AMD SmartShift : What Is It?
AMD SmartShift is a new technology that is being introduced with the new AMD Ryzen 4000 Mobile processor family.
It can be simply described as a smart power distribution technique, to dynamically improve CPU or GPU performance with a limited power budget.
How Does AMD SmartShift Work?
In a typical laptop, the CPU and GPU each have their own pre-defined power budget.
The CPU and GPU will individually adjust their power consumption according to the load, using less power for a longer battery life, but never exceeding their power budget even when there is a need for more performance.
AMD SmartShift changes that by simply doing away with the pre-defined power budget, and using a shared power budget instead.
When you are running CPU-intensive tasks, it lets the Ryzen CPU take up more of the power budget, improving its performance.
But when you start up a game, AMD SmartShift lets the Radeon GPU take up more of the power budget, for better gaming performance.
Ultimately, SmartShift lets you squeeze out more performance from the CPU and GPU for a limited power budget.
The Performance Impact
According to AMD, SmartShift will deliver up to 10% better gaming performance, and up to 12% better content creation performance.
