A leaker known as Haze on X claims that some partner-built versions of Intel's new GPU D-Series accelerator could carry as much as 512 GB of memory. The October 13 post, spotted by Video Cardz, names no board partners and offers no other specifications, so the claim should be treated with caution. Intel has not confirmed it.
Officially, Intel's own D-Series card, formerly known as "Crescent Island," ships with 160 GB of LPDDR5X, and the company allows partners to go as high as 480 GB. The 512 GB figure looks unusual when compared with the hardware. A leaked Crescent Island board from May showed 20 LPDDR5X sites, 12 on the front and eight on the back, each holding an 8 GB package for 160 GB total. Moving to 24 GB packages reaches 480 GB neatly, while 512 GB does not divide evenly across 20 sites.
The D-Series is an inference-focused accelerator built on Xe3P with 32 cores, 1.5 TB/s of memory bandwidth and up to 1.3 PFLOPS of FP8 compute. It is a 350 W, air-cooled PCIe 5.0 x16 card with no display or 3D graphics hardware, so gamers should not expect a consumer product. Earlier leaks already suggested Xe3P would skip Arc gaming cards.
Customer sampling is underway, but pricing and availability remain unknown. A 512 GB partner card, if it exists, would likely cost a great deal and would probably require a different board layout or a mix of package densities. There is no word on whether any partner is actually building one.
