New cost-effective DDR5 memory 'HUDIMMs' show around 50% reduction in throughput with single subchannel — Two HUDIMMs are as fast as a single stick of regular DDR5 RAM

What happened

HKEPC testing confirms HUDIMM reduces DDR5 bandwidth by approximately 50% using a single 32-bit subchannel. This new cost-effective spec, unveiled by Intel, TeamGroup, and ASRock, halves capacity and throughput compared to standard DDR5. The trade-off offers lower manufacturing costs but significantly lower performance.
