Intel is giving us a little more information and a first look at its next-gen Tiger Lake mobile processor this week at HotChips 32. The company already showed off its Tiger Lake processor last week with a very high-level preview of the lineup. of 11th generation mobility which you can check here.
Intel shows the death of the 11th Gen Tiger Lake processor and gives us a detailed look at everything new with its next generation mobility processors
Intel Tiger Lake processors are based on the 10nm ++ process node and feature the company’s latest Willow Cove cores. The main architecture of Willow Cove is based on the same foundations as the latest generation Sunny Cove architecture. It can be seen as a refinement of Sunny Cove in every way it can, but at the same time, the Willow Cove cores also feature a redesigned chip hierarchy for faster performance throughput.
The 10nm ++ process node is called by Intel the design of the 10nm SuperFin transistor. Intel itself claims that the SuperFin process provides the same performance boost as a proper node shrinkage. Intel said it achieved a performance increase of around 17-18% over the standard 10nm process node on 10th Gen Ice Lake chips while delivering much faster frequencies. You can read our full article detailing Intel SUPERFin transistor technology here.
Functional diagram of Intel 11th Gen Tiger Lake processor
Going to the newly unveiled details, Intel presented both a block diagram and a photo of its Tiger Lake processors. The block diagram mentions everything new about the Ice Lake chips and also the parts that have been kept.
First, let’s take a look at the similarities between Ice Lake and Tiger Lake processors. There are a few that include the DDR4 memory controller which supports speeds of 3200 MHz with capacities up to 64 GB. Other controllers such as SGX, Fuse, JTAG, SVID and OPIO are also similar to those used on Ice Lake chips. The USB Type-C display controller also includes DP 1.4 which was also featured last generation.
Tiger Lake processors only have a few blocks which remain similar to Ice Lake. The rest of the chip is brand new and it can be clearly seen in the diagram. Major new additions to Tiger Lake processors are Willow Cove cores, Xe LP graphics and media engine, 12MB L3 (latest level cache), a new display engine that supports 8K display (4 pipelines / 64 GB / s read bandwidth), IPU6 with 6 camera sensors (video up to 4K90, initially at 4K30) and additional support for LPDDR5 memory with speeds up to 5400 MHz (capacities of 32 Go). The rest of the blocks received major and minor upgrades over Ice Lake.

Intel Tiger Lake processors will use a dual ring interconnect. The Tiger Lake-U line of processors will feature up to 4 Willow Cove cores and an integrated Xe-LP GPU engine with 96 EU or 768 cores in total, operating at a frequency of approximately 1300 MHz. The Tiger Lake processors themselves are expected to achieve short burst frequencies of up to 5 GHz, which is impressive for its 10nm ++ process node.
The 11th Generation Tiger Lake Processor Family – Designed for Laptops and Gaming Laptops
Intel Tiger Lake processors will be called the 11th generation Core family and will remain exclusive to laptops and gaming notebooks. The line is reportedly available in three flavors, including Tiger Lake-Y, Tiger Lake-U and Tiger Lake-H. There have been several leaks for the Tiger Lake-Y and Tiger Lake-U processors which are being tested internally by various OEMs and laptop vendors who would integrate the processors into their next-gen devices.
the Tiger Lake-U The family would be made up of 15-28W TDP processors and would feature 4 cores and 8 threads, albeit at much higher clock speeds with an increase close to 4.50 GHz. These processors will also feature GT2 Tier, Gen 12 Xe GPUs, and will come in the UP3 package (BGA 1499). Tiger Lake-U will be the first to drop from the notebooks on September 2, as previously reported.
The manufacturer’s documents mention LPDDR5 support for the said family while the rest of the range will use either LPDDR4 (X) memory. We’ve seen laptops with LPDDR4 and LPDDR4X memory alongside Tiger Lake-U processors, so we can expect multiple configurations with a few high-end and more expensive variants offering LPDDR5 support.

Intel Tiger lake-y The family would be made up of 4.5-9W TDP processors and would have up to 4 cores and 8 threads. The GPU side would include a GT2 tier, a Gen 12 Xe GPU. Tiger Lake-Y processors will be delivered in the UP4 package (BGA 1598). The Tiger Lake-Y family reportedly supports LPDDR4X memory exclusively.
Then there is the high performance Tiger Lake-H range that would include up to 8 core chips and 16 threads based on the new Willow Cove architecture. The processors would carry up to 34MB of cache, or 24MB L3 (3MB L3 per core) and 10MB L2 (1.25MB per core). Tiger Lake processors will ship with a 48/32 KB asymmetric L1 cache and fully support the AVX2 and AVX-512 instructions. Tiger Lake-H processors will also feature dual-level (2LM) and SGX (Software Guard extensions) memory. Intel’s Tiger Lake-H family reportedly supports DDR4 speeds of up to 3200 MHz.

Intel also detailed that its Tiger Lake mobile processors can scale from 9W to 65W. We know that Intel is preparing Tiger Lake processors for at least three segments. These include Tiger Lake-Y, Tiger Lake-U, and Tiger Lake-H. Tiger Lake-U processors will initially hit market shelves in various OEM models next month, followed by Tiger Lake-Y later this year. The Tiger Lake-H range is scheduled for the first half of 2020 and is expected to feature TDPs ranging from 35W to 45 / W65W (cTDP up). All Tiger Lake processors will support PCIe Gen 4, USB 4, and Thunderbolt 4 functionality.
The 10nm Tiger Lake processors are said to take on the AMD-based 7nm Zen 2 Ryzen 4000 “ Renoir ” family when it officially launches on September 2.
