Intel’s flagship mobile CPU is Core i7 920XM

Intel’s next-generation Clarksfield mobile CPU parts are launching in the last week of September spearheaded by the Core i7 920XM. These chips are based on the desktop Lynnfield CPUs, with dual channel memory and DMI interface.  The Core i7 920XM (eXtreme Mobile) is quad core-octa thread, with the full 8MB of L3 cache, but runs at only 2.0 GHz. To compensate for the low frequency in single-threaded applications, a turbo boost is available to 3.2 GHz.

Intel’s next-generation Clarksfield mobile CPU parts are launching in the last week of September spearheaded by the Core i7 920XM. These chips are based on the desktop Lynnfield CPUs, with dual channel memory and DMI interface.

The Core i7 920XM (eXtreme Mobile) is quad core-octa thread, with the full 8MB of L3 cache, but runs at only 2.0 GHz. To compensate for the low frequency in single-threaded applications, a turbo boost is available to 3.2 GHz. This temporary increase in speed can be achieved on all four cores as long as the TDP is under 55W, which is an extreme figure for a notebook. In addition to the fiery power consumption, the CPU will be priced at over $999, to make for a rather hot and expensive notebook. The performance of the Core i7 920XM will depend largely on how well the turbo boost works.

The other Core i7 mobile parts expected are 820QM (1.73 GHz, 8MB L3) and 720QM (1.6 GHz, 6MB L3), both with a relatively cooler (but still extreme) 45W TDP.

The current top mobile CPU is Core 2 Quad QX9300 which runs at 2.53 GHz based on the previous generation Penryn architecture.
