Intel has been providing RKL-S docs for some time. Recently an ES has been spotted in Geekbench. Intel will likely release RKL-S at least as a halo-product to beat the AMD's Zen 3 attempt.

Reportedly, Zen 3 achieves a 15-20% higher perf. A 5+GHz RKL-S based on Willow Cove should beat that in general ST. However, that slowish L3 and hellish TDP remain a question.
