Sunny Cove is a codename for a CPU microarchitecture developed by Intel, first released in September 2019. It succeeds the Palm Cove microarchitecture and is fabricated using Intel's 10 nm process node.[1] The microarchitecture is implemented in 10th-generation Intel Core processors for mobile (codenamed "Ice Lake") and third generation Xeon scalable server processors (codenamed "Ice Lake-SP"). 10th-generation Intel Core mobile processors were released in September 2019, while the Xeon server processors were released in April 6, 2021.[2]

There are no desktop products featuring Sunny Cove. However, a variant named Cypress Cove is used for the 11th-generation Intel Core desktop processors (codenamed "Rocket Lake"). Cypress Cove is a version of the Sunny Cove microarchitecture backported to Intel's 14 nm process node.[3]

The direct successor to the Sunny Cove microarchitecture is the Willow Cove microarchitecture, which powers the 11th-generation Intel Core mobile processors.[4]

Features[]

Sunny Cove was designed by Intel Israel's processor design team in Haifa, Israel.[5][6]

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, larger L2 cache (size product dependent), larger μOP cache, and larger 2nd level TLB. The core has also increased in width, by increasing execution ports from 8 to 10 and by doubling the L1 store bandwidth. Allocation width has also increased from 4 to 5. The 5-level paging scheme supports a Linear Address space up to 57 bits and a physical address space up to 52 bits, increasing the virtual memory space to 128 petabytes, up from 256 terabytes, and the addressable physical memory to 4 petabytes, up from 64 terabytes.[8][7]

Improvements[]

  • On average 18% increase in IPC in comparison to 2015 Skylake running at the same frequency and memory configuration[9][10]
  • Increase L1 data cache: 48 KiB (From to 32KB)
  • L2 cache: 512 KiB[11]
  • Larger (2.25k 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]
  • Add hardware acceleration for SHA operations (Secure Hash Algorithms)
  • New AVX-512 instruction subsets:
    • VPOPCNTDQ
    • VBMI2
    • BITALG
    • VPCLMULQDQ
    • GFNI
    • VAES
    • VNNI
  • 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 Skylake microarchitecture, and is manufactured using Intel's 14 nm process node. Cypress Cove is identical to Sunny Cove, aside from a number of improvements and other changes.[15] Notably the L1 data cache latency has been reduced from 5 cycles that is on Sunny Cove to just 3 cycles on Cypress Cove. Intel claims an increase of 19% in IPC in Cypress Cove-based Rocket Lake processors compared to Comet Lake.[15][16]

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.
