Default AMD Phenom 9950 to dissipate 140W

We’ve learned that soon-to-launch Phenom 9950 will dissipate 140W. The motherboard manufacturers are currently testing their boards to see if they can take it, but most of the boards that can cope with 125W will be able to take care of 140W.

Once you overclock your 125W TDB Phenom 9850 your TDP jumps up anyway, and the board that will let Phenom 9850 overclock will also take good care of Phenom 9950.

Time for a die shrink?

Looks like it.
Now I know why those low cost boards die.

They can't feed sufficient current? Example?

Did you miss: http://www.anandtech.com/mb/showdoc.aspx?i=3279 ? 125W AMD processors were to much for 780G ~$70-100 4/5 phase motherboards. 140W 9950 would be even more of an issue.

Auwch! I did miss that, thx.

9850 aka the board killer Low-end is low-end, no matter what, but if it can't take retail processors then their is something wrong in their philosophy of board design. I do wonder, since the pictured boards don't come with heatsinked MOSFET's, has Anand tested these boards inside a housing where case airflow probable improves MOSFET temperature.

most likely they tested outside case, which is not real world and might indeed be the cause; a recent motherboard tested outside a case failed when under load due to overheating, but placed inside a case with minimal airflow it was rockstable

Not sure I would call $100 low end, but you may be right. Was close to high-end back in Abit IS7 / IC7 days

Anandtech did add a fan, this was the follow up: http://www.anandtech.com/weblog/showpost.aspx?i=427 Still not enough without MOSFET/PWM area heatsinks on some boards...
