Intel Core 2 Duo T9400 vs Intel Core 2 Duo T6570 vs Intel Core 2 Duo P8400

Intel Core 2 Duo T9400

► remove from comparison Intel T9400

The Intel Core 2 Duo T9400 was a uppder middle class dual core CPU for laptops, at the time of introduction. It is similar to the Core 2 Duo P9500 except for the higher TDP of 35 versus 25 Watt).

Due to the relatively high clock speed and 6MB Level 2 cache, the T9400 offers enough performance for most demanding games (in 2009) and applications.

The T9400 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 T6570

► remove from comparison

The Intel Core 2 Duo T6570 is an entry level dual core processor for laptops. It is based on the Penryn core but offers only 2 MB level 2 cache and a slow clock rate of 2.1 GHz. Compared to the Core 2 Duo T6500, the T6570 offers Virtualization VT-x and is therefore aimed at business notebooks.

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 T6570.

Intel Core 2 Duo P8400

► remove from comparison Intel P8400

The Intel Core 2 Duo P8400 is a dual core processor for laptops. It features 2.26 GHz and a shared level 2 cache of 3 MB. 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).

The performance of the P8400 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 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. 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).

The Core 2 Duo P8400 can be used in a Socket P socket with 479 pins: Socket P / Micro Flip-Chip Pin Grid Array (Micro-FCPGA) requires 479-pin surface mount Zero Insertion Force (ZIF) socket (mPGA479M socket) or Micro Flip-Chip Ball Grid Array (Micro-FCBGA) for surface mount (479-ball)
