Dothan Power!

[macci]

Noticed a Very interesting article over at x86 secrect.
They have managed to get a 0.09um PentiumM (Dothan) rig for some testing.

LINK (http://www.x86-secret.com/articles/cpu/dothan/dothan-5.htm)

Totally insane stuff if you consider that its actually a laptop system!!

Check this out too:

Dothan @2.4GHz 120FSB - SuperPi 1M = 34sec (http://www.x86-secret.com/pics/cpu/dothan/trash8b.jpg)

[bias_hjorth]

OC link broken :( but 34sec on a 2.4... thats nice -- shows some hardcore scaling :)

[macci]

One more pic from the article :D

[Djuice]

Totally insane scores... Now how do we get our hands on one....

[jan]

The cpu is not the problem.
what we need are good boards

[Fewture]

I saw that article the other day.. too bad it won't fit in an overclockers mobo. Real nice cpu :)

[macci]

Imagine That CPU on a desktop mobo..at 200+FSB....running at 3GHz...etc etc :D

[dpa]

thats one nice cpu..

[Djuice]

Yeah, and that would be the end of the AMD-FX reign...

[eva2000]

there's a reason i've always loved centrinos from the moment i heard about them :D

[Peen]

and its just running single channel DDR333 , so says the link.

Dual channel 800FSB :slobber:

[MightyOne]

Now why can't SiS or somebody else realize what a great opportunity this would be to grab a fair share of the market and give us a desktop chipset for this thing ... :mad:

As those chips can clock down to 600MHz when in Stand-By, do they do it via FSB or Multi? I'd guess that it's Multi, as all Pentium Ms clock down to 600MHz ... easier to do with 6x100MHz than with different FSBs for different CPUs - and that would make them unlocked CPUs, wouldn't it? ;)

edit:
Those things are available for 300€ (735, 1,7GHz) and 430€ (745, 1,8GHz) respectively here, how are the prices elsewhere?

[DjTonic]

OMG great new Intel's Weapon :p: :eek: :D

:toast:

[saaya]

they are not unlocked and the desktop boards might default them to the lowest multi wich is 6x

there is no way to change the multis of those procs, at least not that i know of. but in theory they should be accessable with a program like crystal cpu

[Kanavit]

Dothan only has 100mhz system bus, imagine if it had 200fsb like northwood. I wish newegg started selling Pentium-M(Dothan) chips 2.0ghz 2mb cache , i would buy one with 478package and try to see if my Asus P4P800 can run it.

[root]

Are there any chance to put this mega cpu in desktop mobo ? What socket it uses ?

[Kanavit]

currently, Dothan is only available for laptops and socket 479. i've heard that certain S478 Pentium-M(Banias) works with 478 pins desktop mobos.

[MightyOne]

It is Socket 479, AFAIK ... no 478 packaging on those.

Won't work in any normal desktop boards so far - and of the dedicated boards only the RadiSys LS855 has a halfway decent feature set. The rest of the available boards is Mini-ITX with no AGP slots.

edit: Too slow ... but I haven't heard anything about Banias chips for Socket 478?

[althes]

That is very nice, cant wait for them to go 775.

[Peen]

Dothan is completely different architecture then the P4..... no way bios would work with it, or the board. its not designed too

[yuri]

Looking good, looks like amd might have trouble fighting that chip off. :toast:

[berkut]

SOcket 478 dothans and banias'es DO NOT electricly fit desktop S478's

But do try, they make even more hardcore keychaines :D

[berkut]

its possible to make a nice "slocket", but you would need some pcb making hardware

edit: Too slow ... but I haven't heard anything about Banias chips for Socket 478? here is a list of Pentium-M(Banias) and (Dothan) socket 478 1mb + 2mb L2 cache 1.30-2.0ghz specs.

http://processorfinder.intel.com/scripts/default.asp?chrid=942

SL7EM 2.00 GHz 400 MHz 90 nm B1 2 MB 478 pin PPGA
SL6N5 1.70 GHz 400 MHz 0.13 micron B1 1 MB 478 pin PPGA FC-PGA2
SL6FA 1.60 GHz 400 MHz 0.13 micron B1 1 MB 478 pin PPGA FC-PGA2
SL6F9 1.50 GHz 400 MHz 0.13 micron B1 1 MB 478 pin PPGA FC-PGA2
SL6F8 1.40 GHz 400 MHz 0.13 micron B1 1 MB 478 pin PPGA FC-PGA2
SL6N4 1.30 GHz 400 MHz 0.13 micron B1 1 MB 478 pin PPGA FC-PGA2

also they have 479 pin too

SL6N9 1.70 GHz 400 MHz 0.13 micron B1 1 MB 479 pin H-PBGA FC-BGA2
SL6F7 1.60 GHz 400 MHz 0.13 micron B1 1 MB 479 pin H-PBGA FC-BGA2
SL6F6 1.50 GHz 400 MHz 0.13 micron B1 1 MB 479 pin H-PBGA FC-BGA2
SL6N8 1.30 GHz 400 MHz 0.13 micron B1 1 MB 479 pin H-PBGA FC-BGA2
SL6NB 1.20 GHz 400 MHz 0.13 micron B1 1 MB 479 pin H-PBGA FC-BGA2


it is yet undetermine if it will work with i845, i850, i865, or i875 chipsets. you may need a non hyperthreading board. the P6 based Banias and Dothan doesnt share Intel netburst architecture , but it still shares the same quad pumped bus.

