OK i read into it a little and came across the news of it being 64bit instead of 32bit so i though. WOW! sounds great.

Then as I was starting to think about getting one (£700 with the board) I was thinking isn't all the software at the moment for the 32 bit. So I was thinking it would be useless.

Anyway long story short. I dont get it . lol

Mind explaining it to me?

Thanks
vivi

Well - depends on your point of view. The 64-bit AMD processor (and not the Intel ones) have an emulation layer, which according to their figures adds around 10% processing time. But the lost 10% is made up by having a fast(er) processor...

well depends actually... in Windows XP 32bit then yeah the new processor (if you have SP1a) is automatically detected and the emulator is used.
Whereas in Windows XP 64Bit or Media Center 2004, well it is doing it naturally (hense why they found the 8-15% speed decrease).

Your still talking 2.4x the speed of a similar spec processor.
I.E Intel Pentium4 2.2Ghz or AMD AhtlonXP 2.2Ghz would be pushing around 2,200 on CPUMark

whereas the AMD Athlon64 50 2.2 will push 4,600 and if you get the FX-51 2.2 then your looking at a further speed within 3D Intensive Tasks. (particularly Shader Games)

As this speed is STILL a good 20% above the Pentium4 3.2 HT, it is very safe to say ... this is quite frankly the best there is for gaming and other processor intensive tasks.

I would advise getting and AMD-64 when Windows XP 64-bit comes out...

WindowsXP 64Bit is already out nick, only you've gotta get it mail order from Microsoft. Not sure why.
Longhorn / WindowsNx will have it built-in though. Still the speed increase is far better.

i mean the Athlon64 FX-48 1.8Ghz is the equivilant speed of a Pentium4 3.0Ghz, that in itself is enough for me to want more of these puppies.

and divide, Shader are games standards now ... it's not longer a question of "will they be", this is now just like TnL. It's a standard and the more power you have to calculate them quicker the better it'll be in the long run.

Haven't seen it in stores, and I must admit I haven't got actively looking for it (no point for me). Wish I had waited for getting my computer now - oh well!

Actually I think M$ just delayed the 64-bit version. There have been some rumors that it has to do with intel, trying to get their own 64bit processor to the market.

Oh well, I'd say that the 64bit cpu's are a mostly a waste of money at the moment. By the time you can really take advantage of the 64-bit mode, the price on those cpu's has dropped a lot (cos it's a new product) plus there will be faster models around.

And from the test's I've seen, the 64bit cpus are actually bit slower (because of the emulation) than the similar 32bit models.. :\ Only in few cases the 64bit processors beat the rest.

you mean WindowsXP 64bit which has been out for over 2years now? o_O

Athlon64 and Opterons pin setup is now stable, they're out and there will be no configuration changes.

No, not the one for Itanium Processors, but this one

WindowsXP 64Bit covers PPC64 and IA64 and they recently released SP2 which included X86-64

both my x86-64 based systems are running it fine and much much faster now. I mean even in 32bit WindowsXP they were running faster than my Dual Itainium2 Processors (which i thought was pretty amazing in itself), but with 64bit mode there just isn't a comparison in speeds. It's like trying to compare a 586 with a Pentium Mmx.

well anyways, that document actually is talking about the Longhorn Support

Perhaps that is why it says Windows XP about 10 times and longhorn none.

Quote: "The beta version of Windows XP 64-Bit Edition for 64-Bit Extended Systems is available to MSDN® subscribers, and a final release is expected to be available in the first half of 2004."


So longhorn is going to be released in the first half of 2004 is it?
Bill Gates doesn't think so, but what would he know?

Perhaps you should change the spec in your sig.
You have 2 x86-64 systems and a dual itanium2 system but you have a computer with such a low spec?

Well i don't know about the Extended System, all i know is that Service Pack 2 released back in July for Windows XP 64Bit fully supports the Opteron and Athlon64 FX processors.
Before that they showed up as AthlonXP 3200+ with an unknown family stepping.

and why would i put the specs to all 5 of my systems within my signature?
i simply put the one i actually play games on. the rest of my systems are PURE working machines, no games, no unprotected networking, specifically setup with firewire lan so they can work realtime and be used as render farms.

Current specs of each of my systems;
Athlon64 FX-51 (oc 2.8ghz ~4.0ghz) | 1.5gb | FX5950 ultra 52.20 | Dx 9.10 | WXP-64 (Alienware's Aurora)

Quad Opteron 420 (oc 2.0ghz ~16ghz total) | 2gb onboard 8gb PCI | SLi QuatroFX 3000G 512mb | Dx 9.02 | WS-03, Solaris

Dual Itainium2 800 8mb Cache Edition 3.0Ghz | 3.0gb | Radeon9800XT 256mb Cat4.0.D | Dx 9.02 | WS-03, Red Hat 9.0

G4 2.0ghz | 1gb | FX5700 ultra 52.10 | Optimised Ref Lib (ORL) 6.3 | MacOSX

plus this machine which is my regular
i don't particularly need alot of power on this machine itself for development because i use Maya6, Photoshop8, Max6 ... all of which are capable of running as Network Nodes from another machine, so all this one has to do is actually display what is being used.
