Qualcomm unveils \'High Bandwidth Compute\' as HBM alternative, enters AI chip race

Qualcomm is stepping up its return to the data centre AI chip market with a new memory architecture using LPDDR instead of high-bandwidth memory (HBM). It unveiled High Bandwidth Compute and plans to launch its AI250 inference accelerator in mid-2027. Qualcomm says the near-memory design can deliver up to 133TB/s bandwidth and improve bandwidth per watt versus HBM, though some note the comparisons are not like-for-like. It is also strengthening ties with Meta and Microsoft.
