Intel Core 2 Duo T9900 vs Intel Core 2 Duo T9550 vs Intel Core 2 Duo T6400

Intel Core 2 Duo T9900

► remove from comparison Intel T9900

The Intel Core 2 Duo T9900 is the theoretical successor of the Core 2 Extreme X9100 (which also clocks at 3.06 GHz) that uses less power due to the modern stepping and the Enhanced Halt State (C1E). The only advantage of the X9100 is the free multiplikator (which allows easy overclocking of the CPU).

The T9900 is a fast dual core CPU for laptops which features 6 MB of shared level 2 cache and a TDP of 35 Watt. Due to the high clock speed, modern games (in 2009) should not be limited by the CPU speed. For single threaded applications it is one of the fastest CPUs for laptops (only beaten by the new Core i7 with enabled Turbo mode). 

The T9900 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 T9900 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 T9550

► remove from comparison Intel T9550

The Intel Core 2 Duo T9550 was the middle class dual core CPU for laptops at the time of introduction. It is similar to the Core 2 Duo P9600 except for the higher TDP of 35 versus 25 Watt.

Due to the relatively high clock speed and 6MB Level 2 cache, the T9550 offers enough performance for demanding games (in 2009) and applications. 

The T9550 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).

Intel Core 2 Duo T6400

► remove from comparison

The Intel Core 2 Duo T6400 is an entry level dual core processor for cheap laptops. It is based on the Penryn core but offers only 2 MB level 2 cache and a slow clock speed of 2 GHz. The performance should be sufficient for office and other casual tasks but high level gaming and HD video editing for example could be limited by the CPU performance.
