Its main processing gain comes from a widening of its internal datapaths and the inclusion of more of just about everything that has been proven to work in earlier Intel designs. The Intel Core 2 Duo (Merom) employs 64-bit operation compared to the 32-bit Core Duo derived-Yonah. Our own test results show the Core 2 Duo outperforms both the Core Duo and the AMD Turion 64 X2, but that doesn’t take into account the reduced clock speed and L2 cache memory, which is discussed further on ! The nearest rival to the Pentium Dual Core processors is the AMD Turion 64 X2. These restrictions noticeably affect the performance of the processor, but then it is very reasonably priced compared to its nearest competitors. The 2nd level cache is still 1MB.Ĭlearly, by using a lower clock frequency and half the available L2 cache, the Pentium Dual Core is targeted at the lower end of the Notebook market leaving the Core brand to the higher end (see below for how the Pentium Dual Core brand also sources the desktop market). The T4xxx Series Pentium Dual Cores is based on the Penryn core with 800 MHz FSB and produced in 45nm. These processors are based on the Merom, which is Intel’s mobile version of the Core 2 Duo, and again, have only 1MB of L2 cache enabled and run at a lower clock speed than their Core 2 Duo counterparts. Subsequent Pentium Dual Core processors based on Core 2 Duo were released in the form of the T2310, T2330, and T2370 (see table below) in Q4 2007.
They closely resemble the Core Duo T2050 processor with the exception of having 1 MB L2 cache instead of 2 MB, and a 533 MHz FSB. The new Pentium Dual Core brand appeared in notebook computers in early 2007 as the processors T2060, T2080, and T2130 based on the 32-bit Yonah core derived from the Pentium M. The Pentium Dual Core was originally based on the Core Duo but more recently we have seen releases based on the Core 2 Duo. As the name suggests, it has two processor cores executing in parallel using the same shared memory. The Pentium Dual Core is the Intel brand covering their low price dual core processor range used in notebook computers.
