Apparently Intel are planning to release some "Core 2 Solo" ULV (Ultra Low-Voltage) single-core processors for the Sub-Note market sometime in Q3 next year. Though info is still a bit scarce just now, HKEPC make mention of these variants including some brief specs of two Core 2 Solo models to be a part of the upcoming lineup.
Intel just announced its plan on its Core 2 Solo single-core processors in Q3 2007. Instead of normal edition, the upcoming Core 2 Solo has ULV (Ultra Low-Voltage) edition only, targeting for the Sub-Note market. Regarding with the rumor concerning Merom based Celeron M is a dual core, Intel has also announced it should be a single core. The rumor is busted.
In the previous plan, since dual core has been put into a common place, there never exists single core Core 2 Solo but Celeron M 500 for entry-level market. However, since single core has a better power consumption than dual core, Intel decided to make Core 2 Solo ULV for the need Sub-Note market.
The new Core 2 Solo ULV includes two models: U2200 (1.2 GHz/1MB L2/533MHz) and U2100 (1.06 GHz/1MB L2/533MHz). They are set to replace U1500 and U1400. These two models have very good power consumption at 5W only, and are support for Intel VT, EIST, XD Bit and 64.
