The problem with tile based deferred rendering is that both applications and APIs are really meant for immediate mode rendering.
In other word, you (as a graphic company) need to invest massive amount of work/money in a software driver capable of hiding the chip's deferred nature in a manner that do not break classical application (read: without visual artifact).
Reading some PoverVR Kyro review, you will find that the chip performed very well, but the greatest problem where the driver, which often caused visual artifact (as application and APIs were expecting conventional immediate mode render devices).
