AMD introduced the Ryzen 4000 “Renoir” series OfUs earlier this year, and in addition to performance and power improvements, the company introduced an interesting TDP management feature called SmartShift. For devices with both AMD APU and discrete graphics cards, SmartShift allows the system to dynamically reallocate thermal design power consumption for both chips based on actual workload.
For original equipment (OEM) manufacturers, however, SmartShift depends on synergies in several ways, including processor selection, thermal system layout, and other platform-level features.
In other words, even if the manufacturer chooses the same AMD Ryzen 4000 APU processor, there is no guarantee that they will support SmartShift.
As a result, so far, only one model has supported AMD SmartShift Dynamic TDP tuning, dell’s G5 15 SE gamebook.
Even more embarrassingly, Frank Azor, the chief architect of AMD’s game solutions, recently confirmed on Twitter that it is also the only laptop to support the feature in 2020.
In addition to the comments on Twitter, Frank Azor revealed the same information during interviews with PCWorld and the Full Nerd podcast.
The reason is that it takes about a year for manufacturers to develop a laptop, and smartShift’s technical requirements mean that vendors must plan for support for this feature as early as possible.
Dell was able to differentiate itininly in 2020 because the company had developed the SmartShift program from an early age.
By 2021, however, more OEMs are expected to announce SmartShift technology that supports the AMD Ryzen 4000 APU platform.
