It runs at a base speed of 1.8GHz but automatically overclocks to 2.8GHz under turbo boost mode. Like the Core i5 3317U, it is manufactured using 22nm technology and has TDP of 17 watts.
The Core i5 3427U comes with integrated Intel HD 4000 graphics is clocked at 350MHz (1150MHz under turbo boost mode) and 3MB L3 cache. In the PCMark Vantage benchmark, it got a massive 13500 score, which is double of what we got in the Intel Core i5 3317U review.
