Intel Core 2 Duo T6770 vs Intel Core 2 Duo T6600 vs Intel Core 2 Duo T9900

Intel Core 2 Duo T6770

► remove from comparison

The Intel Core 2 Duo T6670 is a laptop processor based on the Penryn core. It offers only 2 MB level 2 cache and is therefore slower than other 2.3 GHz clocked Core 2 Duo CPUs.

Intel Core 2 Duo T6600

► remove from comparison

The Intel Core 2 Duo T6600 is an entry to mid-range dual core processor for laptops. It is based on the Penryn architecture, but features only 2 MB level 2 cache and a mediocre clock rate of 2.2 GHz. Compared to the similar T6670, the T6600 does not feature Virtualization features in hardware and is speced at a lower maximum temperature.

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 T6600.

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).
