Delayed debut for Dothan processors now set for February

Sources at Taiwan?s notebook makers have confirmed that Intel will debut three models of its next-generation Pentium M processor, codenamed Dothan, on February 4.

To accelerate the transition to the new processors, Intel has decided to launch a 1.6GHz model. Originally, Intel had planned to start the Dothan processors, manufactured on a 90nm process, at 1.8GHz and later add a 1.7GHz model.

It will be even later than that before you see any shipping units...
Actually probably not. The Banias launch went off pretty well - people started getting their Dell and IBM units about a week after official launch.

February 4 isn't great, but it's not terrible either. I expected Banias to launch in January '03 and it didn't until mid-March '03.

So will a Dothan cpu run much cooler than the Pentium-M/Banias? Thinking about fan noise here.
And will the Dothan laptops have an even greater battery life?

Normally, reducing the size of the fabrication process results in CPUs that can run significantly cooler at the old clock speed or that produce the same heat at a significantly higher clockspeed. Since power consumption produces heat, it is normally reduced concurrently. However, various industry press reports have indicated that Intel's transition from a 130nm to a 90nm fab process has NOT yielded the usual heat and power improvements. I suspect that this is one reason why Intel is delaying the Dothan launch and is coming out with a 1.6GHz version. Given the above, my guess is that you will see little improvement in heat or battery life with the Dothan CPU as compared to the Pentium M.

Since Dothan has twice the L2 Cahce wouldn't the larger L2 Cache draw more power.

Processing will be faster and once the calculations are done, the cache will be turned off. Dothan will use slightly less power if that's the case.

Yes but Dothan is under the Centrino name so any unused cashe should be powered down when not in use.

Anyway what I want to know is if the 802.11g card that is supposed to be available upon Dothan's release will work in current 855 Centrino. And I mean really work with the variable clock and all that jazz. I suspect it will but it may not.

It would be sweet if the card would work, there may be a good chance that it will, but if so where would one buy the card?
What would be crazy is if the new cpus were pin compatible with the centrino motherboards out now... ok heheh thats just wishful thinking.

Check out Dell S&P they sell the Intel 2100 wireless card, don't see why Dell won't sell the 802.11g version in the future.

That would be awesome Dothan + 802.11g :)

Intel Pentium M "Dothan" Launch Date Revealed

Given its higher core frequency and 2MB of cache instead of only 1MB featured by its predecessor, the CPU will consume more energy compared to the Banias despite of thinner 90nm fabrication technology. Earlier this year it was said that TDP of higher-end Dothan processors will be 29W to 31W, while thermal design power of current Pentium M ?Banias? chips is just about 24.5W.
