Core 2 Family

The Intel Core 2 family was the first multicore desktop design from Intel to cut ties with the Pentium 4 architecture used by the Pentium D, Intel's first dual-core processor. All Core 2 processors include unified memory cache and provide better throughput than Pentium 4 and Pentium D processors with higher clock speeds as well as cooler operation.

Despite the name, the Core 2 family includes single-core, dual-core, and quad-core processors.

Core 2 Extreme Processors

Core 2 Extreme processors are available in three series: the quad-core QX9000 and QX6000 series, and the dual-core X6000 series. The following sections discuss the major features of each series.

Core 2 Extreme Processor QX9000 Series

The Core 2 Extreme Processor QX9000 series was Intel's fastest series of processors until the advent of the Core i7 family. It includes the following major features:

  • Four processor cores
  • 12MB L2 cache
  • Intel VT-x support
  • Supports 64-bit operating systems and applications
  • 1333MHz front side bus
  • Based on "Yorkfield" architecture

To learn more, see Intel's ARK website: Core 2 Extreme Processor QX9000 series for desktop.

Core 2 Extreme Processor QX6000 Series

The Core 2 Extreme Processor QX6000 series features a smaller cache size and a lower range of clock speeds than the QX9000 series. Major features include the following:

  • Four processor cores
  • 8MB L2 cache
  • Intel VT-x support
  • Supports 64-bit operating systems and applications
  • 1333MHz front side bus
  • Based on "Kentsfield" architecture

To learn more, see Intel's ARK website: Core 2 Extreme Processor QX6000 series for desktop.

Core 2 Extreme Processor X6000 Series

This processor "series" of one was the first Extreme processor in the Core 2 family, and as such has much more in common with Core 2 Duo E6000 series than the other processors discussed above. Its major features include the following:

  • Two processor cores
  • 4MB L2 cache
  • Intel VT-x support
  • Supports 64-bit operating systems and applications
  • Based on "Conroe" architecture

To learn more, see Intel's ARK website: Core 2 Extreme Processor X6000 series.

Core 2 Quad Processor

Core 2 Quad processors all have four processor cores, but their features are otherwise widely divergent. Core 2 Quad processors are available in three series: Q9000, Q8000, and Q6000. Their major features are described in the following sections.

Core 2 Quad Processor Q9000 Series

The Core 2 Quad Processor Q9000 series is based on the Core 2 Quad Extreme Processor QX9000 series, but with a smaller cache (in most models) and slower clock speeds. It includes the following major features:

  • Four processor cores
  • 6MB or 12MB L2 cache (varies by model)
  • Intel VT-x support
  • Supports 64-bit operating systems and applications
  • 1333MHz front side bus
  • Based on "Yorkfield" architecture

To learn more, see Intel's ARK website: Core 2 Quad Processor Q9000 series for desktop.

Core 2 Quad Processor Q8000 Series

The Core 2 Quad Processor Q8000 series is a slower, smaller cache-sized version of the Q9000 series. It has the following major features:

  • Four processor cores
  • 4MB L2 cache
  • Intel VT-x support in some models
  • Supports 64-bit operating systems and applications
  • 1333MHz front side bus
  • Based on "Yorkfield" architecture

To learn more, see Intel's ARK website: Core 2 Quad Processor Q8000 series.

Core 2 Quad Processor Q6000 Series

The Core 2 Quad Processor Q6000 series is a slower version of the Core 2 Extreme QX6000 series. Major features include the following:

  • Four processor cores
  • 8MB L2 cache
  • Intel VT-x support
  • Supports 64-bit operating systems and applications
  • 1066MHz front side bus
  • Based on "Kentsfield" architecture

To learn more, see Intel's ARK website: Core 2 Quad Processor Q6000 series.

Core 2 Duo Processor

The Core 2 Duo processors were the first members of the Core 2 family and are available in more than two dozen models. Core 2 Duo processors are available in four series: E8000, E7000, E6000, and E4000. Their major features are described in the following sections.

Core 2 Duo Processor E8000 Series

The Core 2 Duo E8000 processor series is the fastest of the Core 2 Duo series. It has the following major features:

  • Two processor cores
  • 6MB L2 cache
  • Intel VT-x support in most models
  • Supports 64-bit operating systems and applications
  • 1333MHz Front Side Bus
  • Based on "Wolfdale" architecture

To learn more, see Intel's ARK website: Core 2 Duo Processor E8000 Series.

Core 2 Duo Processor E7000 Series

The Core 2 Duo E7000 processor series is a smaller cache size and slower version of the E8000 series. It has the following major features:

  • Two processor cores
  • 3MB L2 cache
  • Intel VT-x support in some models
  • Supports 64-bit operating systems and applications
  • 1066MHz Front Side Bus
  • Based on "Wolfdale" architecture
