New Xeon CPU Hot and Underpowered 293
Kasracer writes "Web Sites The Register and GamePC received several of the new dual-core processors from Intel, dubbed 'Paxville', and ran a battery of tests on them. What did they find? From the article: 'There's no doubt about it, Intel's dual-core Xeons are their most power hungry Xeons to date ... Even when idling, two dual-core Xeons consume nearly 400W of power at any given time, which is amazingly high, even by Intel's standards ... their new dual-core chips (while powerful in their own right) simply are bested across the board by AMD's dual-core Opteron processors. Even worse, the Opterons typically perform much better while running at slower clock speeds and only having half the amount of on-die L2 cache to utilize.'"

Even if Intel eventually hits a process wall, they'll still be able to rest on their huge manufacturing capacity. For the past 5ish years, Intel has been building bigger chips than AMD, mostly in terms of L2 cache. It's not necessarily the best way to improve performance, but it's fairly easy, and leverages Intel's manufacturing strengths. Intel can afford to crank out dies 50-100% larger than an equivalent AMD die, and still make money at it, and still not run out of capacity. The reason Intel has been having shortages of late in the chipset arena is not lack of capacity but bad capacity management. They mis-read the market 3ish months ago and are paying for it now.

The first wave of it was folks starting to harp about the amount of noise that most PCs make. While the Mini-ITX folks were already using fanless systems to reduce noise in specialized application, I think the fanless iMac gave momentum to the movement. At least, that little acryllic cube was cool enough to generate lots of press about being nearly silent.
Then there were the folks that started buying laptops instead of desktops due to the noise / form-factor / lifestyle choices. Laptops are easier to hide away, can be setup anywhere in the house on a whim, and laptops used to be pretty quiet.
Hard drive manufacturers switched over to fluid bearing drives a few years ago. At first, it was a marketing thing that allowed them to differentiate themselves from the pack. Now, I don't think you can find too many drive makers who are still making noisy ball bearing drives.
Energy costs have also gone up in the past few years. My electricty bill has gone from ~$40/mo up to ~$120/mo and I'm starting to consider whether I really want 4 servers, 3 desktops and a laptop running all the time. (And whether I can pack more storage into fewer watts.) Plus the heat issues that all of those systems cause.
PCs are also continuing to move further and further out of the office. As you moving into the living room / kitchen, folks start paying closer attention to noise / power / heat issues. And PCs have gotten powerful enough over the years, that they are "fast enough" for a lot of tasks. They're starting to compete against things like VCRs / DVD players / DVR & PVR (devices which are typically dead-quiet, low-power, and low-heat).
Dell even started selling "quiet" PCs a few years ago (most quiet PCs are also lower energy and lower temperature). Those are nice in an office setting for lowering the ambient noise level (which leads to a less-stressful environment).

Good luck attaching a 1% accurate kelvin sense connection to this. You will also have to design a high performance multiplier circuit to make accurate RMS power measurements in the MHz Range.
But even then, and not considering mechanical difficulties like buried traces/planes, you cannot place this shunt betwwen the cpu and the Power supply (i.e. 1.5V switcher and bulk 1.5V capacitors), because the added inductance and skin effects would probably cause the CPU to malfunction.
So your best bet is to place shunts between the multiple switching coils and 1.5V Caps, which would probably work.
