The Intel® Core™ 2 Duo E6300 Processor is currently the bottom end flavor of the Intel® Core™ 2 Duo E6000 series of processor. Above this, lined up higher speed grade, from Intel® Core™ 2 Duo E6400, Intel® Core™ 2 Duo E6500 Intel® Core™ 2 Duo E6600, and Intel® Core™ 2 Duo E6700. Of course, the cream of the crop is the extreme edition, aptly branded as Intel® Core™ 2 Duo X6800, but this "E" CPU on the test bench is not within the league of "X". This processor may not look so attractive compared to the earlier Intel® Pentium® D-based processors when comparing clock frequency, but Intel is now trumpeting and singing a new song, instead of pure performance and power through rooftop high clock frequency, the direction is now thru performance per watt and they did it with in style only Intel can muster.

Currently, users are already enjoying the power of simultaneous computing found in earlier dual-core processor, the Intel® Pentium® D processor brings this power to the desktop. An Intel dual-core processor delivers consumer value by providing additional computing resources that expand the PC's capabilities and provide platform-level advancements for consumers in the form of higher throughput and simultaneous computing. With an Intel® Core™ 2 Duo processor, users may perform multiple tasks such as digital rendering and gaming all while running virus scan or other background tasks seamlessly, and they are doing it with less power consumption. It has great features for digital home computing, such as support for EM64T to enable the system to address more than 4GB of system memory and advance security functionality thru Execute Disable Bit that can prevent certain classes of malicious "buffer overflow" attacks when combined with a supporting operating system, and with lots of new features found only on CPUs based on Intel® Core™ microarchitecture.
