!!!!!!!! This post is dedicated to you "Know it alls". -1fastglock45

What?

[dts32041]

I have a 64 bit processor and a beta 64 bit OS but not software.

So I still use the 32 bit stuff.

64 bit machines can address 18 million tera-words, or 147 million terabytes.

the first 64-bit Windows desktop operating system, Windows XP Pro

What a load of crap.

Microsoft is actually the LAST mainstream provider of operating systems to hit 64bits.

Apple's 10.3 had some 64-bitness and Tiger has more of the system running in 64bit mode.

Sun's Solaris OS has been 64bit for many years and runs in 64bit mode on Opterons.

Linux has been 64bit for many years and runs in 64bit mode on Opterons as well.

If any OS can have twice as many bugs from running 64 bit than 32 bit, then Microsoft can do it! :-)

One of the neat things coming is a screen the thickness of card stock that can be rolled up inside a tube (see "Red Planet" with Val Kilmer for a glance) and virtual keyboards that sense where your fingers touch on any flat surface. Your entire PC could be the size of cigar tube and a pack of cards.

Actually, the AMD Athlon64 and Opterons do see a big bump in performance over Intels chips in running 32-bit apps due to the onboard memory controller. Not just because they are 64-bit.

There is a performance hit on running 32-bit apps on a 64-bit OS as it has to run in Compatibility Mode. Running in Long Mode or full on 64-bit mode would not have this hit.

NVidia and ATI have stepped up and released full on optimized drivers for graphics apps. The Linux community has already been optimizing apps and OS's for 64-bit registers. MS is a bit behind, but the release of XP-64 is a step in the right direction.

Releasing Longhorn, optimized for 64-bit and multi-core, will be the biggest thing to hit the computing desktop since Win95. Assuming they avoid their usual practice of code bloat.

Either way, AMD rocks.

decaf,

deep breath and relax.

You are going to pop a blood vessel.

Well, at least I know how to spell "ass".

All modern day computers and compilers are built around relocatable code, they have base registers and offset registers.

The code is written, all (or most) 32 bit code should run fine on a 64 bit processor.. if the hardware engineers know what the hey they're doing.

And judging from the things I take apart and put back together, comon sense is not so common in engineers..

Big Blue has been working on this type of stuff for what?, like three decades?