So does this mean Intel is replacing Tejas and 4-5ghz with Dothan and 1.7-20ghz, are we going to see lga775 Dothan's or is Intel going to keep ticking with Prescotts for their desktops???

a nice 2ghz Dothan in a lga775 board might just make its way into my PC over a 3000+ A64...

a nice 2ghz Dothan in a lga775 board might just make its way into my PC over a 3000+ A64... Tejas has been cancelled and scrapped, however LGA 775 will be Inte's next socket platform. According to Anandtech, Only Prescott, Dothan, Banias, Celeron ULV, and P4 EE will survive to new LGA 775 platform. http://www.anandtech.com/guides/showdoc.html?i=2048

Prescott model number 720 will have new 1066mhz fsb and 2mb L2 cache with 3.73ghz frequency. P4 EE will have 1066mhz fsb 2mb L2 cache, and 2mb L3 cache @ 3.46ghz. i suspect these chips are gonna go against socket 939 A64 3700+ and A64 Fx-55 chips. All Intel processors will use LGA 775 eventually, including Dothan and Banias according to the Roadmap provided by Anandtech.

[scrible88]

These look awesome, imagine on oc'ed to 3ghz+ paired with a 6800u or x800xt.

[Speed_Mechanic]

Earlier, there were no plans for making Dothan a desktop CPU. With Tejas cancelled, changes like this always have the possibility of occurring. But it's still not expected.

Plans hinted at Intel waiting until Merom/Conroe (2006) cores before we saw P-M line becoming a mainstream desktop processor. With the cancellation of Tejas, Intel indicated that they planned to have Yonah (H2 2005, and the follower to Dothan) fit into desktop CPU's.

There's nothing really stopping motherboard makers from taking Intel's i855-PM/ICH4-M chipset and creating an ATX motherboard based on it (with AGP 4X slot).

We may or may not see a motherboard maker taking this idea and creating an ATX motherboard with the i915-PM ('Alviso') / ICH6-M mobile chipset (with PCI Express x16 slot) for 'Dothan' 533FSB processors. This chipset is said to be introduced sometime around Q4 2004, a while after Intel brings out their 'Grantsdale' and 'Alderwood' desktop chipsets.

For now, Dothan is for laptops only.... Prescott is Intel's only desktop CPU available...

In late 2005 we will see dual core Merom's (the next gen Dothan) with higher clockspeed, FSB, and 2 CPU's on one core for desktop systems. That CPU will rock, but until then, AMD has a chance to make huge gains in marketshare.

[LikwidKool]

Funny how it seems we are going backwards now in the mghz race!

I am liking this though.

[Kanavit]

I foresee Dothan as being my next desktop chip. i may wait for the Pentium-M 2.13ghz 2m L2 533fsb version, hopefully it will work with my P4P800 mobo with bios 1017 for new cpu. probably 40 sec Super PI 1mb stock. lol

[cpulloverclock]

"Doté d'une fréquence de bus qui passera de 100 MHz (400 QDR) Ã:banana: 133 MHz (533 QDR), ce nouveau Dothan sera épaulé par un chipset dérivé du Grantsdale qui supporte la DDR400 sur deux canaux. "

apparently a new dothan 533FSB will be available in a few months, not a DUAL CHANNEL system in forecast

The 'Alviso' (i915-PM) chipset will support Dual-Channel DDR/DDR2.

[Orak]

deam... good performance .. thats a good one i think :)

[Speed_Mechanic]

For those who do not wish to wait for 'Alviso' chipset, a mATX motherboard based on Intel's current mobile chipset (i855 + ICH4-M) is available this week according to pc-watch.

http://www.pfu.fujitsu.com/prodes/product/boardcomputer/pdf/catalog/pd-41pm160m1.pdf

Specs are limited, as it's based on an aging chipset, but it's still a capable board simply because it has an AGP4X slot. Stick a high-end graphics card and a high-end cooling system and see how it benches, no?

Wouldn't expect high 3DMark scores, but with a CPU clock above 2.4GHz, it may run a nice SuperPI.

[nailbomb]

Those numbers are just sick :) The next couple years are going to be VERY interesting indeed.

i am so jealous of your av... i wish i found it before you.

I really dig that 70's lookin hair :p
