We’ve encountered an interesting and questionable rumor regarding AMD’s Ryzen 7000 “Dragon Range” mobility processors. According to a reputed tipster on the Chiphell forums, the Ryzen 7045 series CPUs don’t have a power ceiling by default (questionable). At similar clock speeds, the single-core performance of these Zen 4 chips is on par with Intel’s 13th-Gen Raptor Lake offerings. However, it’s the power efficiency of these parts comes into play here.
Update: It looks like the source is talking about Intel’s Xeon WS CPUs based on the Sapphire Rapids design.
The Ryzen 7000 notebook processors can be overclocked quite eloquently. The resulting power consumption, however, can be over the top. The source reports peak power draws of over 700W for the CPU alone, and you’d need a quality motherboard for reliable operation. At stock, the Ryzen 9 7945HX has an adjustable TDP of 55-75W and a peak power draw of around 100W.
The Zen 4 cores on Dragon Range sip over 6W of power by default. This figure can go as high as 10W per core upon overclocking. While these figures are more reasonable, the 700W number sounds too far-fetched. We’ll have to wait and see how the higher-end notebooks tackle overclocking on these desktop-grade CPUs.
