Intel Core 2 Duo SU9400 vs Intel Core i5-2467M vs Intel Core 2 Duo P7570
Intel Core 2 Duo SU9400
► remove from comparisonThe Intel Core 2 Duo SU9400 is a power efficient subnotebook processor based on the Penryn 3M core. It features all functions of the Penryn core, like Virtualization (VT-x), Trusted Execution and Speedstep. Due to the low core clock, the performance is limited.
Intel Core i5-2467M
► remove from comparison
The Intel Core i5-2467M is power efficient ULV (Ultra Low Voltage) processor for thin and light laptops. The base frequency of 1.6 GHz is relatively low, but due to Turbo Boost 2.0, the CPU may clock up to 2.3 GHz (one core loaded, 2GHz with both cores loaded). However, this is depending on the cooling and power consumption of the laptop. Due to HyperThreading, the i5-2467M is able to handle 4 threads in parallel. Compared to the slightly slower i5-2537M, the 2467 offers a faster base speed (1.6 vs 1.4GHz).
Sandy Bridge is the evolutionary successor of the Arrandale architecture. The most noteable improvements is the improved Turbo 2.0 and the integration of the graphics card into the 32nm CPU core. The 2467M offers not all features of the Sandy Bridge core, e.g. VPro, VT-d or Trusted Execution are not enabled.
The integrated Intel HD Graphics 3000 clocked at 350 or 1150MHz (Turbo Boost). Due to the slower clock rate, compared to other HD Graphics 3000 (usually 650-1100/1300MHz 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 i5. Therefore, the performance should be similar to a Core i7-680UM / Core i3-330M.
The TDP of 17W (includes the integrated GPU and memory controller) allows the use of the 2467M CPU in small subnotebooks.
Intel Core 2 Duo P7570
► remove from comparisonThe Intel Core 2 Duo P7570 is a dual core processor for laptops. It features 2.26 GHz and a shared level 2 cache of 3 MB. It is an OEM CPU and similar to the Core 2 Duo P8400 (additional Trusted Execution Technology) and Core 2 Duo P7550 (lacks Virtualization VT-x).
The performance of the P7570 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 P7570 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).
