It's been a while since we heard the codename Arcturus but now it pops up again. This GPU architecture is believed to be the successor to Navi and WCCF Tech writes we may see the first datacenter implementations sometime in 2020.
Yesterday, HWiNFO added preliminary support for AMD Arcturus in its latest v6.13-3945 BETA release. In addition to that, Komachi_Ensaka revealed a series of chips that are marked under AMD's AI family and Arcturus seems to be one of them. The AI family also includes other GPUs such as Vega 10, Vega 12 and Vega 20. Judging by the AI name, the list might be mentioning the AMD Radeon Instinct based GPU accelerators as all three Vega GPUs listed have been featured inside a Radeon Instinct graphics cards for HPC and Artificial Intelligence. Arcturus also falls in the same list but looking at how the chips are mentioned in top-down order, the ones at the bottom for each family are also the latest additions to each specific lineup.
