Sapphire Rapids sample exposures: 56 cores and 112 threads, 350W TDP, PL2 up to 420W

Intel’s next-generation server processor, Sapphire Rapids, was originally said to debut at the end of last year. However, after the delay, the current rumor is that it will be launched in the third quarter of this year, but various news about Sapphire Rapids has begun to flow out recently, and I believe it is really not far from the release.

@yuuki_ans recently released a screenshot of the CPU information of a 56-core ES from Sapphire Rapids, which is similar to consumer-grade Alder Lake and Raptor Lake. Sapphire Rapids uses Intel 7 process, which is the original 10nm Enhanced SuperFin process. Unlike the previously exposed Sapphire Rapids sample, the TDP of the previous ES processor was only 270W, while the TDP of this one was increased to 350W, while the PL2 can reach 420W. According to HWINFO software, the maximum power consumption of the processor can reach 764W, which is estimated to be the highest instantaneous power consumption.

According to the screenshot, the maximum turbo frequency of this sample of Sapphire Rapids from 1 to 28 cores can reach 3.7GHz, and the maximum turbo frequency of all cores is 2.8GHz. The turbo frequency will decrease when AVX2 and AVX-512 are under load, and the base frequency is 1.9GHz. It is speculated that this processor may be Xeon Platinum 8476 or Platinum 8480, both of which are expected to be 56 cores and 112 threads. It is installed on the Intel C741 motherboard, code-named Emmitsburg. From the software, we can see that this platform is equipped with 1TB of DDR5 memory, the timing is 40-39-38-76, and the memory frequency is speculated to be 4800MHz.

Sapphire Rapids will debut this year as the fourth-generation Xeon Scalable processor, according to Intel’s roadmap, it will be replaced by Emeralds Rapids processors next year. Intel actually announced the roadmaps for the 5th and 6th generation Xeon Scalable processors in February this year.
