Hot Chips 2026: Intel’s Crescent Island

Hello you fine Internet folks,At Hot Chips, Intel talked a bit more about their upcoming Datacenter GPU codenamed Crescent Island.Crescent Island’s party piece is the ultra-high memory capacity curtesy of the LPDDR5X memory subsystem. Making Room for WhalesThat LPDDR5X subsystem can support up to 480 GB of DRAM which, at the time of writing, is the single highest capacity memory subsystem found on any “GPU”/AI accelerator.This means that a single Crescent Island can easily run Deepseek-V4 Flash straight out of the VRAM which is an achievement that no other non-HBM “GPU” can claim. However, the all-important memory bandwidth of Crescent Island is still unknown and when asked Intel’s response was “We are not disclosing that information at this time.”The front side only has 12 LPDDR modules on it with the remaining 8 modules on the backside.
