Ice Lake is Intel's codename for the 10th generation Intel Core mobile and 3rd generation Xeon Scalable server processors based on the Sunny Cove microarchitecture. Ice Lake represents an Architecture step in Intel's process–architecture–optimization model.[1][2][3][4] Produced on the second generation of Intel's 10 nm process, 10 nm+, Ice Lake is Intel's second microarchitecture to be manufactured on the 10 nm process, following the limited launch of Cannon Lake in 2018.[1][5][6][7][8] However, Intel altered their naming scheme in 2020 for the 10 nm process. In this new naming scheme, Ice Lake's manufacturing process is called simply 10 nm, without any appended pluses.[9]

Ice Lake CPUs are sold together with the 14 nm Comet Lake CPUs as Intel's "10th Generation Core" product family.[10] There are no Ice Lake desktop or high-power mobile processors; Comet Lake fulfills this role. Sunny Cove-based Xeon Scalable CPUs (codenamed "Ice Lake-SP") officially launched on April 6, 2021.[11][12] Intel officially launched Xeon W-3300 series workstation processors on July 29, 2021.[13]

Ice Lake's direct successor in mobile is Tiger Lake, a third-generation 10 nm SuperFin processor family using the new Willow Cove microarchitecture and integrated graphics based on the new Intel Xe microarchitecture.[14] Ice Lake-SP was succeeded by Sapphire Rapids, powered by Golden Cove cores.[15] Several mobile Ice Lake CPUs were discontinued on July 7, 2021.[16]

Design history and features

[edit]

Ice Lake was designed by Intel Israel's processor design team in Haifa, Israel.[17][18]

Ice Lake is built on the Sunny Cove microarchitecture.[19][20] Intel released details of Ice Lake during Intel Architecture Day in December 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".[20]

Ice Lake features Intel's Gen11 graphics, increasing the number of execution units to 64, from 24 or 48 in Gen9.5 graphics, achieving over 1 TFLOPS of compute performance.[citation needed] Each execution unit supports 7 threads, meaning that the design has 512 concurrent pipelines. Feeding these execution units is a 3 megabyte L3 cache, a four-fold increase from Gen9.5, alongside the increased memory bandwidth enabled by LPDDR4X on low-power mobile platforms.Gen11 graphics introduces tile-based rendering. It also features Coarse Pixel Shading (CPS), which is Intel's implementation of variable-rate shading (VRS). The architecture also includes an all-new HEVC encoder design.[20] On August 1, 2019, Intel released the specifications of Ice Lake -U and -Y CPUs.[21] The Y-series CPUs lost their -Y suffix and m3 naming. Instead, Intel uses a trailing number before the GPU type to indicate their package power; "0" corresponds to 9 W, "5" to 15 W, and "8" to 28 W. Furthermore, the first two numbers in the model number correspond to the generation of the chip, while the third number dictates the family the CPU belongs to (i3, i5, etc.); thus, a 1035G7 would be a 10th generation Core i5 with a package power of 15 watts and a G7 GPU.

Pre-orders for laptops featuring Ice Lake CPUs started in August 2019, followed by shipments in September.[22]

Development History

Announcement and Design Goals

Intel first publicly detailed its Ice Lake microprocessor family during a keynote at Computex 2019 in , , positioning it as the company's inaugural 10nm-based client processor platform for . The codename "Ice Lake" follows Intel's longstanding convention of drawing from North American geographic features, particularly lakes, to evoke themes of power and fluidity in . As a successor to the 14nm and architectures, Ice Lake addressed longstanding delays in Intel's 10nm roadmap, which had originally projected high-volume manufacturing by the end of 2017 but faced repeated setbacks due to yield challenges and process refinements. The shift to 10nm aimed to deliver density improvements of approximately 2.7x over the 14nm node, enabling greater integration and power efficiency for thin-and-light laptops. Key engineering targets included an average 18% uplift in instructions per clock (IPC) through the new Sunny Cove core , compared to the Skylake baseline, to enhance single-threaded performance in productivity and creative workloads. Ice Lake's design emphasized mobile efficiency, integrating Gen11 graphics capable of up to 2x the performance of prior-generation integrated solutions in gaming and content creation scenarios, such as Total War: Three Kingdoms. Additional goals focused on AI acceleration via DL Boost, delivering up to 2.5x faster inference throughput compared to the previous generation in benchmarks like AIXPRT, and native support for Thunderbolt 3 to streamline high-speed connectivity in form factors. These features targeted the premium thin-laptop segment, aiming to sustain Intel's leadership amid rising competition in power-efficient mobile processors.

Release Timeline

Intel's Ice Lake mobile processors, part of the 10th Generation Core family, were officially launched on August 1, 2019, marking the company's first 10nm client products, with the Core i7-1065G7 serving as the inaugural SKU. These processors were showcased at in early September 2019, and the first laptops featuring them, including the Dell XPS 13 2-in-1, became available starting that month. By the 2019 holiday season, Ice Lake had been integrated into over 30 laptop designs from various OEMs, enabling widespread adoption in ultrathin and 2-in-1 devices. For server variants, began sampling Ice Lake-SP processors, the third-generation Scalable family, to select partners in June 2019. The general availability of these processors was delayed from initial projections and occurred on April 6, 2021, with the 40-core Platinum 8380 as the flagship model offering 60 MB of cache and support for eight-channel DDR4 memory. The postponement was influenced by production challenges, including disruptions from the that affected supply chains and qualification timelines.

Architecture and Features

CPU Microarchitecture

The Sunny Cove microarchitecture powers the Ice Lake family of processors and marks Intel's first major CPU core redesign since Skylake, enabling a transition to the 10 nm process node for increased transistor density and efficiency. This shrink from the previous 14 nm node allows for more complex structures within the same die area, supporting advanced features while maintaining compatibility with the x86-64 instruction set. Sunny Cove emphasizes deeper out-of-order execution, wider pipelines, and smarter resource allocation to boost single-threaded performance, with configurations scaling from dual-core mobile designs to multi-core server setups. A core highlight is the pipeline enhancements, including a 5-wide decode stage that can process up to five instructions per cycle, paired with a 4-wide execution engine capable of dispatching instructions to a broader array of functional units, such as additional integer and floating-point ALUs and FP multipliers. These changes contribute to an average 18% increase in instructions per cycle (IPC) compared to Skylake cores, as measured across a range of workloads at iso-frequency. Branch prediction is improved via a larger branch target buffer (BTB) expanded to approximately 5,000 entries from Skylake's 4,000, reducing misprediction penalties and enhancing front-end efficiency.
