Intel Shifts Pentium 4 to 64-Bits
Hook, line and sinker. Surprised this was not already posted. This reassures me that Apple is going to continue to use 64 bit. I was concerned up till this point.

Intel shifted the majority of its Pentium 4 processors to 64-bit capability over the weekend.
Intel quietly introduced the Intel 5x1 series, which shifts the existing 775-pin, 32-bit Pentium 4 line?known as the 5xx series?to 64-bit memory addressing.
For customers, all this means is that Intel is encouraging its customers to buy 64-bit chips instead of the older 32-bit Pentium 4s; save for the 64-bit capability, the new 5x1 series is identical to the older 32-bit Pentium 4s, and priced identically. The unspoken message is that a customer will receive 64-bit capability for free.
All of Intel's 775-pin chips now include 5x1 representatives with one exception, ranging from the 3.8-GHz Intel 571 on the high end to the 3-GHz Intel 571. On Intel's price list, the 64-bit version of the Intel 520 is also labeled as the Intel 520.
Prices of the new chips range from $163 to $637, in lots of 1,000 units.

haha Thanks! I wonder if Apple stressed them on this or if it was just a logical progression. Maybe a little bit of both? This will only mean great things when these new machines come out. Sounds like it will be pretty much across the board so we will likely get 64-Bit on both the consumer and pro products.
But yeah, I'd say this clears everything up as much as it can be.
I wonder what the dev machines are? When are they supposed to be delivered? I couldn't imagine that someone hadn't picked up that the machines at WWDC were 64-bit versions, or Apple could just be waiting to ship the machines until Intel made the 64-bit official so they could put them in their boxes.
Just speculating, that's what this place is for.

Apple isn't going to use the Pentium4. You still shouldn't worry about 64 bit support though.

actually, if you count the dev machine as an apple product, they ARE using P4's...how do we know they won't continue to use them? The eMac would be a prime candidate for such a processor.
Because he's listened to Steve at the WWDC keynote. Steve said he hopes to have a shipping Mactel system by WWDC 2006. Thus it is more likely that we'll see a Yonah based system first in the Mac mini, eMac or iMac. Reason? Yonah will have a TBD of 31 watts or less versus today Pentium 4 which has a TBD of 90+ watts for a single core processor.
Considering that an eMac has a CRT and cramped case the Pentium 4 is "not" the prime candidate for such use.
Intel has been shipping 64-bit CPUs for about a year now. I've been running 64-bit CPUs since October of last year.
Intel's move to 64-bit x86 CPUs was driven by competition with AMD. AMD brought out a 64-bit version of their x86 machines about 18 monts ago. People liked that product and it began to hurt Intel's sales. So Intel began shipping 64-bit chips.
This has nothing to do with Apple.

I have a few remarks about this Yonah. First a bit of history, whe IBM switched from 130nm to 90nm there were huge problems and I think for Intel to, but I don't know for sure. ATI and nVidia had problems switching to a smaller die.
Why wouldn't there be problems with the switch to 65nm? They say Q1 for first shipments, but I don't think there will be large quantities.
What do you think?
No offense but this topic is not about Yonah, there are plenty other topics about that. Lets keep to subject please?
like is there more shit to worry about now, like, 32-bit ppc, 32-bit intel, 64-bit ppc, 64-bit intel??
obviously maintaining 4 code branches is not the case, what is the approach here dudes/dudettes ? just curious, as i'm sure quite a number of us are.
how do you write and compile for a 32/64/intel/ppc universal binary?
are there APIs (frameworks??) that abstract out the memory addressing and endian stuff, like the abstracting out of altivec-type functions?

with the move to 64 bits starting now, all of intels cpus will be 64 bit when the macintels come around, will they not?

well, i don't know if yonah will be 64bits

what i've heard is all new intel chips are 64 bit, it's just not 'activated' on some but will be from now on.
I think we're looking at Merom before we get 64bit performance. Intel stated 64bit would consume more battery life.
