Ice Lake is Intel's codename for the 10th generation Intel Core processors based on the new Sunny Cove microarchitecture. Ice Lake is expected to replace the Coffee Lake, Whiskey Lake, Kaby Lake and Cannon Lake microarchitectures in 2019 and 2020, representing the architecture step in Intel's Process-Architecture-Optimization model.[2][1][3][4] Ice Lake will be produced on the second generation of Intel's 10 nm process, 10 nm+, becoming Intel's second microarchitecture to be manufactured on the 10 nm process following the limited launch of Cannon Lake in 2018.[2][5][6][7][8]

It is expected that Ice Lake will have in-silicon mitigations for the Meltdown and Spectre hardware vulnerabilities.[9]

Intel released details of Ice Lake during Intel Architecture Day in December of 2018, stating that the Sunny Cove core Ice Lake 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".[10]

The core Ice Lake will be built on, Sunny Cove, will feature 50% increase in the size of L1 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 paging table for main memory supports a Linear Address space up to 57 bits and a physical address space up to 52 bits, increasing the theoretical addressable memory space to over 4 PB, up from 64 TB.[10]

Ice Lake will feature Intel's Gen11 graphics, increasing the number of execution units (EUs) to 64, from 24 in Gen9.5 graphics, achieving over 1 TFLOPS of compute performance. Each EU supports 7 threads, meaning that the design has 512 concurrent pipelines. Feeding these EUs is a 3 MB L3 cache, a 4x increase from Gen9.5, alongside with the increased memory bandwidth enabled by LPDDR4X on low-power mobile platforms. Gen11 graphics also introduces tile-based rendering and Coarse Pixel Shadowing, Intel's implementation of multi-rate shading. The architecture will also include an all-new HEVC encoder design.[10]


  • 10 nm+ transistors
  • Gen11 GPU, include 64 EU and 512 ALU, brings 5K and 8K support[11]
  • L1 instruction/data cache: 32KB/48KB; L2 cache: 512 KB[11]
  • DisplayPort 1.4a & Display Stream Compression (DSC)
  • Native Thunderbolt 3 support[12]
