Intel Core 2 Duo T9550 vs Intel Core 2 Duo T6600 vs Intel Core 2 Duo P7550
Intel Core 2 Duo T9550
► remove from comparison
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 T6600
► remove from comparisonThe 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 P7550
► remove from comparisonThe 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).
