Successor



The original successor to the Pentium 4 was Tejas, which was scheduled for an early-mid-2005 release. However, it was cancelled a few months after the release of Prescott due to extremely high power consumption (a 2.8 GHz Tejas consumed 150 W of power, compared to around 80 W for a Northwood of the same speed, and 100 W for a comparably clocked Prescott) and development on the NetBurst architecture as a whole ceased, with the exception of the dual-core Pentium D/Extreme Edition and Cedar Mill.

Since May 2005, Intel has released dual-core processors based on the Pentium 4 under the names Pentium D and Pentium Extreme Edition. They represent Intel's shift towards parallelism and their intent is to eventually make the bulk of their main processor line dual-core. These came under the code names Smithfield and Presler for the 90 nm and 65 nm parts respectively.

In 2006, Intel had plans to work further on the Pentium 4 Cedar Mill architecture to develop a 9 GHz Pentium 4. These plans were eventually scrapped in favour of developing the Intel Core microarchitecture.

The ultimate successors to Pentium 4 are the Intel Core 2 processors using the "Conroe" core based upon the Intel Core microarchitecture, released on July 27, 2006. Intel Core 2 processors have, so far, only been released as dual and quad core processors. Single Core counterparts are present in the Intel Core line, primarily for the OEM market.
