AMD’s Ryzen 6000 processors arrive in the spring with an improved architecture that focuses on energy efficiency. This series comes with PMF, a technology that automates energy management to optimize performance or endurance depending on the activity.

AMD announced at CES 2022 its latest addition, the Ryzen 6000 line of processors based on the Zen 3+ architecture, and the first computers equipped with this novelty should not delay any longer. Without really revolutionizing the CPU part – AMD plans with Zen 3+ to increase the cache in particular – the focus will be on the GPU part which goes under RDNA2 architecture, but also on better energy efficiency.
The PMF for better autonomy
To this end, the manufacturer has unveiled a new technology called PMF (Power Management Framework, or energy management system if we had to offer a translation) which appears very interesting on paper. In practice, it is similar to the different Windows battery management options that we already know (economy, balanced or performance), but would act in a more “intelligent” way. If for the moment it is necessary to manually select the different profiles that you want to apply, with the PMF, everything would become automatic, depending on the applications in use. This should therefore make life easier for users and improve the autonomy of computers.

Depending on the processor resources required, the computer will manage the appropriate profile in the background. While browsing the internet or in office automation for example, one can imagine that the PMF will activate the eco mode while the launch of photo or video editing software will activate maximum performance. This should also be handy for PCs. gamingon which we must activate the turbo mode before each gaming session to obtain the best performance, then deactivate it afterwards if we do not want the ventilation to run at full speed.
We also wonder how AMD and its OEM partners will work together to integrate this technology, because currently, it is often manufacturer software that makes it possible to change the energy profile, especially on gaming models. We can in any case deactivate the PMF if necessary, in order to keep control over the different profiles.
While waiting for our first tests of PCs equipped with Ryzen 6000 processors, we have concocted a short summary of the new features to come with this promising generation.
