shows this in a chart where Zen 4 SKUs have the highest W/mm 2.
To prove how much cooler the Raptor Lake CPUs run, Enthusiast Citizen also showcased an engineering sample of a Core i7-13700K running at a sustained 5.3 GHz on all P-cores while coming around 81 C.Īssuming these readings are true, the question is: Why do the Zen 4 processors produce so much heat? Leaker might have some answers for us.įirst, the Zen 4 chips are not only smaller than the Zen 3 parts but also pack considerably more transistors, resulting in a significantly increased heat output per mm 2. On the other hand, the Intel Raptor Lake Core i9-13900K allegedly produces a much lower 82 C while consuming 40 W more at 270 W. Substantiating Enthusiast Citizen’s report, Wccftech mentions hearing from one of their sources that the heat output of the AMD Ryseries CPUs stands between 92-94 C even with a “high-end 360 mm AIO liquid cooler” in AIDA64. The 6-core Ryzen 5 7600X also doesn’t fare any better according to the leaker as it shoots up to 90 C while consuming 120 W. As the chip produces 95 C under load, the leaker maintains that the Zen 4 flagship will reach thermal threshold and throttle to less than 5 GHz at 230 W. Posting over at Bilibili, Enthusiast Citizen reports that the Ryzen 9 7950X will lose to Intel Raptor Lake in multi-core “with no suspense”. But, according to Chinese hardware leaker Enthusiast Citizen, the performance of the Zen 4 CPUs comes at a huge thermal cost. The CPUs offer substantial performance improvements over their predecessors while being much smaller. The series which include the Ryzen 9 7950X (16 cores/32 threads), the Ryzen 9 7900X (12 cores/ 24 threads), the Ryzen 7 7700X (8 cores/ 16 threads), and the Ryzen 5 7600X (6 cores/12 threads).
AMD took the wraps off the Zen 4 Ryzen 7000 CPUs on August 29.
