AMD Sends Out Linux Graphics Driver Patches For "Arcturus" As New Vega Derived GPU
But indeed this "Arcturus" part isn't based on Navi but rather a new swing on Vega based on Vega 20 in part.
So what is Arcturus? Betting on a soon-to-be-announced workstation card we'd bet could be announced as soon as SIGGRAPH. Remember just days ago we spotted
a new AMD "GFX908" target added to the AMDGPU LLVM shader compiler code. GFX908 is a new Vega target not paired with an existing graphics card. It points to workstation due to ECC memory and other attributes.
We've also heard from AMD directly at the Navi event and E3 over their plans to continue to use Vega+HBM when it comes to workstation/compute offerings as Vega is still quite good in that regard.
So all things considered, Arcturus appears to be a forthcoming Vega workstation "Radeon Instinct" type offering we'd be could be announced at SIGGRAPH or Hot Chips based on the timing. Digging through this code drop today, it further points at a compute accelerator without any 3D support, "It's because Arcturus has not 3D engine."
