"AMD has taken advantage of the Intel Developer Forum to reveal a working sample of its mobile dual-core processor.
'We are already the first manufacturer to bring dual core technology to the notebook,' said Bahr Mahony, the division marketing manager of AMD's mobile business segment, referring to the dual-core X2 inside Voodoo's Envy Heavyweight laptop. Although the X2 is a desktop part, its lower power demands make it far more suitable to notebooks than Intel's Pentium D"

"AMD had already announced that it would be rolling out a mobile dual-core processor in 2006. 'We're now narrowing that to the first half of 2006"

Looks like Yonah might have a bit of a battle next year...

To be clear here...the Voodoo X2 laptop is NOT the mobile part they are talking about...
The true dualcore A64s (Turions?) are due in H1 06

Bleh, I'd like to see some power consumption before saying whether or not it's a rival to yonah. I wouldnt expect a 2.2GHz 90nm dual core part to use less than 50 watts of power, even at low voltages so Yonah wont have much competition until AMD's 65nano shrink.

It's tough to know, but as a guide:

1. The X2 has a TDP of 89w
2. Venice 3000 has a TDP of 67w
3. Venice actually runs at 30w under full load

Given those numbers, it's quite possible that the dualcore Turion will run at or below 50w under full load...even at 90nm.

A single core turion has a TDP of 25 wattts. Multiply that by 2 and you get 50 watts...

Exactly...and as we all know, TDP is not an actual usage of watts, it's just a guideline for OEMs on heat. AMD tends to run far cooler and with less power than their TDP number, unlike Intel who tend to run right at their TDP number...

Yes, yes. I meant UNDER 50 watts. Yonah should use around 30ish at full load so AMD needs something similar to be competitive. And, more importantly, it needs some low power core-logic.

Intel cann't compete on the desktop or server yet. But I would say their closer than AMD is on the mobile chip . than when yonah shows up its not even close. But I don't care about the mobile end of it till i can wear it on my wrist. Were's Intels desktop PARTS.

INTEL Dothan RUNS COOLER AT @ 27 WATTS THAN AMD TURION does @ 25WATTS SHOW LINKS THAT SHOW TURION runs cooler than Dothan. LINKS LINKS LINKS

Heat (energy) output is measured in Watts, so it would be impossible for a Dothan to put out less heat at 27 watts than a Turion at 25 Watts. No links are needed, these are basic laws.

Dothan is out turion is out they both been benched . watts used have been benched . So it is possible to show . get links there out there.

I dont even know why I'm replying but here it goes... Though the CPU is attributed a major chunk of the total system consumption you have to remember that the core-logic, the ram and the graphics processors are different on most systems. Intel's graphics and core logic are extremely good on the power consumption side and their dothans have better power management at low to mid loads because they can shut down parts of the CPu in order to save power. So eventhough AMD's Turion max power might be similar or lower than Intel's, their platform and the lower flexibility of their CPUs makes the system's "average" power consumption significantly higher. This will change eventually, of course, we just have to wait for more mature mobile platforms to come out.

AMD came late to the game with Turion, and it shows.

You can bet they won't make the same mistake with their dual-core mobile parts, especially if Intel can get Yonah out the gates on schedule.

I can except that but is Intel going to fall asleep again NO . Intel yonah is going to be good . merom better and penryn is even better yet . can you give me links to what AMD has to counter Intels Coming mobile cpu'S no ok live in your dream world.

Haha, I wonder what YOU know about merom and penryn that makes you think it will be significantly better than Dothan and Yonah. Do you have the chips? Of course not. Have you seen any benchmarks? No. So what do you have? And inquirer article that says there will be significantly less leaking on the 45nano process (and it ONLY TALKS ABOUT CURRENT LEAKAGE, no reference to performance there) and Intel's claims that merom will rule the world performance-wise (They said the same thing about the Itanium, and that didnt go anywhere). A couple of days ago you were sure that merom was going to be an in-order VLIW chip that emulated x86 because some moron posted an article at the inquirer (the same moron who said cell would kill all other cpu architectures) and since it sounded like the thing you wanted to hear so you swallowed it whole (though it made no freaking sense if you know anything about CPUs and software--and physics, for that matter). Speculation is fun and all but dont get so caught up in your self-delusions. Unless you can provide your ideas with significant backing they're nothing more than hot air.

On a separate note :))), one thing that has been worrying me about Intel's new cpus is that they seem to be downplaying single thread performance. They keep claiming that they an just add more cores but coding software to exploit even more cores will be significantly more expensive in applications that are not parallelizable easily.

AMD doesn't whore out promises on vaporware like Intel does.

Intelia...

You have a few mixed and incorrect assumptions there...

1. You are quoting TDPs...this is not what the chips actually do, it's only a guideline spec for OEM manufacturers on what the peak heat values COULD be.
2. Intel and AMD have entirely different goals for determining these guidelines.
3. Intel's TDP is based on how the chips actually perform under typical conditions, both under load and at idle. Intel chips will often reach and sometimes surpass their TDP.
4. AMD's TDP is based on the absolute theoretical maximum the chips can achieve under the worst theoretical conditions. AMD chips will never even hit their TDP.

As to overall battery life, most of this is based on the whole laptop and NOT the CPU (which is certainly not the biggest power drain). Since the Turion is new to the market (compared to the P-M), there are very few Turion notebook designs. As those designs emerge (expect most around January), it's quite evident that they will be at least the P-Ms equal, and they of course will have 64bit in addition...

Ding ding ding! We have a winner!

Bah... I hope to read something about AMD's dual-core mobile before the end of the day. CPU news have been slow today, I was kind of expecting an all-out blitz of information instead of just some cute (well, not really cure, but you should get my meaning) powerpoint slides from Intel.

Wow, I'm actually surprised AMD will try their hand at a Dual-core Turion on the 90nm process... If they can actually pull it off before the die-shrink without having massive heat output then their 65nm dual cores should be very very cool. One question: is socket S1 (684ish pins unless I miss my guess) really going to be dual-channel as Anandtech mentioned (I think)? I'd guess they can pull off the dual-core mobile with a single DDR2 channel 'cause of the massive bandwidth...
