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. 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.
Design history and features
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".
The core Ice Lake is built on, Sunny Cove, features 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 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.
Ice Lake features 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 Shading (CPS), Intel's implementation of variable-rate shading (VRS). The architecture also includes an all-new HEVC encoder design.
