The integrated Enhanced Speedstep is able to downclock the core dynamically as low as 800 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 P8400 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 Core 2 Duo (or Core i5 / i7). Modern demanding games like Supreme Commander may be limited by the CPU performance. The performance of the P8400 is on par with the fast Turion II Ultra with about 2.4 to 2.6 GHz. 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). It features 2.26 GHz and a shared level 2 cache of 3 MB. Types, maximum amount and channel quantity of RAM supported by Core 2 Duo E8400 and Phenom X4 9750 (125W).ĭepending on the motherboards, higher memory frequencies may be supported.The Intel Core 2 Duo P8400 is a dual core processor for laptops. Virtual machine speed-up technologies supported by Core 2 Duo E8400 and Phenom X4 9750 (125W) are enumerated here. AES-NIĬore 2 Duo E8400 and Phenom X4 9750 (125W) technologies aimed at improving security, for example, by protecting against hacks. You'll probably need this information if you require some particular technology. Technological solutions and additional instructions supported by Core 2 Duo E8400 and Phenom X4 9750 (125W). Some can even double their declared thermals given that the motherboard allows to tune the CPU power parameters.
Note that power consumption of some processors can well exceed their nominal TDP, even without overclocking.
Useful when planning a future computer configuration or upgrading an existing one. Information on Core 2 Duo E8400 and Phenom X4 9750 (125W) compatibility with other computer components: motherboard (look for socket type), power supply unit (look for power consumption) etc. These parameters indirectly say of CPU speed, though for more precise assessment you have to consider their test results. Core 2 Duo E8400 and Phenom X4 9750 (125W) basic parameters such as number of cores, number of threads, base frequency and turbo boost clock, lithography, cache size and multiplier lock state.
