Intel Core i3-2367M vs Intel Core 2 Duo T9500

The Intel Core i3-2367M is a power efficient ULV (Ultra Low Voltage) processor for thin and light laptops. The base frequency of 1.4 GHz is relatively low and the CPU does not support Turbo Boost for automatic overclocking. Due to HyperThreading, the i7-2367M is able to handle 4 threads in parallel. Compared to similar clocked Celeron and Pentium models, the i3 features the faster HD 3000 graphics card and offers more enabled features (like Quick Sync). However, compared to the expensive i7 CPUs, the i3 lacks VT-d, Trusted Execution and VPro support.

Sandy Bridge is the evolutionary successor of the Arrandale architecture. The most notable improvements is the improved Turbo 2.0 (not used for the processing cores in the i3-2367M) and the integration of the graphics card into the 32nm CPU core.

The integrated Intel HD Graphics 3000 clocked at 350 or 1000 MHz (Turbo Boost). Due to the slower clock rate without the Turbo, compared to HD Graphics 3000 in 35W and 45W processors (usually clocked at 650 base speed in non LV processors), the performance should be noticeable lower.

The performance of the CPU should be a bit higher than a similar clocked Arrandale Core i3 ULV and therefore faster than the 1.33 GHz Core i3-380UM. The average performance of the CPU part should therefore be similar to the AMD A4-3300M.

The TDP of 17W (includes the integrated GPU and memory controller) allows the use of the 2367M CPU in small subnotebooks.

The Intel Core 2 Duo T9500 was a upper middle class dual core CPU for laptops at the time of introduction. It was intended to be used in the Santa Rosa platform due to the 800 MHz FSB. The T9550 is only slightly higher clocked but offers already a FSB1066.

Due to the relatively high clock speed and 6MB Level 2 cache, the T9500 offers enough performance for demanding games (in 2009) and applications. 

The T9500 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).
