Intel has the palm and sunny cove uarchs completed years ago and another few improvements on them.
Sunny features 20% more instruction units while other things are improved even more.It will be easily 20% faster per clock than skylake in anything that benchmarking sites are focusing on.Clocks will very probably be quite a bit lower than commetlake thou.
Sunny is intel's 10nm second iteration it was supposed to come out 2017 (to counter ZEN1) but there was no need to so they didn't release it.
Sunny Cove (SNC), the successor to Palm Cove, is a high-performance 10 nm x86-64 core microarchitecture designed by Intel for an array of server and client products, including Ice Lake (Client), Ice Lake (Server), Lakefield, and the Nervana NNP-I. The microarchitecture was developed by Intel's...

"Sunny Cove was originally unveiled by Intel at their 2018 architecture day. Intel originally intended for Sunny Cove to succeed
Palm Cove in late 2017 which was intended to be the first
10 nm-based core and the proper successor to
Skylake. "
Rocket lake is supposed to use the third iteration, willow cove, backported to 14nm to get the best of both worlds, more IPC and more clocks.
Recent leaks suggest that the ageing Skylake architecture won't last beyond 2020's Comet Lake
