It's certainly not for 130nm, as it only kicks in at 4200+ and above.

There is a question as to whether it is up-to-date, as the 104W number was floated about 6 months ago, and since then, we've had the Ace's interview, wherein someone claimed TDP would be roughly 89W again, at 90nm.

Other possibilities include:

- It will run hotter at higher speeds.
- This is to allow for better bins, even if most parts will dissipate less.
- It is a "family" TDP, so what's the upper speed limit that this applies to? (And perhaps the Ace's number (89W) is for 90nm parts up through 4000+ ? )
- Room for dual core TDPs?
- Bogus / out-of-date information

The footnote on the chart for future Athlon 64's does NOT say that 104W is THERMAL power, but is talking about the requirements of the power supply.

Why is anyone upset about an Iccmax of 80A at 1.3 volts?

The datasheet for Intel P4's on 90 nm says that Iccmax is 91A and Vcc is as high as 1.4v. And that is for 3.4 GHz, with no where near the Athlon 64's 4200+ performance.

See page 22 of the Intel spec for 90nm P4's: ftp://download.intel.com/design/Pentium4/datashts/30056102.pdf
