Info on Dothan Successor

[perkam]

Seeing as how, thanks to Kyosen, etc, the Dothan has been getting a lot of attention. However, I happened to find this on Endian.net about the Dothan's successor:


Intel's Yonah: Mobile chip, succeeding Dothan in the power optimized notebook segment including HyperThreading. Will use the Alviso-GM chipset. Believed to be designed around two Dothan cores, each with 2MB of cache. Earlier listed as a 90nm chip in 04-H2.
Yonah (sometimes referred to as Jonah) is part of the Napa Centrino platform, succeeding Sonoma.

Coming out in Q1, 2006 -> YES !! TWO DOTHANs on one chip - :slobber: :slobber: :slobber:

Though it is confirmed to be a 65nm chip.

The Inq has these articles to add:

Intel's Yonah: a dual core thin and light Pentium M (http://www.theinquirer.net/?article=19149)

Intel shows off dual core Pentium Ms (http://www.theinquirer.net/?article=18329)

I guess Intel's answer to the Athlon 2500+ Mobile came "better late than never" in the Dothan :p:

2500+ mobile...AMD also has a LV mobile A64. the 2700, 2800, and I believe theres a 3000 as well.

nice

Two cores with 2MB of cache! Gotta love that.

[Kanavit]

isn't Intel dual core cache better than AMD's dual core cache because it shares the same cache or something? can someone fill me in on this matter? i read this somewhere, and forgot it.

[HawainPanda]

yeah, it was on the inquirer too. i also forgot..lol..dope!

OOPS, forgot to link the MAIN article here (srry):

http://www.theinquirer.net/?article=19493

Intel is confident about its dual core solutions not only because it will be releasing them (probably) before AMD does, but mainly because Intel's dual cores will have a shared cache of 4MB(:eek: :eek: :eek:) while AMD dual core's will rely on their own independent caches - making them hotter and slower - at least according to intel.

mmmm...not shared...then what is the HT link for between the two processors? Just for for show? Comeon! That doesn't seem like the whole truth there.
As for intel getting dual core out before AMD...AMD does seem farther ahead of Intel in the dual "battle field".
AMD- core designed from ground up so dual core will work just fine, built on process AMD is failar with.
Intel-Dual cores based on core not meant for that perpose, Prescott based, will be on a process Intel will just start using (65nm) meaning that yield issues will be for prown for Intel than AMD I believe.
I think AMD will get the dual core out first, but Intel will be later, but (since there later) will have less trouble getting their dual cores out.

I think AMD will get the dual core out first, but Intel will be later, but (since there later) will have less trouble getting their dual cores out.

I guess so, but do consider that AMD right now is WAY too focused on its 4x00/FX-5x line of chips to be worrying about dual cores where as Intel recently ripped up )literally) into pieces its future roadmap JUST so that dual core tech at 65nm could be made cheaper and earlier.

Proof ?? As far as I know, AMD and Intel both use current tech at lower nm which is what allows them to run dual cores. That's for the first dual cores that is. BOTH INTEL AND AMD will have dual cores from the ground up starting Q1 2006 - though AMD's dualcore roadmap isnt as intensive as Intels is.

I am in no way doubting AMD's Dual-Core tech and its ability to deliver it --> a dual core A64 mobile at 2.5 Ghz stock with 4mb cache is nothing you can easily take away from.

Look around, the A64 core was designed so that AMD could add another core onto the die without any kind of extreme trouble. WHy do I think Intel maybe just alittle later than AMD?
AMD core is already designed, it *shouldn't* run hot, its going to be released on the 90nm process which AMD will be more familar with.
Intel core must be worked on, it will be on a new process which means that yields won't be as good, The first dual cores appear to be Prescott based, I say appear because I don't know 100% sure that they are, I have to say their not Dothan based considering 3.2ghz would be quite a leap and LN so far is the only way to get there on current dothans.

[perkam]

The first dual cores appear to be Prescott based

Just because its 90nm doesnt automatically make it Prescott based. Intel has been working on more than one 90nm core for a while. More info here:

http://www.endian.net

Lets not get under the impression that whats out there on 90nm is the only tech Intel has. That, however, will not help intel in the upcoming year as its market share WILL probably sag due to the 4ghz cancellation and redirection of its roadmaps.

yeah I know their are other 90nm cores...I guess I didn't think it could be one of those cores...I forgot :( o'well. Yeah 90nm cores if there designed correctly won't put off alot of heat, I guess I just didn't think Intel would do a rework of their core this late in the game. o'well

[perkam]

I just didn't think Intel would do a rework of their core this late in the game.

What else do you think the reason was for the ripping up of Intel roadmaps like a week ago. IMO, it probably got scared of the spy info on AMD dual cores lol

[jjcom]

yeah probly :D AMD just seems alittle ahead on the game, but this will be hard for them to make the core. Intel maynot have a design set in stone, AMD does. We know AMD can make dual core chips, but how many? What will we see?

The desktop part - Smithfield - is expected to be NetBurst based (two Prescotts on single die). According to Digitimes, Smithfield will have typical thermal power in 95W to 130W range. It is not clear whether Smithfield will work in current 119 Amps motherboards.

The mobile part - Yonah - is expected to be a new design with typical power of 50W and 2MB L2 cache total. It is not likely Yonah will be two Dothans because Dothan does not support 64bit instructions what is unacceptable for year 2006 CPU.

[jjcom]

I'm going to guess that its going to be a Dothan with AMD64 instruction set. Which makes sense....man 130W CPU. That is really bad! Intel really needs to work...that water cooling thing maybe standard on these dual cores...just a guess.
