Intel's Xe3P GPU leaked: 160GB LPDDR5X bypasses HBM shortage

Leaked PCB shows 20 LPDDR5X modules, 640-bit interface, 760 GB/s bandwidth.

Deep Dive

Upcoming Intel Xe3P data center GPU features 20 8GB LPDDR5X modules for a total of 160GB, bypassing HBM shortages. Assuming a 32-bit interface, that's a 640-bit wide memory interface, or 10 channel memory interface if converted to 64-bit desktop equivalent. At 8800-9500 MT/s, memory bandwidth is 704-760 GB/s.

Key Points
  • 160GB LPDDR5X memory across 20x 8GB modules, bypassing HBM shortages.
  • 640-bit aggregate memory interface, equivalent to a 10-channel desktop system.
  • Bandwidth reaches 704-760 GB/s at 8800-9500 MT/s, competitive for AI inference.

Why It Matters

Intel's LPDDR5X design gives data center GPUs high capacity without HBM dependency, altering AI hardware competition.
