|Sunny Cove µarch|
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 it was intended to be the first 10 nm-based core and the proper successor to Skylake. Prolong delays and problems with their 10 nm process and resulted in a number of improvised derivatives of Skylake including Kaby Lake, Coffee Lake, and Comet Lake. For all practical purposes, Palm Cove has been skipped and Intel has gone directly to Sunny Cove. Sunny Cove is expected to debut in mid-2019.
Sunny Cove is designed to take advantage of Intel's 10 nm process.
Key changes from Palm Cove

Sunny Cove introduced a number of new instructions:
CLWB- Force cache line write-back without flush
RDPID- Read Processor ID
- Additional AVX-512 extensions:
AVX512VPOPCNTDQ- AVX-512 Vector Population Count Doubleword and Quadword
AVX512VNNI- AVX-512 Vector Neural Network Instructions
AVX512GFNI- AVX-512 Galois Field New Instructions
AVX512VAES- AVX-512 Vector AES
AVX512VBMI2- AVX-512 Vector Bit Manipulation, Version 2
AVX512BITALG- AVX-512 Bit Algorithms

- Split Lock Detection - detection and cause an exception for split locks
- Fast Short REP MOV
Sunny Cove is Intel's core microarchitecture for a series of client and server chips that succeed Palm Cove (and effectively the Skylake series of derivative). Sunny cove introduces a very large set of enhancements and improvements of its predecessor including a wider and deeper pipeline. Sunny Cove is implemented in a number of chips including Lakefield, Ice Lake (Client), and Ice Lake (Server).
