Intel Core 2 Duo SL9600 vs Intel Core 2 Duo SP9600 vs Intel Core 2 Duo P7450
Intel Core 2 Duo SL9600
► remove from comparisonThe Intel Core 2 Duo SL9600 is a low power laptop processor for small and slim laptops. It features the full 6 MB level 2 cache and all features of the Penryn core (e.g. VT-x and Trusted Execution). Due to the large cache, the CPU shows a good performance for the small clock rate. However, in the MacBook Air, the CPU throttled very often, leading to the slower benchmarks in our database.
Compared to other Core 2 Duo models, the C2D SL9600 only supports the socket BGA956 and is soldered in the MacBook Air models.
Intel Core 2 Duo SP9600
► remove from comparison
The Intel Core 2 Duo SP9600 is a upper middle class dual core CPU for laptops, at the time of introduction. The SP9600 is basically a Core 2 Duo P9500 produced in a BGA Package for direct soldering on the mainboard. The package of the chip is therefore smaller and more suited for thin laptops. The power consumption is similar to the P9500.
Due to the relatively high clock speed and 6MB Level 2 cache, the SP9600 offers enough performance for most demanding games (in 2009) and applications.
The SP9600 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 P7450
► remove from comparisonThe Intel Core 2 Duo P7450 is a dual core processor for laptops. It features 2.1 GHz and a shared level 2 cache of 3 MB. It is based on the 45nm Penryn core, but Trusted Execution and Virtualization (VT-x) are disabled.
The P7450 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).
