2300. Chip lithography. 45 nm. 14 nm. Power consumption (TDP) 65 Watt. 15 Watt. The Core i5-5300U is our recommended choice as it beats the Core 2 Duo E8400 in performance tests. Be aware that Core 2 Duo E8400 is a desktop processor while Core i5-5300U is a notebook one.
0. 65W. 65W. Lower is better. Detailed side by side comparison of Core 2 Duo E4400 vs Intel Pentium E5300 specs can be found in the Specifications section below. More detailed comparison of low level features of both microprocessors is located in the CPUIDs section .
Simple version: Core 2 Duo is dual-core. There are two 3.066 processors on one chip. Core 2 Quad is quad-core. There are four processors on one chip. The iMac uses the mobile version, i.e., same performance as any other Core 2 Duo at that clock speed but much lower wattage and heat output, and a bit more expensive. Core 2 Duo; Definition: Xeon is a variant of the Pentium microprocessor, designed for multiprocessing operations at large Databases and Internet Servers. Core 2 Duo is a dual-core processor based on the Pentium M microarchitecture and is designed to be the successor of the Core Duo microprocessor. Number of Cores: 2 to 6 cores: 2 cores: Bus Speed .
