If microsoft make 64 bit system,what can we do.
who know how long do until microsoft hava 64 bit system?

They already have one, XP64.

32 bit are not enough :) ?

More bits is more better! Give me all your bits, this is a break-in!



..32 bits is plenty good though...

32bits isn't that good if you need more than 4gb of RAM, but we're about 1 or 2 years away from that in personal computers :P

Bah, addressing is just a minor thing for most users who aren't running a server. Imagine moving 64 bits at a time. It's like having MMX without MMX registers.

mov rax, 0ffffffffffffffffh
and rax, 0102030405060708h

Graphics, sound, everything will move that much faster. Scotty, maximum warp and set phasers on slaughter !

and rax, 0102030405060708h

Yeah! and mov r15, 0ffffffffffffffffh will be possible ;)

does anybody have some more information about the amd64? some things like datasheets with the amount of contents like "Intel Architecture Software Developer's Manual"? i'd like to know everything about their internals

i found em right after i asked :D
but thanks anyway.

Here's an open source assembler for the "Itanium? Architecture" from our friends at intel:

what are the differences between the Intel Itanium and AMD opteron?

Amd x86-64 architecture is "next" generation of current x86-32 CPUs.
It has full harware support of all P4 instructions, plus new registers, commands, etc.
Itanium, IMHO, is CPU "from another world". It uses emulation of x86. So no asm, just C :)
Howewer Intel is developing "secret" alternative for Operton, known as "Yawmill", just "in case"

Itanium is in compatible with the present IA32/x86-32 ("standard" 32-bit) CPUs, Opteron (x86-64) is howerve compatible, it's kinda like the 80386 -- from 16 bit to 32-bit twice (32 to 64) :)

but are the 64 bit instructions the same between the Itanium and opteron?
i mean, will the assembler for the Itanium produce code that will work on the opteron?
Posted on 2003-08-26 06:39:43 by jack

No. the Itaium is IIRC using the IA64 architecture - incompatible with both IA-32 (x86-32) and AA-64 (x86-64).
Stuipd "misstake" by Intel IMO, they should have kept them compatible.

Personally I think its about time the slate was wiped clean. If it wasn't for the price I'd buy an Itanium before AMD64 anyday.

64 bits...
I think this will be a waste of memory in most purposes because you will have to store your data with qword alignment.
Even 32 bits are really much.

So I hope they'll make an optional 32 and 16 bit (fast) adressing.

And if you want faster graphics and sound you propably should use the GPU and SPU of your graphics- and soundcard.:grin:

Why don't they jump immediately to 128bits or more if its so much faster?;)

Hmm, you can't survive to day with out a propper gfx card... (The CPU deals with all the central processing (things like instructing other devices and Processing Units), the GPU "only" processes graphics).
Why have 128-bit colors? You wont be able to see all the 2^128 colors... (as for sound, MP3s with bitrates at 190-200 are already used for music )
