In today's usage environment, processor speed alone is not enough to ensure a great experience. The advanced dual core Intel Pentium D 945 processor features two 65nm processor cores each running at 3.4GHz with integrated 2MB L2 cache. The cutting edge 65nm manufacturing process significantly reduces power consumption and improves thermal performance. Users today have high expectations for their PCs and want the most productivity and enjoyment from their PCs when running multiple applications simultaneously. The 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. Featuring Intel Extended Memory 64 Technology, Enhanced Intel SpeedStep Technology and Execute Disable Bit, the Intel Pentium D 945 processor delivers outstanding desktop and workstation computing experiences."
Dual-Core Processing with 2x2MB L2 CacheIntel dual-core Pentium D 945 processors have two complete processor cores in one physical package running at the same frequency. The cores share the same interface with chipset and memory, but each core has its own set of registers and cache for truly parallel computing. Each processor core has its own 2MB L2 Cache (4MB total) enabling improved overall system performance by allowing each core to have faster access to larger amounts of the most often used area.
Intel Extended Memory 64 Technology (Intel EM64T)Intel EM64T provides an enhancement to Intel 32-bit architecture by enabling the desktop 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.
