The Intel Core 2 Duo T9500 was a upper middle class dual core CPU for laptops at the time of introduction. It was intended to be used in the Santa Rosa platform due to the 800 MHz FSB. The T9550 is only slightly higher clocked but offers already a FSB1066.
Due to the relatively high clock speed and 6MB Level 2 cache, the T9500 offers enough performance for demanding games (in 2009) and applications.
The T9500 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 to save power (in idle mode).
The Core 2 Duo SP9300 is a power efficient (25W TDP) dual core CPU for laptops. Compared to other Core 2 Duo with 2.26 GHz, the SP9300 features the full 6 MB level 2 cache of the Penryn core. Usually 3MB are enabled for 25 W CPUs at this clock range (e.g. P8400). Therefore, the performance is a bit better than similar clocked C2D CPUs.
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)
