Intel Core 2 Duo P7550 vs Intel Core 2 Duo P8600 vs Intel Core 2 Duo T9900

Intel Core 2 Duo P7550

► remove from comparison

The Intel Core 2 Duo P7550 is a dual core processor for laptops. It features 2.26 GHz and a shared level 2 cache of 3 MB. It is an OEM CPU and similar to the Core 2 Duo P8400 (additional Trusted Execution Technology, and VT-x) and Core 2 Duo P7570.

The performance of the P7550 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 P7550 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).

Intel Core 2 Duo P8600

► remove from comparison Intel P8600

The Intel Core 2 Duo P8600 is a dual core processor for laptops. It features 2.4 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).

Due to the relatively high clock speed, modern games (in 2009) should not be limited by the CPU speed (in conjunction with a middle class graphics card). High end gamers should choose a higher clocked Dual Core instead (when using a high end GPU). Compared to the fastest Turion II Ultra M640, the P8600 should be still faster.

The P8600 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 1200 MHz to save power (in idle mode).

The Core 2 Duo P8600 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 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).
