Summary of announcement at online event 'Architecture Day 2020' such as Intel's next-generation mobile processor 'Tiger Lake' and Xe graphics
Intel held an online event 'Architecture Day 2020' on August 11, 2020 (Tuesday). Among them, we announced information on the next-generation SoC ' Tiger Lake ' and our original GPU architecture ' Xe '.
Architecture Day 2020 | Intel Newsroom
◆Next Generation SoC with 11th Generation Core “Tiger Lake”
Intel's next-generation mobile processor 'Tiger Lake' has four 11th-generation Core ' Willow Cove ' cores, and the GPU has 96 Xe-LP graphics execution units. In addition to supporting LPDDR5 memory, it also supports PCIe 4.0 and GNA 2.0. In addition, L2 cache was increased from 1.25MB in the previous generation Sunny Cove to 512MB, and L3 cache was also increased to 24MB.
Furthermore, the point that Tiger Lake has adopted a new manufacturing process called ' Intel 10nm SuperFin ', whereas the previous generation Ice Lake was manufactured by Intel 10nm process. This Intel 10nm Super Fin is positioned as an improved version of the conventional 10nm process.
Intel appeals that it has improved
◆Intel 12th Generation 'Xe' Graphic Architecture
First seen at Tiger Lake, the Xe-LP graphics are Intel's 12th generation graphics architecture, designed for improved performance and reduced power consumption. Intel also appealed to AAA titles such as
Also, this Xe-LP is not only used as one part of the SoC, but also adopted by the discrete GPU 'DG1' that Intel announced in 2018 that it will 'release in 2020' and the GPU 'SG1' for servers. I heard that. DG1 which adopted Intel 10nm SuperFin in the manufacturing process will be sold for O and EM, and Intel has announced that it has already started production.
Xe-HP for the data center, Xe-HPC for the general public, and Xe-HPG for gaming were also announced. Detailed specifications have not been announced, but it is said that the Xe-HPG will be produced by a third-party foundry and will appear in 2021. Intel's release of discrete GPUs for gaming means competing with NVIDIA, which develops the GeForce brand, and AMD, which develops the Radeon brand, as rivals.
◆4 layer
Intel sells Optane persistent memory and Optane™ DC SSD that are based on the memory technology “ Optane Technology ” announced in 2019. Barlow Pass and Alder Stream using the second generation of Optane memory using this Optane technology are scheduled to be launched in 2020.
In the second-generation Optane memory, the memory cell array, which had a two-layer structure, is changed to a four-layer structure, achieving double the recording density of the conventional type. When combined with an SSD controller that supports PCIe 4.0, it is possible to expect more than twice the read/write speed of the Optane SSD released at the time of article creation. It also seems to improve the latency of random read speed.
3D Xpoint used for non-volatile memory is a technology developed by Intel and Micron Technology of semiconductor manufacturing. Since 3D XPoint will also be used for the 2nd Generation Optane SSD, manufacturing is probably expected by Micron Technology.
◆2021 roadmap
Intel announced that the next generation of Willow Cove will be the Golden Cove core with a 10nm process in 2021. As a result, it can be expected to further improve performance, optimize AI and 5G communication, and improve security. Desktop processor ``Alder Lake'' adopting Hybrid x86 architecture scheduled to appear in 2021 seems to be configured like ARM's
