The 45nm processor spec goes mobile with the Core 2 Duo P8400. You get top end notebook performance while drawing only 25W. Lower power means lower heat and longer battery life without taking a performance hit. Intel was also able to pack more features into the chip. This is boosted by the Intelligent Power Capability which manages CPU power loads to further increase battery life.
L2 cache has been bumped to 3MB and the Front Side Bus has been pushed to 1066MHz. They also boosted memory access and execution speed with the Wide Dynamic Execution and Smart Memory Access. These combine to let the processor compute more instructions with more data per clock cycle. You'd better watch out those in game enemies will be shooting back faster now.
The Advanced Digital Media Boost feature has been enhanced with the addition of the SSE4 instruction set and Intel HD Boost. This will give your entertainment experience a boost with better audio and video processing. It will also help with speech recognition, engineering and scientific applications. Perhaps most important of all will be the boost to security with increased encryption power and speed.
Specialized Dual-core Microarchitecture
The Intel Core 2 Duo processor includes two execution cores in a single physical package to enable execution of parallel threads or applications on separate cores with dedicated CPU resources. The results enable outstanding dual-core performance and greater system response when running multi-threaded or multiple demanding applications simultaneously. The innovative 45nm dual-core technology optimizes thermal performance for reduced power consumption and noise.
Intel Centrino 2 Duo Mobile Technology
Intel Centrino 2 Duo mobile technology has just gotten a mobility upgrade with the new Intel Core 2 Duo mobile processor. Its advanced capabilities provide twice the multitasking performance with improved energy efficiency for enhanced battery life so you get the benefits of a powerful dual-core PC plus all the benefits of mobility.
Intel Extended Memory 64 Technology (Intel EM64T)
Intel EM64T provides an enhancement to Intel 32-bit architecture by enabling the mobile processor platform to access larger amounts of memory. With appropriate 64-bit supporting hardware and software, platforms based on an Intel processor supporting Intel EM64T can enable use of extended virtual and physical memory.
Enhanced Intel SpeedStep Technology (EIST)
EIST allows the system to dynamically adjust processor voltage and core frequency to decrease average power consumption and average heat production. Combined with existing power saving features, EIST may provide an excellent balance between providing power when you need it and conserving power when you don’t.
Execute Disable Bit (EDB)
Intel's Execute Disable Bit function can prevent certain classes of malicious "buffer overflow" attacks when combined with a supporting operating system. Execute Disable Bit allows the processor to classify areas in memory where application code can execute and where it cannot. When a malicious worm attempts to insert code in the buffer, the processor disables code execution, preventing damage or worm propagation.
Intel Virtualization Technology (Intel VT)
With Intel VT, one hardware platform functions as multiple "virtual" platforms. For business, Intel VT offers improved manageability, limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions. In the home, Intel VT allows creating unique user environments for multiple family members using the same platform simultaneously.
