Intel Xe (stylized as Xe, unofficially "Gen 12"[1]) is General Purpose GPU (GPGPU) and discrete GPU (gGPU) product under development by Intel, reportedly codenamed Artic Sound.

Intel Xe includes a new instruction set architecture – the technology is expected to become available with Intel's Tiger Lake products.

History[edit]

In April 2018, it was reported that Intel was assembling a team to develop discrete Graphics Processing Units, targeting both data-centers, as well as the PC gaming market, and therefore competitive with products from both Nvidia and AMD.[2] Rumors supporting the claim included that the company had vacancies for over 100 graphics related jobs, and had taken on former Radeon Technologies Group (AMD) leader Raja Koduri in late 2017 – the new product was reported to be codenamed "Artic Sound".[2] The project was reported to have initially been targeting video streaming chips for data centers, but had its scope expanded to include desktop GPUs.[2]

In June 2018, Intel confirmed it planned to launch a discrete GPU in 2020.[3]

In September 2019, hothardware.com reported that the Xe graphics (formally as "Gen 12") would represent a large change in the Instruction Set Architecture (ISA) of Intel's GPUs, with practically all instruction encodings being altered.[4] The Xe graphics ISA is expected to ship with the Tiger Lake product line.[4]

The first functional discrete "Xe" GPU, codenamed "DG1", was reported as having begun testing in October 2019.[5]

According to a report by hexus.net in late 2019, a discrete GPU would launch in mid 2020; combined GPU/CPU (GPGPU) products were also expected, for data center and autonomous driving applications. The product is expected to be initially built on a 10 nm node (with 7 nm products in 2021) and use Intel's Foveros die stacking packaging technology (see 3D die stacking).[6]

Intel officially announced their Xe general HPC/AI GPU codenamed Ponte Vecchio on November 17, 2019. The chip is to use Intel's 'Embedded Multi-Die Interconnect Bridge' (EMIB) and Foveros die stacking packaging on a 7nm node. The new GPU is expected to be used in Argonne National Laboratory's new exascale supercomputer, Aurora, with compute nodes comprising two Intel Xeon (Sapphire Rapids) CPUs, and six Ponte Vecchio GPUs.[7][8]
