Intel Pentium U5600 vs Intel Pentium P6300

Intel Pentium U5600

The Intel Pentium U5600 is an entry level CPU for thin and light laptops. It is based on the Arrandale core (Core i3/i5) but Turbo Boost (for the CPU), Hyper-Threading, Virtualization, Trusted Execution, and AES functions are disabled. Due to the slow clock speed, the U5600 is only sufficient for non demanding applications.

The Arrandale Pentium CPU features the integrated Intel HD Graphics graphics card which is clocked at 166-500 MHz (due to Turbo Boost). Furthermore, the CPU also features an integrated memory controller that supports up to 8 GB of DDR3-800 main memory.

Intel Pentium P6300

The Intel Pentium P6300 is an entry level CPU for laptops. It clocks with 2.26 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 P6300 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.
