QX9650 on Anandtech
A very long and interesting article: http://www.anandtech.com/cpuchipsets/sh ... spx?i=3184
It's about overclocking... BUT! Here's something interesting for SPCR
3 GHz, 10W idle, 54W full load on stock voltage, and able to be significantly undervolted? Yes, please!

zoob, they're testing the first of the 45nm chips, it's the first (so far only) 45nm chip, hence the long article with much ado about power measuring etc. Yours chip is (most likely) a 65nm chip hence the need for more voltage and more watts.
Now if my motherboard will only take one... (P965 based - so not very likely)
[edit: just looked it up and it will take a 45nm CPU]

And now some bad news:
http://www.theinquirer.net/gb/inquirer/ ... ads-report
ACCORDING TO A REPORT, Intel has decided to postpone the launch of its 45nm quad-core CPUs because AMD is in such a mess.

Still, if you have the $$, the QX9650 is out now (only desktop chip on 45nm - there are dual socket xeon's on 45nm too, but they won't go in a desktop board). The article above applies to the lower clocked Q9300, Q9450 and Q9550 versions.
I guess it kinda makes sense for them, nobody to compete with in the high-end market, so they can get rid of the old stock before introducing the new models. Not nice for us though.
I've got a QX9650... it's an ES, but I've got an additional retail chip coming along as well.SebRad wrote:zoob, they're testing the first of the 45nm chips, it's the first (so far only) 45nm chip, hence the long article with much ado about power measuring etc. Yours chip is (most likely) a 65nm chip hence the need for more voltage and more watts.

It’s one of the most interesting articles that I’ve read on over-clocking and the power data for the 45nm process seems unprecedented even taking into account that it must be a particularly sweet chip.
One of the things that stands out for me is the difference between the power consumption at idle at 1.2GHz and at load at 3.4GHz; it’s 86W AC.
Extrapolating from this and my own experience with a Q6600 G0 suggests that you could build a 3.4GHz Quad core system that consumes ~140W AC at full load. That’s running Prime95 so real-world applications will consume less. Cooling that will be a breeze, almost literally.
GHz/Idle power/Load power (Prime95)
1.2/208/220W
3.4/225/294W

Xbitlabs has a review of Phenom today and they compare power consumption against 45 & 65nm dual and quad core Intel CPUs. It’s not pretty:

The Core 2 Quad Q9450 is also an engineering sample and this is fairly common practice for pre-release reviews such as this.NyteOwl wrote:That Phenom 9900 must be an engineering sample as afaik AMD have not released Phenoms over 9600 to the retail channel yet due t some manufacturing problems.
There are strong rumours that Intel’s 45nm process has issues so until Intel and AMD release these chips it’s wise to take these figures as indicative which many of you will do anyway.

It maybe they don't want to be seen as a monopoly. Even GM and Ford did not want Chrysler to go belly up in the 1980's.austinbike wrote:45nm = lower production costs for intel.
There is no way they are sticking with 65nm if 45nm is healthy.
Something stinks in denmark.
I heard some rumors that Phenoms, because of their design, won't OC well, ie they don't like FSB changes. The rumor continues that AMD may offer an unlocked version like the Black Edition for us psycho OC-ers.
The latest Brisbane stepping is killer.
