As a reminder: The two new models are called A275 and A475. There hasn´t been a ThinkPad A-Series in recent years. Long ago, there was a Thinkpad A-Series, but those were the workstations models (such as the ThinkPad A31p). These days, the ThinkPad workstation line is the P-Series, so its safe to assume these new A-Series ThinkPads are not long the IBM ThinkPad A-Series of the old times. This opens the room for the speculation that these new models will be use AMD-CPUs, which would fit with the name A-Series. Also, the ending with the number five was traditionally reserved for AMD ThinkPads (such as the
ThinkPad E555).
