Intel Core 2 Duo P7570 vs Intel Core 2 Duo SL9380 vs Intel Core 2 Duo SP9300
Intel Core 2 Duo P7570► remove from comparison
The Intel Core 2 Duo P7570 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 Core 2 Duo P7550 (lacks Virtualization VT-x).
The performance of the P7570 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 P7570 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 SL9380► remove from comparison
The Core 2 Duo SL9380 is a power saving low voltage CPU for thin and light laptops. It offers a good performance for the 1.8 GHz clock rate, as it features the full 6 MB level 2 cache of the used Penryn core. Compared to the SL9400, the SL9380 offers only an FSB with 800 MHz clock rate (instead of 1066) and exactly 1.8 GHz (SL9400 1.86).
Intel Core 2 Duo SP9300► remove from comparison
The Core 2 Duo SP9300 is a power efficient (25W TDP) dual core CPU for laptops. Compared to other Core 2 Duo with 2.26 GHz, the SP9300 features the full 6 MB level 2 cache of the Penryn core. Usually 3MB are enabled for 25 W CPUs at this clock range (e.g. P8400). Therefore, the performance is a bit better than similar clocked C2D CPUs.
