Centrino power, or P4 power? - Page 2

But that article is addressing their attempts at overclocking the CPU. What about default clock settings? Have we any reports on temp?

A good find though arch. Keep em coming. Knowlege is power!

I don't care what the IDF minutes say; Intel says they're scaling the P4 up to 10ghz. That will take YEARS. And the Pentium-M is not nearly as scalable as the P4 architechture is; why do you think they have such a long pipeline? I recall reading somewhere that the Pentium-M tops out at about 2ghz, of course that's what new cores and die shrinks are for.

The P4 isn't going anywhere anytime soon, and you can quote me on that.

The regular P4 can go farther... but I think they want to concentrate on prescott.... anyway, the prescott doesn't run hot. If you did some research you would find on normal clock speeds it only runs afew degrees hotter than the reg. northwood p4.

I am hearing this as well, I was at a MS developes conference last month and the Intel rep echoed that exact statement about 10ghz. I would have asked the AMD rep about the new XP64, but as usuall they were not there.

The Athlon64 has trouble scaling; it can't really go any further (or much further I should say) on 130nm. But AMD is moving to 90nm soon, that should let them clock much higher, especially if they mix some core enhancements into the 90nm changeover. Unfortunately I don't think AMD is going with strained silicon; IIRC they're partnered with IBM for 90nm solutions, and I don't think IBM is using strained silicon in it's CPUs (Apple's G5 is an IBM CPU, the PPC970 IIRC)

On the other hand, AMD has already moved to SoI (Silicon on Insulator), a technology that also improves performance, one that Intel said would be too hard to implement. Well, AMD implemented it Unfortunately since it's ALREADY implemented they can't use it to boost future cores.

I wonder how far die shrinks will go before they hit bottom. I know there are plans to move to 65nm already, but at some point they'll surely hit a limit with traditional processor designs... Who says nanotechnology isn't here, we have 90 nanometer wide parts on CPUs already

Craig, the article does address overclocking, but this is a forshadow of the heat to come with any attempt to scale up the prescott. Second, its not a really a "FIND" Hard OCP is one of the TOP hardware sites on the net with a HUGE HUGE following! I just wish peeps around here would visit sites like Kyle's and Toms more often so they could be better educated!

Gus: "I dont care what IDF says" well you should cuz if Intel says the P4 is dead I dont think AMD is gunna keep building P4's once intel drops them. And Please Quit talking out your arse!! The best estimates for the P4 core never exceeded 4-5ghz, wtf with 10ghz??? and the p4 will never reach those speeds either as INTEL IS DROPPING THE P4!! Why would I quote you on anything?? Id rather quote the Intel Keynote speach showing the P4 being phased out of the roadmap in the next year!

Mario, It does run Hot! as is the proof in the link I provided.

Guys go read some web reviews of Intel's Developer conference held this Janurary in San Francisco= The P4 is dead- so says Intel.

Umm, two people here say they've heard Intel give the 10ghz quote, and you still call us liers?

Let me type exactly the quote from MaximumPC; I've seen it all over the web, but I have the magazine right here: "Like the Pentium 4, Intel designed the Prescott core to scale up to 5Ghz; other iterations of its architechture (in subsequent CPU releases) will likely be capable of reaching 10Ghz".

OK, so the Prescott will reach 5Ghz. And guess what. After the Prescott there's the Tejas! Maximum PC states that it will likely warrant a name change to P5, however, your bull**** about the Pentium-M becoming Intel's only CPU is just that; total BS.

EDIT: Also, I believe the only roadmap shown at IDF was the Itanium 2 roadmap. You're probably confusing that.

Here's an up-to-date Intel roadmap for 2004 clearly showing the P4 coer lasting through the END of 2004: http://anandtech.com/cpu/showdoc.html?i=1948

Note that this is for socket 478 P4 which is being phased out, which is why the roadmap only goes until Q1 2004. I refer you to the Celeron roadmap on that page which shows P4-cored Celerons through Q4 2004, which is actually in the 2005 calandar year.

EDIT: Intel's OWN ROADMAP shows the P4 through december 2004: http://www.intel.com/products/roadmap/

EDIT: Here's a roadmap into 2005, where you clearly see the P4's Netburst architechture in the form of the Tejas core going through 2005 at speeds rumoured to be up to 9.2ghz before the next core after that, Nehalam:

Now would you please stop talking out of your ass and trying to convince us that the Pentium-M is going to be Intel's only CPU in 2004-2005?

First it was P4 reaches 10 ghz, now its Prescott only goes to 5 GHZ, thanks for proving yourself wrong and saving me the time.


Use quotes more often, your more effective that way. Never did I say that the Pentium M will be intels only cpu in 2004-2005. This is exactly why I dog you, you post crap as I never said that! What I did say is that the P4 is dead, so sayeth intel at the 2004 IDF, and that future Intel Flagships will be based on pentium-m architecture because they get the same performance at half the clock and less heat.

The Pentium-M is a mobile processor, and it won't be Intel's flagship mainstream desktop processor. That's what the Prescott and Tejas are going to be for.

Anyhow, this entire argument is made moot by the fact that Alienware can and will swap out your motherboard (I asked them) for a new one, that supports the Prescott, or Tejas, or whatever else.

I would imagine they'll do it right now, however there's nothing stopping you from ordering a new CPU From Alienware and doing it yourself at home. Note that they prefer you be on the phone with tech support while you do it.

aynone knows will AW change procesors and chipset on the 51m till the end of the spring?. maybe go for centrino?

prescot is out of the question, couse of the performance cutback on low speeds. to be competitive P4 prescot should be 4 Ghz. supposedly it benefits A LOT from high speeds.

does AW usually have a stand at the CEBIT in hannover??

I doubt they'll go Centrino, that's what the Sentia is for.

There's nowhere to go but Prescott... though they may wait until a Prescott comes out that is faster than a Northwood P4.

Another option they might consider is a mobile version of the Prescott; it would provide the power of the Prescott with less heat.

But I'm just guessing here.
