The integrated Enhanced Speedstep is able to downclock the core dynamically as low as 1200 MHz to save power (in idle mode). Due to the Wide Dynamic Execution Technology, the core is able to simultaneously execute up to four instructions. The P8800 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. High end gamers should choose a higher clocked Dual Core instead (when using a high end GPU). 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).ĭue 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). It features 2.66 GHz and a shared level 2 cache of 3 MB. The Intel Core 2 Duo P8800 is a dual core processor for laptops. Therefore, even smaller laptops can use the Core i5. Just like most other Ivy Bridge dual-cores, the i5-3380M is rated at a TDP of 35 W. The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 650 MHz up to 1250 MHz with Turbo Boost, making it one of the faster variants. As a result, overall performance is about 5-10 % above the old i7-2640M. The performance of the Core i5-3380M is slightly above a similarly clocked Sandy Bridge processor due to the architectural improvements. Other new features are integrated PCI Express 3.0 and DDR3(L)-1600 support. The CPUs are produced in 22nm (versus 32nm Sandy Bridge CPUs) and are the first to introduce 3D transistors for increased energy efficiency when compared to similarly clocked Sandy Bridge processors. Ivy Bridge is an enhanced d ie shrink of the Sandy Bridge architecture with improvements on both GPU and CPU performance. As its predecessor Core i5-3360M, it offers a 3 MB 元-Cache. Each core offers a base speed of 2.9 GHz but can dynamically increase clock rates with Turbo Boost up to 3.4 GHz (for 2 active cores) and 3.6 GHz (for 1 active core). Due to Hyperthreading, the two cores can handle up to four threads in parallel leading to better utilization of the CPU. The Intel Core i5-3380M is a fast dual-core processor for laptops based on the Ivy Bridge architecture. Intel Core i5-3380M ► remove from comparison
