Well, people probably saw the title of this thread, saw an article link and automatically assumed the worst. It's not like you clarified it at all....

Yeah, I know. I'm just trying to give somebody a hard time. I don't see any reason why that power saving technique should be different from current SpeedStep tech. If the laptop only needs 1 core, it should shut the other one off. Then, if it doesn't need much out of that 1 core, it can slow it down to 800mhz give or take. That would put dual cores at basically the same power consumption as current pentium M's when in battery mode doing internet/email/word docs.

Although it will be awhile before dual core becomes useful, I still really like the idea. I might be disappointed if I can't figure out a way to get a dual core in my XPS 2. Disappointed, but definitely not heart-broken or emotionally distraught.

Now, I know that alot of us on here, no more than others. Has anyone heard by chance of a dual core chip being able to work in the XPS2.... that would just make me cry with joy..... I heard about 3 months ago, everyone saying it was not going to be possible... just wondering if some Comps. changed their mind....

That is going to play hell with the process scheduler in the windows or linux kernels. I'm not sure code is included to handle hot removal of a processor (solaris can do this).

Then there is the irony of paying for a dual cpu laptop and only getting half of what you pay for when running on battery. based on what I have read, the 2nd core is OFF on battery otherwise you lose roughly 1/3 of the battery life.

Extreme edition: Good! This is a good choice for those looking for a power machine who don't mind sacrificing battery life to do it. Not everyone will choose it, but being a power user (I can run excel macros where I can walk away from the machine for 15 minutes to go get coffee) there are those who can use it. And if someone wants the same, say XPS Gen 3 (Yonah) machine without the battery sacrifice, just choose a lower speed cpu. It's good for both worlds.

As for dual cores, they'll be useful. Even if one core is way down in speed, it can at least keep up with "system processing" that goes on in the background of all game playing.

No Yonah won't go into a Gen2. This has been repeated at enough places sourcing quiet Intel sources for months. IIRC, there is a new number of pins for Yonah, so even physically you won't be able to do so. Now there will be a Yonah single core version, one at 533mhz bus which "might" provide an upgrade for current Dothan users, and provide the improved SSE23 and ALU improvements of Yonah to single core users. I'm not sure on that one.

Yes, I pointed that out earlier. Dual core doesn't seem to make sense for laptops since you shut one core off running on battery. But hey? How's that different from hot removal? If you unplug your laptop, then it shuts one core off...the programs still instantly lose one CPU and the OS will have to organize the threads again.

I don't know as much as I'd like to about threading, so please explain the difference between these situations.

Remember gents,

Dual core is great for desktop work, but not a big advantage for gaming.

I would say that if you use your rig for everything, get a DC

If you're just going to game like crazy, surf the net, write papers, and the like.

Get a lappy now, no reason to wait...

The people waging on dual core also wage on multithreaded games.

I know they do and so far, I have not heard of any in deveopment, have you?

Its like 64 bit gaming, people are freaking over that too and they really shouldn't. Lets get the OS to run right and tight and then worry about the games.

SLi lappies is what people should be waiting for.

Dual Core CPU's are not going to effect games nearly the way people think because its the GPU doing all of the work anyway.

Like I said, SLi is a different story.

I think you will see SLi in lappies before dual core games... Just my opinion.

Oh.

The only thing I'm worried about is that we're kind of taking steps backwards in terms of trying to achieve better battery life in mobile chips, with the extreme edition. Obviously, it consumes less power than the Prescott desktop chips and such that were and are being dumped into some gaming laptops, but it doesn't consume ENOUGH less to make much of a dent in battery life unless Intel has come up with some amazing power saving scheme for the chip.
well assuming that yonah is 50 watts, that's still a savings of over 30 watts over the p4 architecture. i think that's a pretty big savings. also that doesnt take into account how the yonah extreme will blow the p4 chips out of the water performance wise.
