Comments on: HP Pre 3 Hardware Analysis
The Pre 3 arrives with a 1.4Ghz "Snapdragon" 8x55 CPU, easily making it not only the fastest WebOS smartphone yet but also the highest-clocked single-core smartphone currently available or officially announced by any manufacturer. This definitely seem to be the most future-proof, cutting-edge aspect of this device, just like the TouchPad's 1.2 GHz dual-core CPU.
While no official reason for the lack of a dual-core processor in the Pre 2 was given, I would hazard a guess that WebOS 2.x, like Android 2.2, currently lacks the necessary optimizations for dual-core architecture. By necessity, HP's new WebOS smartphones are more legacy-oriented offerings than the new TouchPad, running WebOS 2.2 instead of 3.0. Therefore, a faster single-core CPU makes more sense in the short term, leaving the core-core parts to the heavier lifting done by the TouchPad and version 3.0 of WebOS. However, one thing that is certain is that the new HP-backed WebOS devices are going full speed ahead with Qualcomm Snapdragons and leaving the TI OMAP 3600-series processors behind.
