Intel 4th Gen Xeon Scalable “Sapphire Rapids”: up to 350W PL1, 3.7 GHz single-core boost

Hardware leaker YuuKi-AnS posted a screenshot featuring Intel unreleased data-center processor, codenamed Sapphire Rapids. 

The next-generation server chips a yet to be released by Intel later this year. The platform called Eagle Stream will host at least two Xeon data-center generations called Sapphire Rapids and Emerald Rapids. The former has been progressively delayed, but it now on track to launch later this year, possibly around the same time the company launches the consumer 13th Gen Core “Raptor Lake” series.

Similarly to Alder and Raptor Lake, Sapphire Rapids is based on Intel 7 (previously referred to as 10 nm Enhanced SuperFin) fabrication process. It will offer up to 56-cores and 112-threads, with maximum TDP of 350W. Such configuration specifically has been found on an engineering sample obtained by YuuKi.

This isn’t the first time an engineering sample of Sapphire Rapids-SP has been seen. Previously a different ES2 silicon was limited to 270W of power, but this chip has increased TDP to 350W (Power Limit 1) with PL2 set to 420W. It supposedly has a base clock of 1.9 GHz and boost of 3.3 GHz for Turbo Max. According to the data collected by HWINFO64 software, a single-core boost might reach as high as 3.7 GHz.

Based on this, one could conclude that we are looking at either Xeon Platinum 8476 or Platinum 8480, both of which expected to feature 56 cores and 112 threads. The CPU has been tested on Intel C741 “Emmitsburg” motherboard attached to 1TB of DDR5-(4800?) with CL40-39-38-76 timings.

ntel confirmed that Sapphire Rapids is on track to launch this year, but the company did not specify what month. The 4th Gen Xeon Scalable series are to be replaced by Emeralds Rapids next year. Intel already revealed its plans for 5th and 6th Gen Xeon series in February this year.
