At Computex 2022, AMD CEO Dr. Lisa Sui announced the AM5 platform associated with the Ryzen 7000 series of processors. However, while discussing specific details about the new Zen 4 and later platforms, AMD has caused confusion around the AM5 platform by quoting different power values to different groups. .. Ultimately, AMD is at various points in time, both as the highest nominal TDP supported by the platform and as the Power Package Tracking (PPT) rating, which is the absolute maximum power that the chip can draw under load. Estimated 170 watts. Needless to say, neither of these two claims was correct and needed to be corrected.
As First reported With Tom’s hardware crew, AMD has dealt with the turmoil and issued a statement proving the correct values. So the 170 watt TDP was right. On the other hand, the PPT value is actually 230 watts. This is 1.35 times the TDP rating and is common with AMD’s Ryzen processors.
The full text of AMD is below.
AMD wants to fix future AMD Socket AM5 socket power and TDP limits. AMD Socket AM5 supports up to 170 WTDP with PPT up to 230 W. TDP * 1.35 is the TDP v of AMD sockets from the “Zen” era. It is a standard calculation of PPT, and the new 170W TDP group is no exception (170 * 1.35 = 229.5).This new TDP group, alongside Ryzen’s today’s known 65W and 105W TDP groups, will significantly improve the computing performance of core CPUs with heavy computing workloads. AMD takes great pride in providing transparent and candid product features to the enthusiastic community. We take this opportunity to apologize for any errors that may have occurred in this topic and any subsequent confusion.
The overall increase in power specifications for the AM5 platform was not unexpected – some of the benefits of migrating to LGA sockets are additional pins for power supply – but this is ultimately AMD. New sockets and platforms will solve the set power problem of delivery. Of course, motherboard vendors will definitely pass this (successfully) on high-end boards, but 170W / 230W will be the baseline for motherboards that officially want to support high-end AM5 chips.
Now that we are in the dark silicon era, CPU power consumption has increased over the last few years. Individual CPU cores still consume only a modest amount of power (about 20W to 30W for high performance cores), but for high-end processors with 16 or more cores, the total power requirement grows rapidly. As a result, power limits are usually a limiting factor for highly multithreaded workloads, as the CPU must slow down the clock to stay within power range. Increasing the power limit of the platform will increase the headroom for keeping more cores clocked more often.
Note that AMD’s description today is about the AM5 socket, not the first Ryzen 7000 series chip to use it. AMD doesn’t necessarily have to take advantage of the full socket TDP right away, but for the MT performance reasons mentioned above, there are good reasons to take advantage of it. Therefore, officially, it is not yet known what the TDP of the high-end Ryzen 7000 processor will be. But informally, it’s not surprising to see the top chips approach 170 watts.
Finally, it seems necessary to expect the Ryzen 7000 family to remove its full TDP from the gate.according to Comments from AMD Spokespersons on RedditThe top TDP of the Ryzen 7000 series is actually 170 watts and the PPT reaches 230 watts.
