As of September 2010, Pentium E5800 is the last in series of Pentium-branded dual-core CPUs with 800 MHz Front Side Bus frequency. First references to this CPU appeared in September 2010, when Intel published processor's S-Spec and part numbers. According to preliminary specifications, the E5800 is based on Wolfdale-3M core, and has two cores with dedicated L1 caches, and 2 MB L2 shared between cores. The CPU utilizes Front Side Bus (FSB) interface to access memory and talk to peripheral devices. The FSB is clocked at 200 MHz, but, since the processor can transfer data 4 times during each bus clock, effective bus frequency is 800 MHz. Pentium E5800 operates at 3.2 GHz, and it's going to be the fastest Core-based microprocessor with 800 MHz FSB after official launch. The Pentium includes basic set of features - ability to run 64-bit programs and operating systems, protect data memory with the help of Execute Disable Bit feature, and use Virtualization technology to accelerate execution of applications and operating systems in virtual environments. The CPU fits 65 Watt thermal envelope, and works in socket 775 motherboards. The Pentium E5800 will be offered in both OEM and boxed versions.
