XP 64 bit..

Først og fremmest vil man kunne bruge mere end 4 GB ram.
Det er max for de nuværende 32 bit processorer.
Faktisk vil man kunne benytte helt op til 18 milliarder gigabytes.

"Current CPUs for PCs have eight registers that hold 32 bits each, which imposes two limits on them. First, they can't access more than 4 gigabytes of RAM. That's because each byte (a byte is eight bits, treated as one chunk of data) of RAM has a unique address number that needs to fit into one register. Since each bit has at most two possible values—0 or 1—a 32-bit PC can handle 232 addresses, which multiplies out to 4 gigabytes of RAM. Upgrading to 64-bit registers lets the chip access 264 bytes—that's 18 billion gigabytes, more RAM than exists on the entire planet."

Second, on a 32-bit machine, numbers that run longer than 32 bits (for example, fussy values of pi) require lots of juggling in order to perform calculations. That slows down computer-aided engineering and animation, corporate data mining, and other number-crunching applications. It adds bugs, too, as these overlong numbers are shuffled among registers. Upping the register size to 64 bits is like widening the freeway, which is why high-end servers and professional graphics workstations moved to 64-bit processors years ago.

On our desktops, though, most of us haven't had a pressing need for the upgrade. A 64-bit CPU won't make Microsoft Office run any faster, and it doesn't speed up e-mail or Web surfing. It won't help anyone this side of Warren Buffett with the family spreadsheets. That's why Intel decided not to develop a 64-bit Pentium, putting its efforts instead into a 64-bit chip called Itanium meant to run specialized applications in corporate backrooms rather than consumer software on home PCs.

AMD is pushing the 64-bit label in hopes that, like Microsoft shrugging off the Internet fad a decade ago, Intel has woefully misjudged the demands of its customers. There's also the hope that computer buyers will treat 64-bit computers like they do computers with more gigahertz—they don't know what it is, but they assume that more is better.

But right now, there are only two obvious uses for a 64-bit PC at home: games and video. For video, doubling the CPU's word size means the billions of bits in a movie can be encoded and decoded more efficiently, enabling higher resolutions and faster editing.

Games work differently. A separate graphics chip renders the videolike images, while the CPU usually calculates the behavior, position, and motion of each object in the game—whether it's the physics of a bouncing ball or the sneaky moves of a robot adversary. Game programmers say the problem with Pentiums isn't that they have 32-bit registers, but that they have only eight of them. The new Athlon tackles that, too, sporting 16 double-wide registers. Rebuilt 64-bit editions of games will be able to use those extra registers to calculate more realistic motion and faster-thinking opponents.

So, the buyer's guide is easy. If you absolutely must get a new PC now and want the fastest available, AMD has the season's hot chip. Keep in mind, however, that its raw speed has nothing to do with the fact that its word length is 64 bits. The era of "cinematic computing" won't kick in until there's software written for the chip's 64-bit capabilities and its extra set of registers. If you have to buy a PC now, you might as well buy a 64-bit one, so you're not disappointed when Microsoft (which owns Slate) puts out its 64-bit Windows XP sometime next year, or when the game-makers flood next year's holiday shopping season with 64-bit titles.

But if you can wait, there's no rush. Save your money for Christmas 2004. By then, not only will there be software that shows off your computer's eye-popping capacity, but also—and just as important—your $3,000 will buy a much more powerful Athlon

18 milliarder gigabytes.. more RAM than exists on the entire planet!

Shit nogle ram-klodser der skal til!

Tænk også på prisen.
Jeg synes mine 512 MB var dyre nok. *GYYS*
Der skal garanteret også et par sokler til?

Gad vide hvor store harddiskene er når folk en gang bruger 18 milliarder gigabytes ram?

hehehe

Ja, og nogle monster bundkort der fylder en foldboldbane eller noget...

Ja sådan ville det nok være, hvis man skulle benytte nutidens teknologi.
Men for få år siden var 1 GB ram jo helt uhørt, ja det var utopi.

Men på det tidspunkt bruger vi nok ram moduler med en kapacitet omkring en petabyte.

EDIT: Fandt lige en smart tabel
Men max vil stadig være 18 exabyte, det er altså meget.

Ja, kan godt se at DET er meget vigtigt for os lige pt... .... Men på den anden side, så ved man jo aldrig hvad den næste Windows-version vil sluge ...

Hey ... Så har nVidia jo en fordel der. Så må de hive fat i nogle af de gamle maskiner der lavede grafikkort før i tiden og så bare sætte dem til at lave bundkort istedet for. *G*

Hvor meget er Peta/Exa byte? Har jeg aldrig hørt før..

1 PetaByte (PB) = 1 Million GB

1 ExaByte (EB) = 1 Milliard GB

Hvis man går ud fra at 1 GB = 1000 MB .... Selvom det så jo er 1024 MB ...

Men nemmere at regne med 1000 da HDD-producenterne jo gør det ...

Kig her:
http://www.pcsndreams.com/Pages/Articles/Megabytes.htm
http://www.t1shopper.com/tools/calculate/

En Petabyte er 1000 Terabyte, og en Exabyte er 1000 Petabyte.
Og en Exabyte er en milliard Gigabytes, derfor må 18 Exabytes være 18 milliarder Gigabytes.

Her er en lille tabel:
bit bit 0 or 1
byte B 8 bits
kibibit Kibit 1024 bits
kilobit kbit 1000 bits
kibibyte (binary) KiB 1024 bytes
kilobyte (decimal) kB 1000 bytes
megabit Mbit 1000 kilobits
mebibyte (binary) MiB 1024 kibibytes
megabyte (decimal) MB 1000 kilobytes
gigabit Gbit 1000 megabits
gibibyte (binary) GiB 1024 mebibytes
gigabyte (decimal) GB 1000 megabytes
terabit Tbit 1000 gigabits
tebibyte (binary) TiB 1024 gibibytes
terabyte (decimal) TB 1000 gigabytes
petabit Pbit 1000 terabits
pebibyte (binary) PiB 1024 tebibytes
petabyte (decimal) PB 1000 terabytes
exabit Ebit 1000 petabits
exbibyte (binary) EiB 1024 pebibytes
exabyte (decimal) EB 1000 petabytes
zettabit Zbit 1000 exabits
zettabibyte (binary) ZiB 1024 exabibytes
zettabyte (decimal) ZB 1000 exabytes
yottabit Ybit 1000 zettabits
yottabibyte (binary) YiB 1024 zettabibytes
yottabyte (decimal) YB 1000 zettabytes
brontobit Bbit 1000 yottabits
brontobibyte (binary) BiB 1024 yottabibytes
brontobyte (decimal) BB 1000 yottabytes

EDIT: Har lige tilføjet de sidste.

Rimelig vilderen det der..

Jep, kan du så få proppet noget mere ram i din maskine.
Det er ikke der skoen trykker ihvertfald.

Harddisk mener du vel ... ... Hvis du snakker om EB / PB

Sad lige og overvejede hvorfor jeg skiftede min P4 2,6 ud med en A64 3000+... Selvfølgelig pga. 64 bit teknologien!

Men hvor meget kommer man til at mærke til 64 bit XP når det engang kommer?

Bliver programmerne hurtigere eller hvad er det i det hele taget der kommer til at køre hurtigere?

Tja, jeg skiftede fordi jeg mente det var blæret. Skiftede tilbage til P4, da jeg fandt ud af, at det ikke hang sådan sammen.

Øhh nej, når nu hans A64 kan addressere 18 exabyte, så skal han da ikke bare køre med 512 MB.
