Intel Core 2 Duo P8400 vs Intel Core 2 Duo T6500 vs Intel Core 2 Duo T6670

Intel Core 2 Duo P8400

► remove from comparison Intel P8400

The Intel Core 2 Duo P8400 is a dual core processor for laptops. It features 2.26 GHz and a shared level 2 cache of 3 MB. Due to the smaller cache (Core 2 Duo T-Models got usually 6 MB at this clock rate), the TDP is only 25 Watt (instead of the 35 Watt of the T-models).

The performance of the P8400 is on par with the fast Turion II Ultra with about 2.4 to 2.6 GHz. Modern demanding games like Supreme Commander may be limited by the CPU performance. High end gamers should choose a higher clocked Core 2 Duo (or Core i5 / i7).

The P8400 uses a Penryn (Montevina Update) core that features 2 integer units, 1 floating point unit, 1 load unit, and 1 store unit in a 14-stages long pipeline. Due to the Wide Dynamic Execution Technology, the core is able to simultaneously execute up to four instructions.

The integrated Enhanced Speedstep is able to downclock the core dynamically as low as 800 MHz to save power (in idle mode).

The Core 2 Duo P8400 can be used in a Socket P socket 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)

Intel Core 2 Duo T6500

► remove from comparison

The Intel Core 2 Duo T6500 is an entry level dual core processor for laptops. It is based on the Penryn core but offers only 2 MB level 2 cache and a slow clock rate of 2.1 GHz. Compared to the Core 2 Duo T6570, the T6500 does not offer Virtualization VT-x and is therefore aimed at consumer notebooks.

The performance should be suited for non demanding applications like office, internet, entry level video editing or image correction. CPU intense games may be limited by the power of the T6500.

Intel Core 2 Duo T6670

► remove from comparison

The Intel Core 2 Duo T6670 is an entry level laptop processor based on the Penryn core. It offers only 2 MB level 2 cache and a mediocre clock rate of 2.2 GHz. Compared to the similar T6600, the T6670 offers Virtualization VT-x and a higher maximum temperature of 105°C.
