Process Technology
- See also: Cannon Lake § Process Technology
Ice Lake is fabricated on Intel's second-generation enhanced 10 nm process called "10 nm+". Versus the first generation 10nm which was used for Cannon Lake, 10nm+ features higher performance through higher drive current for the same power envelope. Intel says that Ice Lake is built on their learnings from their Cannon Lake products which were largely treated as a learning vehicle. Between Cannon Lake and Ice Lake, a number of changes were made in order to improve the process for their products. One such change was the addition of an extra metal layer (originally said to be 12, is now presumably 13 on Ice Lake) in order to improve the power delivery of the chip. Additionally, they have improved the threshold voltage of the transistors as well as their MIM cap among other changes.
Compiler support
Support for Ice Lake was added in LLVM Clang 6.0 and GCC 8.0.

Overview
The Ice Lake system on a chip is a 10-nanometer SoC that is aimed at the mainstream to premium mobile and the thin-and-light market. The microprocessor consists of five major components: CPU cores, LLC, ring interconnect, system agent, and Gen11 graphics. While a lot of what Ice Lake provides is inherited from the prior generations, Intel claims that every IP on Ice Lake has been enhanced in one way or another. A major enhancement in Ice Lake over the prior generation is the integration of up to four Sunny Cove cores which provide a significant uplift in IPC. Those cores also bring AVX-512 support for the client market. Those cores, along with the system agent and the GPU, are linked over Intel's ring interconnect. The chip is fed through a new integrated memory controller that supports quad-channel 32-bit LPDDR4X memory, providing bandwidths in the range of 50-60 GB/s. Ice Lake has a new integrated GPU which is based on their Gen11 microarchitecture which provides a large improvement in graphics performance.
The system architecture in Ice Lake has been redesigned. Intel added a new Gaussian Neural Accelerator (GNA) for the acceleration of inference applications. There is a new 4th-generation image processing unit (IPU). There is a new Thunderbolt 3 integration. Ice Lake has four Thunderbolt 3 ports. All four ports have the same capabilities and can be used simultaneously at full performance at up to 40 Gbps per port. Intel also upgraded the display engine to Gen11 with an improved display pipe that has a new Adaptive Sync and HDR-capable display pipes that support HDR 3 and DisplayPort 1.4, supporting error correction and compression.
Ice Lake chips integrate the PCH die on-package communicating over the on-package interconnect (OPI). The new PCH The PCH has an expanded I/O support for PCIe, USB, SATA, as well as audio DSP for load power voice processing. It also integrates WiFi 6+ CNVi.
On the platform level, there is a new integrated power delivery (FIVR) on both the PCH and the CPU which Intel says allows them to save on platform area by about 15% and it reduces the power delivery rails for the OEMs by roughly half.

Integration
GNA
Ice Lake introduced a new low-power neural processor called the Gaussian Neural Accelerator v1.0 (GNA) which is integrated on the SoC and runs at very low power even when the GPU and CPUs are turned off. The GNA can be used for long-running tasks (e.g., real-time meeting transcription). The GNA can operate while the remaining parts of the SoC are in idle in order to have minimal impact on performance.
IPU
Ice Lake incorporates 4th generation image processing unit (IPU). The IPU was first introduced with Skylake mobile SoCs (note that those were 3rd gen). The 4th Gen IPU found in Ice Lake introduces a number of new enhancements. It introduces new support for 4K video capture at 30fps. There is also new hardware support for better de-noising which supports up to 16 megapixels stills in low light conditions. In addition for support more camera simultaneously, the IPU incorporates a new concurrent image pipeline, supporting multiple different processing from the same camera stream, allowing a single camera to take the functionality of multiple sensors. A common example of that is devices with both IR and RGB cameras in the laptop bezel which can now be changed to a single camera. Intel says they are exposing more registers from the IPU to software in order to provide more flexibility for applications that make use of that for machine learning. It’s also worth noting that Intel integrated the MIPI interface onto the processor as well. Previously that was found on the chipset. The change significantly improves the latency, a required attribute needed for more advanced ML-specific applications. Some of those changes are designed to form the foundation for future generations of improvements.
Thunderbolt IO subsystem
By far the largest new integration in Ice Lake is the Thunderbolt I/O Subsystem. According to Intel, this is the largest integration they have done since the integration of the graphics processing unit in Sandy Bridge. When Ice Lake was introduced, Thunderbolt 3 was the fastest and most versatile connector that was available. Not only is it four times faster than USB 3.1, but it also supports additional peripherals over PCIe, USB 3, and DisplayPort.
