The Intel Core 2 Duo T9800 was the top dual core CPU for laptops at the time of introduction. Later it was topped by the Core 2 Duo T9900 / X9100. Still the T9800 is a high end laptop CPU which is well suited for single and dual threaded applications.
Due to the high clock speed, the T9800 offers enough performance for demanding games (in 2009) and applications. On average, only faster dual cores (like the T9900 or fast Core i7) or Core i7 quad cores can be faster than the T9800.
The T9800 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 T9800 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)
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.
