The Intel Pentium P6200 is an entry level CPU for laptops. It clocks with 2.13 GHz and supports no TurboBoost for automatic overclocking. Furthermore AES instructions and hyperthreading are disabled. The CPU supports Enhanced Speedstep, but there may be some other power saving features disabled (as the Penryn - Pentium series had).
The P6200 is based on the Arrandale CPUs and therefore contains an integrated memory controller and Intel HD Graphics graphics card (both manufactured in 45nm, the CPU in 32nm). The also called GMA HD graphics in the CPU is clocked at 500MHz and is able to overclock to 667MHz due to Turbo Boost (GPU only).
The performance of the CPU is a bit limited due to the low clock rate and the missing Turbo Boost and Hyperthreading. Still the performance per GHz should be a bit better than similar clocked Core 2 Duo, because of the integrated memory controller and small improvements in the core.
