The Intel Core i5 2537m processor is one of the newest sandy bridge processors that is meant to be used in ULV notebooks like Macbook Air and ultra books. This new processor has a TDP of just 17 watts and has two cores that can handle up to four threads at a time.
While the base clock speed is just 1.4GHz (to conserve power), the processor can automatically over clock itself to 2.3GHz under turbo mode. The 2537M also features an integrated Intel HD 3000 graphics, just like Core i5 2557m processor which we reviewed sometime back.
Compared to the Core i5 2467m processor, the 2537m scored about ~800 points less in the PCMark Vantage benchmark test. However, the 2557m processor came on top with its 10342 score. All of them were at least 3 times as powerful as the just released AMD A6 3400m processor.
