Mobile Intel Arrandale consumes 35W?

Intel's first 32nm Westmere processors are to be released in the fourth quarter of this year. The CPUs will be using the current Nehalem platform and will be released in the flavors Gulftown (high-end hexacore), Clarkdale (midrange dualcore) and Arrandale (a mobile dualcore). Both dualcore Westmere models will feature a 45nm integrated graphics chip, which is constructed conforming the MCM (Multi-Chip-Module) principle, which combines two chips in a single casing. Fudzilla reports that the mobile Arrandale CPI+GPU combination will bear a 35 Watt TDP.

The combination of an Arrandale CPU, an Intel 5-serie-M and wireless network module with the codename Puma Peak or Kilmer Peak will be named the next Centrino platform, codenamed Calpella. The Calpella platform will be more efficient and smaller in size than the current Centrino Montevina platform. In example: a 45nm produced Core 2 Duo T9400 (2.54 GHz) without integrated GPU consumes the same amount of energy as the new Arrandale chip. A Core 2 Duo T9600 clocked at 2.66 GHz has a 25 Watt TDP; add to that the consumption of the Intel GM45's IGP (about 12 Watt) and once again its a bust against the Arrandale combination.

It's likely that apart from the 35 Watt TDP models, some other versions will appear in the (Ultra) Low Voltage segment featuring lower clock frequencies. These processors are expected to bare TDP's of about 20 Watt.
