Qualcomm stacks LPDDR on CPU to slash HBM costs in data centers
Qualcomm unveils High Bandwidth Compute (HBC), stacking LPDDR memory directly atop CPUs to reduce reliance on expensive HBM. The approach aims to lower data center memory costs while maintaining high bandwidth. HBC targets AI workloads that demand fast memory access without the 'HBM tax.'
Meridian48 take
The real test is whether LPDDR stacking can match HBM's bandwidth and reliability in production, or if this is a niche play for latency-sensitive inference.
