The Intel Core i5-2537M is power efficient ULV (Ultra Low Voltage) processor for thin and light laptops. The base frequency of 1.4 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 i5-2537M is able to handle 4 threads in parallel.
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 integrated Intel HD Graphics 3000 clocked at 350 or 900MHz (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 2537M CPU in small subnotebooks.
