P4 with EMT64

[ethen]

I know in japan they already have P4 with EMT64 extention, anyone know when US will have them?

I saw a post that they are selling them in England too. I think they want to liquidate all of their current 32 bit chips first.

We are talking Billions in lost profit, if the 64 take off with tone of 32's in stock.

Lost profits? Then why are AMD and Intel still bringing out new 32bit chips?

Because 64 Bit is not a requirement for modern processing and its not benificial for users and even for ethusiasts such as ourselves. No reason it at all, the basic user does not give a crap if the processor can do 64 Bit or not, it just matters if it is fast and optimised. 64 Bit is not optimised and so far is no faster then 32 Bit. As a matter of fact benchmarks show that its slower in XP 64 bit eddtion from what I have seen. At the current time, we are not limited by the CPU's resgister size like we was when the 4 bit in the nibbler and untill then, the benifits will be nill.

I am saying, 32 bit processors have a couple years of life in them.

yeah, longhorn is still gonna be in 32 bit, that will give another 4-6 years for the next one, but i was just wondering since i'm shopping for intel chip now (my job require me to use Intel c++ compiler and AMD wont work well)

are you sure that amd's won't work well? it should work just fine.. for common instruction sets (mmx, sse, etc..) the call is the same for intel and amd.. so long as the operating system knows what id to send to the processor, one should work no different than the other.. assuming that the code doesn't use sse3 or 3dnow.
unless there's another issue that i'm missing here?

i keep getting execution failed on some segment of operation, after i got on my intel system at work it runs fine

Longhorn is going to be released in a 64bit version, there have already been leaked beta's

 

[ethen]

only 64 or both?

 

[EightySix Four]

both, they wouldn't reease an "only" version, considering the mainstream is 90% 32bit

what amd processor are you using? if you're not using the 64.. what math libraries did you install? if you installed p4.. then that's probably the source of your error. axp has no sse2.
if you have an athlon 64.. then i have no clue.. but icc will compile for amd processors. so, i would take it up with intel.

 

[ethen]

i'm on athlonn 64, that is why i switched to intel system

No, current benchmarks show winxp 64 bit to be a good 10%+ faster then xp 32 bit in various apps. The ONLY thing it is slower in is games, and that is ati/nvidia's fault for not updating their 64 bit drivers regularly.