Previously (e.g., with Whiskey Lake), for OEMs to support Thunderbolt 3 in mobile devices, they had to use Intel's Titan Ridge controller. Titan Ridge was a discrete Thunderbolt 3 chip that came with either one or two dedicated Thunderbolt 3 ports. In order to support everything that was necessary (e.g., legacy USB 2 as well as high speed PCIe Gen 3), the controller was connected to both the CPU and the hipset. The chipset was connected over four PCIe Gen 3 lanes. The CPU had two DisplayPort connections. Each of those passed over four PCIe Gen 3 lanes. In order to offer legacy I/O support, a direct USB 2.0 link from the PCH went to the port. For charging capabilities, the port was also connected directly to a Power Deliver (PD) controller. In total, 17 PCIe Gen 3 lanes operating at around 8 GT/s were required between the Titan Ridge controller and the chipset and CPU.
Due to the design complexity introduced by the discrete controller, most mobile devices that made use of Titan Ridge only supported it on one side of the device - typically on the side of the device closer to the controller itself.
With Ice Lake, Intel simplified the overall design considerably. The biggest change comes from the fact that most of the Titan Ridge logic has been integrated into the Ice Lake SoC itself, reducing board space, routing, and the overall bill of materials. Instead of the seventeen PCIe lanes that were required by the Titan Ridge controller, Ice Lake exposes just eight lanes – four lanes to each retimer which drive the signals to the connectors. Therefore, in total there are just eight lanes operating at 20 GT/s instead of seventeen lanes operating at 8 GT/s. The reduction of lanes, along with their associated components such as the buffers, reduces the overall power consumption of the system. Intel stated that, depending on the exact device design, they saw a reduction of up to 300 mW per port when the port was fully utilized. Previously, the dual-port Titan Ridge controller had a TDP of up to 2.4 W, so the overall saving is fairly sizable. The additional power saving thus translates to better performance as more of the overall power budget can be allocated for the GPU and CPU instead of the I/O.
One of the other benefits of the Thunderbolt 3 integration is that half of the lanes can be exposed to each side of the device. With the Titan Ridge controller, offering Type-C ports on the side further from the controller was more complex and was quite rare and most OEMs simply opted to offer a legacy connector of some sort such as a USB 2.0 on that side. With Ice Lake, the direct Thunderbolt lanes that go to each retimer are easily exposed to both sides of the device, meaning, at least in theory, OEMs should have no problem offering symmetrical connections on both sides of the device.
Like Titan Ridge, each retimer supports two ports. The retimers themselves are still only sold by Intel but they are a fraction of size, so there is also a modest board space saving advantage as well. Therefore, actually, the diagram above is almost identical when offering support for up to four Thunderbolt 3 ports, twice as many as most Titan Ridge-based designs. For full support, those additional ports just need a new dedicated USB 2 connection to the PCH, and in order to also offer charging capabilities through that port, you also need a PD controller. Premium-design laptop should, therefore, be able to have up to four Thunderbolt ports – each supporting everything from power delivery to the legacy I/O to the latest high-speed interfaces such as DisplayPort and USB 3.1.
Clock domains
Ice Lake is divided into a number of clock domains, each controlling the clock frequency of their respective unit in the processor. All clock domains are some multiple of the [virtual] bus clock (BCLK).
- BCLK - Bus/Base Clock - The system bus interface frequency (once upon a time referred to the actual FSB speed, it now serves as only a base clock reference for all other clock domains). The base clock is 100 MHz.
- Core Clock - The frequency at which the core and the L1/L2 caches operate at. (Frequency depends on the model and is represented as a multiple of BCLK).
- Ring Clock - The frequency at which the ring interconnect and LLC operate at. Data from/to the individual cores are read/written into the L3 at a rate of 32B/cycle operating at Ring Clock frequency.
- IGP Clock - The frequency at which the integrated graphics (Gen11 GPU) operates at. Data from/to the GPU are read/written into the LLC at a rate of 64B/cycle operating at this frequency as well.
- IPU - The frequency at which the image processing unit operates at
- MemClk - Memory Clock - The frequency at which the system DRAM operates at. DRAM data is transferred at a rate of 8B/cycle operating at MemClk frequency.
