SPHBM4 Standard May Shift AI Chip Bottlenecks to Base Die Design
The new SPHBM4 standard for AI chips aims to bypass silicon interposers by connecting HBM directly to the organic package substrate. This change is designed to alleviate production bottlenecks in AI accelerator manufacturing rather than reducing per-chip costs.
Why it matters
Addressing packaging bottlenecks is critical for scaling the production of high-end AI hardware, which is currently limited by manufacturing capacity.
BlockBeats news, on June 23, analyst Damnang stated in an article posted on June 22 that JEDEC’s newly released SPHBM4 standard does not make DRAM faster, larger, or cheaper, but rather changes how HBM connects to the GPU. Traditional HBM4 requires connection to the GPU through a silicon interposer, while SPHBM4 aims to allow HBM to bypass the silicon interposer and connect directly to the organic package substrate.
