"Released roughly a year ago, the Celeron J4125 is two years newer than the Celeron J4105 in the Access3. The two chips, however, are very similar. Both are unthreaded, quad-core CPUs built on the 14nm process. The Celeron J4125 has a slight edge in processing speed, running at 2GHz to its predecessor's 1.5GHz base frequency and able to hit a burst frequency of 2.7GHz to the older chip's max of 2.5GHz. Even with the newer chip, the Access4 felt sluggish when attempting to navigate Windows. Lag was everywhere, from opening menus to switching apps. The simplest tasks require patience, and major multitasking is best avoided."
