holy crap :slobber: thats awesome.
I knew that they are a lot better clock/clock then the A64 FX.

love the 2MB cache :banana:

Nice doing!

[ant1]

2.5 @ 1.3v :o Now push it hard! :D

[craig588]

Intel CPUs are typically much better at superpi, have you done any 3d tests?

impressive time for the clock :slobber:

[enzoR]

omg it seems like 3ghz is easy for that chip. he just needs a proper mobo. that would blow everything out of the water! :slobber:

[crotale]

Those chips, unlocked, coupled with dual channel and some BH-5 at 250 FSB 1:1.
lovely.

[Shade00]

Yep... now if only we could get that mobo here. :( That's what I'll be waiting for.

[jjcom]

Wonder when we will get those boards...that would be nice! But I could see Intel doing something to the P-M to limit overclocking...like on the 9xx chipsets. :(

[Shade00]

But that board's already out... we just need to see it in the retail market here. If it shows up by Christmas, I might have to go for one.

[The Stilt]

Luckily I got one of these chips (http://www.akiba-pc.com/2026WLMi/755.jpg), but where hell can I find one of those mobos :(

http://www.akiba-pc.com/2026WLMi/2.4GHz.jpg

[jjcom]

IT is???? Cool where can i find one of them things! That would be very nice to try out...but I'm more intersted in other things right now.

[masterofpuppets]

Nice! Ya gotta love those crazy japanese with their funny fonts and their windows 2003.

[Ailleur]

29s air cooled cpu... Seems everyone knows what Intel's future should be, exept Intel!

[jjcom]

Dothan should be Intel's next chip. When are we going to see those chips?? I know at one point wasn't Intel going to release desktop versions. Now 6months later or maybe more...we still don't see it.

[Parradux]

Anyone got a Clockgen for a laptop?

I got a 2.0 Dothan that I can experiment a little with.

Exact model:
ASUS M6Bne

[Kunaak]

incredible results.

now if only intel would get thier head outta thier butt, we might have some good hardware to play with from them :)

you can get this motherboard here.

http://aopen.jp/products/store/

assuming you can read japanese and they ship to you.
might be better if you knew someone in japan though...

[jjcom]

This is really making me think...
If Intel could make chips like that....why are we not seeing them until now? I mean the Pentium M has been out for a little while. 1.3v and they can do 2.5ghz...I wonder if this means that yeilds are not good.

[Kunaak]

according to this, its a japan only item.

http://global.aopen.com.tw/products/mb/i855GMEm-LFS.htm

look at the part number

[Romaster]

as intel is with most things, they are always cautious when it comes to high clocks and take it one step at a time... I'm sure dothan is intels next big desktop idea since presscott SUX!.. but by the time intel makes a retail 3ghz dothan.. it will probably be 2 revisions later and a longer pipeline resulting in weaker performance.. but still owning any presshot.. guess we'll c :(

nice superpi score you got there.. that easily owns my 3.2E which gets like 39s if i recall correctly...now you just need some watercooling :cool:


have you done any 3d tests?

you seem to miss he is on a geforce2 as he wrote..

Around what does a 939 512cache cpu put out at 2.5ghz 240x10.5 with dcddr 1:1 5-2-2-2 in superpi for compairison?

wow to get 30S SP 1M for me on a A64 3500+ it was 260x11 (2.86 Ghz 1:1 2.5-3-3-7)

That some incredible times for a low clocker. Intel is really going to wreck AMD a new one if/when they release desktop dothans.

[Lithan]

It would seem so, in superpi at least. But remember that even Prescotts beat FX's in superpi. And Prescotts sure aren't faster then FX's in much of anything else.

[HKPolice]

I think Intel has a Crouching Tiger, Hidden Dragon chip on their hands ;)

[Lithan]

My guess is that amd could impliment sse3 and bump fx to 2mb cache if needed and outperform the Dothan.

Ya, but they can't do 2.4Ghz @ 1.3v no matter what... Not even the 90nm ones, at least not yet.

[PnoT]

I could get my friend to order me a few of those mb's from japan if anyone is interested. I'll have a talk with him if i get some of you that PM me for some.

Don't think it'll be worth it since it's only single channel ram, so 3D performance will be crap.

Almost forgot that the Dothan doesn't have intergrated mem controller, so even with dual channel ram, games will still lag behind A64 clock for clock..

My best time at 2.5GHz (and at 276.5 x 9, 1:1, 2-2-2-5-7-16) with FX-53 is 32sec - so that little Dothan is killing even the fastest FX chips clock to clock!! :D
Now whos going to fly to Japan and get us some of these mobos!?? :D

Ya, I'm sure the crazy rich LN2 SuperPI mofos out there would love it :rolleyes:

[Shade00]

I'm going to check with my buddy and see if he might be able to get me one. I think it would be awesome to run a Dothan on the desktop.

