New Dothan core

[AWhackWhiteBoy]

The inquier posted of a french website making claims that they overclocked a 2GHz Pentium M Dothan to 2.4GHz, and that its roughly equal to a P4 3.4GHz or an Athlon 64 3400+ at those speeds. God i hope this is true,end the mhz war!

sausage link

Yeah, AMD said that time ago, but Intel and its school of fanboys were like " NO, DEVALUED MHZ FROM A LONGER PIPELINE IS THE WAY".

Integrated memory controller, hyper transport , all these are innovations by AMD, not just speed bumps from a ridiculously long pipeline as what was ment for Intels chips, prescott, tejas, nehalem. Intel have to think, not just slap more Mhz in.

scaling is dead past 130 nm, BTW Intel said they?d have a 10.25Ghz Nehalem chip out in 2005?.Think again

I don't see whats so impressive. An athlon mobile 2600/2800 Overclocked to 2.4Ghz will kill this. Welcome to the party Intel it's only 4 years late. I guess cause it comes from Intel it's cool now right.

Are you positive? Cause my Mobile Barton @ 2.5 still isn't as fast as an A64 3400+ at some things.

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.

And it can't either. Read the article. Translate google french.. First it's a precott which the overclocked bartons destroy. Then the dothan certainly can't keep up with either 64 at same Mhz.

The Dothan is prescott based???? Hmmm... I'll have to do some reading on that...

 

[Zebo]

Here we can only compare what's available.

Scimark Primordia 2.0
Dothan @2.4 = 399
Barton @2.5 = 366


3d mark 2003 CPU
Dothan @2.4 = 783
Barton @2.5 = 769

Once again I'm failed to be impressed when a $100 precessor on four year tech can hang.

 

[Zebo]

No they compared it to prescott.

 

[Jeff7181]

Interesting... now if they can ad x86-64 compatability, it will be the most competition the A64 has seen. One thing I didn't see is how long the pipeline of the Dothan is, and how many instructions per clock cycle. Maybe I skipped over it while looking at the graphs.

 

[Zebo]

They hav'nt told. I bet 11

 

[AWhackWhiteBoy]

everyone is forgetting this is A LAPTOP PROCESSOR, NON-DESKTOP USE. its a LOW POWER mobile processor, its doing great things, and can run at these speeds fine in a laptop with long battery life and still keep up with the best AMD has to offer.

a 2.4ghz barton uses what,approx 100watts?

since when does a barton at 2.4ghz beat an amd 64 3400+?

LOL they have a 35W versions of barton too. A better question is how much juice they have to pump though dothan to get 2.4Ghz See that massive HSF? A lot.

It even beats an FX53 in some benches. I linked it for you.

So, which theory are you trying to prove?... That the 2.4ghz AMD "kills" the Dothan, or that the 2.5ghz AMD can barely "hang"?

 

[SickBeast]

Zebo, you're living in a dream world if you think that AMD is competetive with intel in the mobile arena at this point in time. Two words: BATTERY LIFE.

Well said. Kills it in terms of price. And hangs in terms of performance.

35watts at what frequency,certainly not 2.4, maybe 1.8, 1.9? you think a barton at 266 and 1.8ghz can touch that intel mobile? your forgetting a 2.4ghz barton in most any case is running at 400fsb and is pumping out huge amounts of heat. and who is to say that pasive heatsink is even needed?

edit: even at 2.4ghz a barton DOES NOT equal an amd64 3400+ which is what its compared against. a 2.6 barton would equal a 2.4 dothan, but would also probably pump out 130 or 140 watts.

1.83 is stock Mhz on the 35W moblie barton at excalibur PC.

I have no idea of the resistance of these centrino nor the bartons so interpolation of wattage with increased voltage applied for overclocking is impossible. Anand also failed to do a barton vs. centreno vs. A64 notbook comparison in his reviews so I can't answer this question. 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.

 

[AWhackWhiteBoy]

i agree, when we see the 90nm 64s AMD is going to shift its market in a big way, however for the time being the dothan is still an extremely good chip. if intel does plan to slap two mobile cores on one die, i think AMD will get quite the run for its money.

 

[Zebo]

How much money is it is another question. I know the 1.6 is around $400 but the 2.0 Ghz I can't find prices on. This is a very good chip no doubt. I hesitate to endorse it for two reasons. 1. Cost 2. Power consumption and resistance increases with all chips almost exponentially when overclocked due to leakage and these will be no different.. when they say 25W they mean 1.6 not 2.0 and definitly not 2.4. Sure at 1.6Ghz it's a fine chip power wise and speed wise. If I bought a lappy right now, and my company was paying for it , I'd get one.

 

[Jeff7181]

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."

well that heatsink they tossed on isn't even mounted,its just resting on it with some thermal grease,it can't be too warm. eitherway, theres no offical wattage numbers on the dothan but its suppose to be warmer than the prior pentium m. and yes, price is always a factor reguardless. believe me, most everything in my home is AMD, but i still think AMD sorely lacks in terms of mobile computing. battery life is a big deal for most unless your looking for desktop replacement. either way i can't wait to see how these 90nm 64s fair in the market.

 

[IntelUser2000]

Guys, Look at the specs the French site tested. Dothan/Banias laptop is using PC2100, the highest RAM support can be PC2700.

Dothan's TDP is 21W at 2GHz, which is 3.5W less than Banias at 1.7GHz. The idle power dissipation is 1-1.5W higher though.
