Intel Core 2 Duo P8400 Mobiler SLB3R 2.267GHz 3MB L3 Sockel P

The Intel Core 2 Duo are 64 bit microprocessors of the 2nd Core generation. The mass market version with 2 processor cores are called Core 2 Duo. Due to drastically shortened pipeline technology and improved computing units, the Core 2 Duo provide up to 40% more performance at the same clock frequency. In addition, the power-saving function of the predecessors Pentium M and Intel Core has been integrated.

The Intel Core 2 Duo P8400 dual-core processor offers two processor cores with a shared Level 2 cache of 3 MB. Compared to the more powerful models, the P8400 only has half the Level 2 cache, but its power consumption is also lower at a maximum of 25 watts. The architecture of the processor is based on the Penryn core and is manufactured in 45nm.

The P8400 is very similar to the OEM version Core 2 Duo P7550, which came onto the market later.

For multimedia applications and undemanding games, the performance of the Intel Core 2 Duo P8400 should be sufficient. Compared to AMD, the performance should be on par with the fastest Turion II Ultra with 2.4 - 2.6 GHz. However, demanding gaming fans should rather go for higher clocked Core 2 Duo CPUs (>2.5 GHz).

The Penryn (Montevina Update) core offers 2 integer units, 1 floating point unit, 1 load unit and 1 store unit in a 14-stage pipeline. With Wide Dynamic Execution technology, the core can execute up to four full instructions simultaneously.

Thanks to Dynamic Acceleration (later called Turbo Mode), one core can overclock itself by one stage when the second is in idle mode.

The integrated Enhanced Speedstep can dynamically adapt the processor's clock frequency to the performance requirements. As a result, the CPU only runs at 800 MHz without load.

The Core 2 Duo P8400 fits into the Socket P (with 479 pins):

Socket P / Micro Flip-Chip Pin Grid Array (Micro-FCPGA) requires 479-pin surface mount Zero Insertion Force (ZIF) socket (mPGA479M socket) or Micro Flip-Chip Ball Grid Array (Micro-FCBGA) for surface mount (479-ball).
