brand core

These were both premium parts (branded Core 2 Duo rather than Celeron or Pentium).

Introduced in April 1998, the first Celeron branded CPU was based on the Pentium II branded core.

They phased out the Pentium names from mobile processors first, when the new Yonah chips, branded Core Solo and Core Duo, were released.

Core 2 also introduced a quad-core performance variant to the single- and dual-core chips, branded Core 2 Quad, as well as an enthusiast variant, Core 2 Extreme.

The top-of-the-line Kentsfields were Core 2 Extreme models numbered QX6xx0, while the mainstream ones branded Core 2 Quad were numbered Q6xx0.

Kentsfield is the code name of the first Intel desktop quad core CPU branded Core 2 (and Xeon for lower-end servers and workstations), released on November 2, 2006.

A number of Intel processors since the introduction of the Nehalem microarchitecture (that is, a number of CPU branded Core i5, Core i7, or later) support VT-d, an IOMMU implementation.
