Intel Core 2 Duo SL9400 vs Intel Core 2 Duo T8300 vs Intel Core 2 Duo P8400

Intel Core 2 Duo SL9400

► remove from comparison Intel SL9400

The Core 2 Duo SL9400 is a power saving low voltage CPU for thin and light laptops. It offers a good performance for the 1.86 GHz clock rate, as it features the full 6 MB level 2 cache of the used Penryn core.

Intel Core 2 Duo T8300

► remove from comparison

The Intel Core 2 Duo T8300 was at the time of announcement a fast dual-core CPU for laptops with 3 MB level 2 cache. It is based on the Penryn core with all features enabled (but without the full 6MB level 2 cache). The later announced Core 2 Duo P7450 was cheaper and used less power.

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)
