Measured timeline

📍 How it ended

The d‑Matrix Raptor chip demonstrated SRAM‑class bandwidth of about 100‑105 TB/s while consuming roughly one‑tenth the power of HBM, and its developers claimed a ten‑fold AI speed advantage over GPUs. SanDisk introduced the first 3D matrix memory chips that support the design, but the Raptor was still described as not yet a replacement for HBM.

The d-Matrix Raptor 3D-DRAM Accelerator is a new chip technology showcased at Hot Chips 2026. It boasts a data transfer rate of 100 TB/s, according to Tech Times. This speed is achieved through stacked DRAM, which also offers significant energy savings compared to High Bandwidth Memory (HBM).

The Raptor chip's performance is backed by real silicon tests, which achieved 105 TB/s, according to XenoSpectrum. This speed is coupled with an AI processing advantage, with claims of a 10x speed boost over traditional GPUs, as noted by StartupHub.ai. The chip's design, which fuses DRAM beneath the compute layer and eliminates the need for a PHY, contributes to its high bandwidth and low power consumption.

Despite these impressive figures, the Raptor chip is not positioned as a direct replacement for HBM. The technology's full potential and practical applications are yet to be fully explored.
