Features
Sunny Cove was designed by Intel Israel's processor design team in
Intel released details of Ice Lake and its microarchitecture, Sunny Cove, during Intel Architecture Day in December 2018, stating that the Sunny Cove cores would be focusing on single-thread performance, new instructions, and scalability improvements. Intel stated that the performance improvements would be achieved by making the core "deeper, wider, and smarter".[7]
Sunny Cove features a 50% increase in the size of L1 data cache, a larger L2 cache dependent on product size, larger μOP cache, and larger second-level
Improvements
- On average 18% increase in
- Increase L1 data cache: 48 kiB (from 32 kiB)
- L2 cache: 512 kiB[11]
- Larger micro-instruction cache (2304 entries, up from 1536)
- Larger re-order buffer (352, up from 224 entries)
- Dynamic Tuning 2.0 which allows the CPU to stay at turbo frequencies for longer[12][13]
- Hardware acceleration for SHA operations (Secure Hash Algorithms)
- New AVX-512 instruction subsets:
- Wider decoder (from skylake's 3 simple + 1 complex 4 way decoding to Sunny cove's 4 simple + 1 complex 5 wide decoder)
- 1.6x larger ROB (352, up from 224 entries)
- Scheduler
- 1.65x larger scheduler (160-entry, up from 97 entries)
- Larger dispatch (10-way, up from 8-way)
- 1.55x larger integer register file (280-entry, up from 180)
- 1.33x larger vector register file (224-entry, up from 168)
- Distributed scheduling queues (4 scheduling queues, up from 2)
- Scheduler
- Intel Deep Learning Boost, used for machine learning/artificial intelligence inference acceleration[14][13]

Cypress Cove is a CPU microarchitecture based on the Sunny Cove microarchitecture designed for 10 nm, backported to 14 nm. It succeeds the
Cypress Cove is implemented on 11th Gen Intel Core desktop processors (codenamed Rocket Lake). Rocket Lake and its underlying microarchitecture were first described in November 2020,[3] and was later released on March 30, 2021.[17][18]
SGX is removed from Rocket Lake.
Products
Sunny Cove powers the 10th generation of Intel Core mobile processors (codenamed Ice Lake) and the third generation of Xeon Scalable server processors (codenamed Ice Lake-SP). Cypress Cove is implemented on 11th-generation Intel Core desktop processors (codenamed Rocket Lake).