[Lithan]

Ya, but they can't do 2.4Ghz @ 1.3v no matter what... Not even the 90nm ones, at least not yet.

Well, I think they could if the power scheme was adjusted (more amps, lower volts). But I agree that they can't at the total wattage of Dothan's... which will make dothans very attractive to me as I've been seriously looking at a silent + low power rig lately. But if and when we can seriously look at Dothans as a desktop alternative is questionable. And I think from a pure performance perspective, A64 will still have the lead.

I think you're a little confused here. You can't just "turn down" the volts and pump up the amps on a CPU. Voltage is determined by the design and speed of a CPU. For example, you can't run an A64 @ 2Ghz with 1v, even if you pump a million amps through it. Amps is determined by the activity/speed and % leakage of the CPU, so it varies. The CPU will use up as much amps as it needs, you can't "force" extra amps through it.

[Lithan]

During cpu design it's determined how much amperage it will draw, just like with any other electrical device. I'd assume this can be controlled to a point, otherwise they are just shooting in the dark to figure out the cpu's power specs.

Edit: Case in point: The low-wattage Opterons with not only lower Voltages than their 'standard' alternatives, but lower maximum amperages as well. And the DUT3C/DLT3C's from not so long ago. DUT3C drew @ max ~31amp at 1.6v, DLT3C drew @ max ~33amp at 1.5v; otherwise the two chips were identical.

[seb87]

wow ..........impressive............

i ve do an articles

[Jupiler]

Looks like the board will be available in Europe by mid-November.
2 stores in Germany already have it listed :

http://www.geizhals.at/deutschland/?such=i855gme&a=17101123

Price : around 240€

[ant1]

Is that an ES or are the multis of Dothans free?

[Shade00]

Lower multis should be available so that the chip can run in lower P-states when on the battery.

[jjcom]

Dothans will be a great processor once Intel gets them out to us. Unlocked Multi...yeah 1200mhz FSB. :D Probly not but nice to dream. Those should turn out to be great processors. 2.5ghz @ 1.3v...think if that thing was cooled with LN....

[WildKard]

It isnt even in a "desktop" environment either, single channel DDR333 memory

Give it some dual channel OCZ 2-2-3 DDR2 @ 1066fsb and hyperthreading and youll really see it fly

[cpulloverclock]

Lower multis should be available so that the chip can run in lower P-states when on the battery.
with a Dothan 2.1G we have a choice from 8 to 21x

The AOpen i855GMEm-LFS wont be the only MB to an extreme oc (vcore availibility for example)

[Mathias-K]

you seem to know something i do not, CPUOC?

When will the 2.1 dorthan come out, and who else are gonna make P-M desktop mobos for OC? :)

[STEvil]

nice ;)

[jjcom]

before you ask I don't remember where I found this:
I don't think Hyperthreading can be used on the Dothan. I BELIEVE that the pipeline is too short for it to be worth while.
And there isn't DDR2 RAM with 2-2-3 timeings. I'm not sure if there will ever be...but by that time..lets hope the DDR 2 has advanced enough for that :D

[cpulloverclock]

yes but I can nothing say

[STEvil]

Yes, there is DDR2 with 2-2-3 (assuming 3 means cas latency here.. everyone writes it differently :rolleyes:).

[saaya]

1.33v!!!!

damn i need to work on my adapter again :D

[jjcom]

sorry I thought you were refering to the future....I'm normally pretty good at seeing which way its written. :( o'well

Can only these desktop Dothans be obtained if your on Intel's special list :p:

That's a good price for Germany. The AOpen i855GMEm-LFS ohashi using is now around 200 Euro in Tokyo.

duan channel in March 2005

[Miles_Teg]

From what I've seen so far, the Dothan vs. Prescott performance difference is around 3:2 average (differs quite a bit per benchmark). So the Pentium M 755 (2GHz) will perform at around P4 530 (3GHz) levels. As the M755 is more then twice as expensive as the Prescott, the Dothan does NOT seem very much like an option to me. Anyway, AMD's 64 (FX) series will still own, even if the Dothan is released for desktops (at comparable prices).

[perkam]

Intel is really going to wreck AMD a new one if/when they release desktop dothans.

I guess Intel knew what it was doing with its 2mb L2 cache roadmap changes earlier this month :D :D :D

I am seriously beginning to consider a 7xx system for my next rig over an LGA 775 system, this stuff is NICE !!!

EDIT: (only read first page and posted :mad: )

Though my only concern with Intel coming back into the fight is that AMD's marketshare is STILL FRAGILE and a 3 Ghz 2 MB chip might end up killing the FXs in value/performance. Of course, AMD is armed with WInchesters and is so to the teeth while the 7xx series is barely available.

still getting better everytime...
