Intel "Crescent Island" GPU Gets D-Series Name, Supports Up to 480 GB of LPDDR5X

The newly named D-Series GPU has up to 480GB of LPDDR5X memory, 1.5TB/s of memory bandwidth

Intel rates it for up to 1.3 PetaFLOPS of FP8 performance, with support for formats ranging from FP4 to FP64. It features a total of 32 Xe3P cores, 256 XMX engines, 32 MB of unified L2 cache.

No cost estimates currently, I hope they launch a generic blower style variant at a later date for prosumer workstations.
