For 104 GC cores, they must be running at <=2GHz to get such a low score.
Its possible they will be slow, to fit in a 370 watt envelope. Thats 53 watts per 8 cores, less than any retail Alderlake. And thats 56 cores, they may be at 52.
At any rate, we have to wait for official reviews, but the one above looks pretty close, and it says Sapphire rapids will get killed in performance comparisons and generate a lot of heat and use a lot of power. Read the clip he copied from that review.
Edit: I just copied it
"Although this is an ES chip and we expect performance to improve significantly for the Sapphire Rapids-SP chip in the QS state, the final chip may still be only competitive against AMD's EPYC Milan parts while it will be launching at the same time when AMD will come out guns blazing with its next-generation EPYC Genoa 7004 CPUs. With such high power draw and not enough performance at hand, it looks like Intel will be getting a serious beating in the server segment by AMD, something that has been the case over the past few generations"
