Net-net, we expect you’ll see lower desktop voltages, around 1.2V, for the core(s) actively handling such tasks. These cases tend to make regular requests for a higher boost state, but their intermittent nature would fall below the threshold of the activity filter. Example test cases might include: video playback, game launchers, monitoring utilities, and peripheral utilities. The changes primarily arrive in the form of an “activity filter” that empowers the CPU boost algorithm itself to disregard intermittent OS and application background noise. Today we’re announcing that AGESA 1003ABBA carries firmware-level changes designed to do just that. While many of you were happy with the effect of the software changes, some of you were still grappling with cases where the CPU was a bit overzealous with boost. The goal was to make the processor more relaxed at the desktop, but poised to react for serious workloads. In late July, we implemented a series of software changes that would help the processor ignore requests for voltage/frequency boost from lightweight applications. We do not expect that the improvements that have been made in boost frequency for AGESA 1003ABBA will have any impact on the lifetime of your Ryzen processor. While AGESA 1003AB contained changes to improve system stability and performance for users, changes were not made for product longevity reasons. We perform extensive engineering analysis to develop reliability models and to model the lifetime of our processors before entering mass production. In addition, we do want to address recent questions about reliability. It is fully expected that if users run a workload like Cinebench, which runs for an extended period of time, the operating frequencies may be lower than maximum throughout the run. PCMark 10 is a good proxy for a user to test the maximum boost frequency of the processor in their system. Ensuring your system has adequate thermal paste reliable system cooling the latest motherboard BIOS reliable BIOS settings/configuration the latest AMD chipset driver and the latest operating system can enhance your experience.įollowing the installation of the latest BIOS update, a consumer running a bursty, single threaded application on a PC with the latest software updates and adequate voltage and thermal headroom should see the maximum boost frequency of their processor. Our processors perform intelligent real-time analysis of the CPU temperature, motherboard voltage regulator current (amps), socket power (watts), loaded cores, and workload intensity to maximize performance from millisecond to millisecond. Going forward, it’s important to understand how our boost technology operates. Additional information on boost frequency in the 3rd Gen AMD Ryzen Processors can also be obtained from this separate blog update. These improvements will be available in final BIOSes starting in about three weeks’ time, depending on the testing and implementation schedule of your motherboard manufacturer. AMD Wraith Prism and Noctua NH-D15S coolers.AMD Reference Motherboard (AGESA 1003ABBA beta BIOS).We used the following test system in our analysis: The actual improvement may be lower or higher depending on the workload, system configuration, and thermal/cooling solution implemented in the PC. Our estimation of the benefit is broadly based on workloads like PCMark 10 and Kraken JavaScript Benchmark. Across the stack of 3rd Gen Ryzen Processors, our internal testing shows that these changes can add approximately 25-50MHz to the current boost frequencies under various workloads. These changes are now being implemented in flashable BIOSes from our motherboard partners. We’ve also been exploring other opportunities to optimize performance, which can further enhance the frequency. Starting with our commitment to provide you an update on processor boost, our analysis indicates that the processor boost algorithm was affected by an issue that could cause target frequencies to be lower than expected. The first two changes will be arriving in BIOSes based on AGESA 1003ABBA, and we are planning to make the SDK public on with a target release date of September 30. Today we have some important updates for you concerning processor boost behavior, desktop idle behavior, and a new monitoring SDK. Hello, everyone! We’re delighted by your support and the strong momentum of 3rd Gen AMD Ryzen processors in the marketplace, and we continue to watch your feedback closely.
