Mobile Celeron P4500 is the first dual-core Celeron-branded microprocessor built on 032 micron process. Like all mobile Core i3 and i5 microprocessors, the Celeron is based on Arrandale core, which replaces Front Side Bus interface with integrated memory controller and Direct Media interface. The microprocessor has two cores integrated on a single die, while other package components - the memory controller, PCI Express interface and graphics controller, are located on a separate die. Each core incorporates 64 KB level 1 cache and 256 KB level 2 cache. The processor also has 2 MB shared level 3 cache. Basic features of this CPU are 64-bit instructions, Virtualization technology, and SIMD extensions up to SSE4. The Mobile Celeron P4500 is fabricated in micro-PGA package, and works in socket 988 motherboards. Currently, the P4500 is supported by Mobile Intel HM55, HM57 and QM57 Express Chipsets. As of beginning of May, 2010, Celeron P4500 microprocessors are shipped in Lenovo ThinkPad Edge line of notebooks, HP ProBook-series (4520s, 6450b, etc), Dell Vostro 3500 and 3700, and notebooks from other manufacturers.
