  It's not supposed to compete against the 3800+ (But it would have been nice if it could match X2s clock-for-clock, at least, since X2s will hit 2.6GHz soon enough) and it does very considering its power consumption.
  
  I must say that it looks like 90nm dual-core Turions will be a very good match for these though (which I still dont think they'll hit 35W max power draw), since Yonah on a mobile chipset only uses 25% less power than a "high-voltage" X2 on a desktop chipset.

  18% less power at idle and 33% less power under load supposedly with the same video card, HDD, and all of that (they didn't actually reiterate the test system configurations, just said they were the same and were the same as configured in a different article).
  
  Remember... the board tested with Yonah was a desktop version board, not a laptop configuration AND both the Yonah and the board it was on were pre-production test boards. It used the 945G chipset but that doesn't mean that the board was designed in any way like a laptop board. Of course, all of the numbers (performance and power) are subject to change (can be up or down) when Yonah and boards are in production.
  
  I wish the Yonah would have been faster, too. It does well in some areas (nearly equaling the X2 4200 which is 200MHz faster clocked) but others it seems to fall down. It looks like the FPUs weren't beefed up enough and it still isn't up to par main memory wise as the Athlon64s.

  Please post some overclocked scores!

  Please lower the multiplier, run 200fsb with the ddr2 in 1:1 mode and give us a true apples to apples comparison against X2.
  
  EIST should work with clockgen in windows if the bios is poor on your board.
  
  Thanks

  As other PC industry folks have already stated, Yonah, aka YAWNER, is too little, too late and not worth even bothering with. When Conroe and friends arrive, AMD will have already released faster, cheaper X2 CPUs so Intel is still 2 years behind and loosing ground. Why would anyone buy an obsolete, under-performing CPU that requires a new Mobo? Makes no sense.

  No, they are fine. They are as fast as the X2 3800+ processors in almost everything (except heavy non-SSE floating point), and they consume less. Everything depends on the price Intel will ask for them.
  And I would certainly prefer that Yonah over a Pentium D 830. Why there was no power comparison to the D 830 line too?

  Yonah looks ok for notebooks. I mean its slower than AMD X2 but as a mobile processor, its real competitors are AMD Turion and Sempron and Pentium Centrino not X2.
  
  I do hope Intel wont price gorge dual core notebook processors, hopefully they only be slightly more expensive than Dothan.

  Actually, it's real competitor is the dual core Turion...I suspect we shall see AMD extend their lead into the mobile sector this next year.
  
  I must say that I had one dissapointment with this preview...
  While Anand finished with power numbers, he didn't tell us how or what they measured. For example, was it the whole system or just the CPU? Did it include the Northbridge numbers for Yonah (since these are alreeady included in the X2)? How does this compare to the numbers from the Turion?

  Well you suspect wrong, which I suspect, in your case, is quite often. First, there are no dual core Turions on the horizon. Second, AMD is not having much success in that sector because intel's platform strategy is useful for laptop builders. Third, Turion power consumption isnt quite on the same level as Dothan. They will need to move to 65nm before building Turion laptops.

  Sigh...have you ever heard of Google before? It's a wonderful little search engine that would have shown you inumerable articles on the Dual Core Turion being released in early 2006...

  Gee...then increasing their marketshare by 75% from Q2 to Q3 was unsuccessful, eh?

  If someone could translate this for me, I'd be happy to respond...
