A major difference among these processors is that the desktop Pentium Dual Core processors have a TDP of only 65 W while the Pentium D ranges between 95 and 130 W. Additionally, the fastest-clocked Pentium D has a factory boundary of 3.73 GHz, while the fastest-clocked desktop Pentium Dual-Core reaches 3.2 GHz. In contrast, the Pentium D processors have either 2 or 4 MB of non-shared L2 cache. Below the 2 or 4 MB of shared-L2-cache-enabled Core 2 Duo, the desktop Pentium Dual-Core has 1 or 2 MB of shared L2 Cache. The Desktop E6000 series and the OEM-only mobile Pentium SU2000 and all later models were always called Pentium, but the Desktop Pentium Dual-Core E2000 and E5000 series processors had to be rebranded.Īlthough using the Pentium name, the desktop Pentium Dual-Core is based on the Core microarchitecture, which can clearly be seen when comparing the specification to the Pentium D, which is based on the NetBurst microarchitecture first introduced in the Pentium 4. The Pentium Dual-Core brand has been discontinued in early 2010 and replaced by the Pentium name. List of Intel Pentium Dual-Core microprocessors

Some processors were sold under both names, but the newer E5400 through E6800 desktop and SU4100/T4x00 mobile processors were not officially part of the Pentium Dual-Core line. Throughout 2009, Intel changed the name back from Pentium Dual-Core to Pentium in its publications. A single-core Conroe-L with 1 MB cache was deemed as not strong enough to distinguish the planned Pentiums from the Celerons, so it was replaced by dual-core central processing units (CPU), adding 'Dual-Core' to the line's name.

The identification numbers for those planned Pentiums were similar to the numbers of the latter Pentium Dual-Core microprocessors, but with the first digit '1', instead of '2', suggesting their single-core function.

In 2006, Intel announced a plan to return the Pentium trademark from retirement to the market, as a moniker of low-cost Core microarchitecture processors based on the single-core Conroe-L but with 1 MB of cache.
