AMD clarifies their 5.5 GHz demo was running stock settings
AMD’s Robert Hallock and Frank Azor took part in PCWorld’s ‘The Full Nerd” interview where they answered some burning questions regarding the Computex keynote with Ryzen 7000 CPUs showcase.
Among the disclosure of new AM5 platform and 600-series motherboard details, AMD provided new info on Ryzen 7000 CPUs based on Zen4 architecture. Although the new series are not to release till September at least, people have been wondering what exactly did AMD want to (and not) tell to their fans.
One of such topics was the Ghostwire: Toyko game demo with 16-core engineering sample of Ryzen 7000 CPU running at 5 GHz+ frequency. Robert Hallock today confirmed this test did not involve any special cooling. AMD was actually using a 280 mm Asetek all-in-one liquid cooler for this demo. The CPU was running on an AMD engineering platform with 2x16GB DDR5-6000 CL30 memory.
More importantly, this sample was not overclocked. It was running stock frequency and surpassed 5 GHz with most of its threads. The frequency fluctuated between 5.2 to 5.5 GHz on multiple cores, but in the end, it will depend on the game. However, what AMD wants to say is that there was no overclocking involved and there was nothing special about this test or the CPU used.
Ian Cutress from TechTechPotato put all AMD claims on this demo in a single tweet:
AMD's Robert Hallock on the 5.5 GHz Demo in @PCWorld stream:
▶ AMD Reference Mobo
▶ 280mm AIO cooler
▶ 16 core prototype from April
▶ Plugged in, no OC
Natural freq of that CPU
▶ Most threads around 5.5, depends on scene/game
▶ 5.2-5.5 on all threads was common on the game

Furthermore, Hallock reconfirmed that the 170W claim on AMD Computex slides did refer to PPT (socket power), not TDP of an individual CPU. The primary reason behind increased PPT power for AM5 socket was to increase multi-core frequency, Robert explains. Higher PPT means higher TDP, so there is no doubt that it contributed to the higher frequency of the AMD Ryzen 7000 CPUs as seen in the gaming demo.
