The base clockspeed of this chip seems rather low, this could be a mistake or related to this being an early engineering sample. The Boost clock is 2.5GHz though. The N4200 has a 6W TDP and is capable of playing back 4K video, but there will also be more powerful versions with a TDP ranging up to 10W.
These low power consuming SoCs are going to replace Cherry Trail and Braswell family of chipsets that you find in tablets and 2-in-1 machines. Despite the fact that Apollo Lake chipsets are going to be manufactured on the same 14nm manufacturing process, these will feature Goldmont CPU cores compared to Intel’s Airmont cores present in Cherry Trail chipsets. A 30 percent increase in performance is also expected, and since Intel has made Apollo Lake thoroughly efficient, it has been stated that such SoCs will be able to deliver 15 percent increase in battery life.Via: WCCF Tech
