New Dothan core

[IntelUser2000]

Zebo, that's a laptop, so they need good heatsinks since there isn't much space to dissipate heat.

That 2.5 times increase in idle power dissipation in Dothan is probably 2.5 times the leakage or something.

"When the 30W (1.35V) moblie 64's come along then we should see this centrino excitment wain".

Really? How? Considering in the French site Mobile A64 is practically equal to Dothan at same speed and Dothan is only using PC2100, while it can be used to PC2700. And that 30W is at 1.6GHz, not 2.0GHz(just because they are not releasing one).

Dothan may not be warmer than Banias since the die size is 1-2 mm2 bigger at lower TDP, I know TDP don't tell so much about the actual heat, but its average heat dissipation, so Dothan may even be cooler than Banias. Prescott runs hotter because smaller die size: 112mm2, and higher TDP, 103W vs Northwood die size: 131mm2, lower TDP, 81W. Which makes it like 50% higher temperature.

You're thinking of the stock review at the begining of the review?

But when they overlcoked they opened it up and slapped a slk on it for goodness sakes. Nothing wrong with that perse since it's needed to OC but it also shows just how much cooling is needed (like a barton/64/P4 or any other chip) to run at that kind of performance. It's also implies much more power to get there than we are thinking.


I can't wait till these chips hit desktop so we can do some real comparisons. Until then it looks very Bartonesque with maybe a slight edge on non FPU performance and slightly lower Power. Yes a better chip but better than four year old tech is'nt that impressive to me. I'm done replying to this thread because I'm prone to make assumptions on products that ar'nt even out and done by some no name reviewer.

well at least i got some debate going,this forum needs some

just so long as it doesn't turn into mindless fan boy bantering

 

[Zebo]

I'm only a fanboi to price/performance overclocking. 2.8C wins and 2500/2600 Mobile Xp's win.

Everything else is overpriced unless you including the Duron which is below my performance threashold no matter the price. As for notebooks, these chips win unless you want a desktop replacement then A64 wins. But there is no "deal" in the notebook arena IMO.

They slapped the SLK on the heat pipe, not on the core itself.

And the measured core temps were quite cool, no higher than 30C when running cpu burn for over 2 hours.

I think the more important point is that INtel is now successful copying AMD like whores. I realize some of you (who are quite strange) are fans of intel, amd, nvidia, ati (why no logitech groupies?) but inte's actions the last few months have been pretty funny. Thing is, AMD does not have the resources to make a pure mobile chip. AMD mobile chips are like Intel p4m's and such, Intel designed a different architecture for laptops. But it really is funny that Intel is going the amd64 route, going for a performance rating, dumping the high clock rates with tejas. AMD has remarkable influence for such a small company.

If scaling is truly dead as IBM claims, then we are really in trouble becuase MHz has been the primary source of increasing processor performance. And performance from MHz increases are roughly linear whereas performance increases from bigger more sophisticated designs is much less than linear.

They're going dual core and that's a good thing IMO.

I don't see what so remarkable about it??? Any large bohemoth like Intel is slow to innovate and change. The stuctural nature of such companies simply prevent it. Micorsoft is the same where they now buy tech and apps fom small developers and generally fail at thier internal endevors (MSN/XBOX) surving on thier bread and butter.

Lesson to be learned here: it's does'nt matter what size the org you are competing against you have a shot in the American Dream if you out hussle, out innovate, out manuvuer the massivly funded bohemoths. Even Intel and Mirosoft did it at one time.

why no logitech groupies?)

Actually I'm a mirosoft Bluetooth groupie Love my Blue keyboard and mouse. And microsoft has anyways made the best Keyboards and Mices IMHO.

I read somewhere the fsb on that chip is like 480.....Can intel increase the fsb and lower the multipliers??? I would see intel as doing that in the desktop market now that the memory has adapted to take advanatge of intel and the quad pumped p4.....


http://www.x86-secret.com/articles/cpu/dothan/dothan-7.htm

I think the whole thing was rather impressive when you think of it....

Does it have HT then if it is a prescott based cpu??? If so why is it so hard for you AMD ppl to state this can definitely help the laptop arena where multitasking is often very commonplace....I know its hard!!!

 

[PetNorth]

lol Dothan isn't a Prescott based

Dothan (and Banias) is an evolution of P6 architecture (PIII). Don't have HT. In fact, in these short pipeline CPUs, HT is useless.

I don't see why it matters that this is a mobile processor. It can easily be made into their flagship desktop processor. Also the wattages given don't really mean crap unless they're in terms of 100% CPU usage. All that tells you is how low it's able to throttle down... which I don't really care about, I want to know what it does "balls to the wall."

Where does the saying "balls to the walls" come from?

Like whores? Who exactly do you think designed the x86 architecture in the first place? Certainly wasn't AMD.

I think you fail to realize that a good idea is a good idea no matter who comes up with it or uses it.

Zebo said: All I have to go with is the benchies which imply a centrino is about even with a barton at same Mhz. When the 30W (1.35V) moblie 64's come along then we should see this centrino excitment wain.

What you said above and the benchmark of the overclocked AthlonXP at 2.5GHz says that Athlon64 isn't so good, since the AXP at 2.5GHz beats or equals the A64FX 2.4GHz. So Athlon 64 will not be better off then.

 

[IntelUser2000]

I think in opposition to your saying that Centrino excitement wain, it will be better off, since according to the overclocked AXP's benchmark, A64 isn't much better per clock than AXP.

Exactly. These reviewers create too much hype and act like so-and-so hardware is the second coming, they did it with the 64 too which is a waste of money right now IMO and certainly the FX's are. As far as the mobile 64 30W verions when it really comes out and he price is realsed then we'll chat. Just like with this chip for the desktop.

AXP Only beats FX on a couple benchies. The FX is far and away a better overall chip than the AXP it's price is the problem. Everything in my view is price/performance. If your looking for the best yes get an FX or a EE and call it a day.

exactly what kind of motherboards will these Dothan CPU's fit on though. Looking at the pin structure, it is slightly different then ur 478...
