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

(Image credit: Tom's Hardware) A couple of days ago, Intel, TeamGroup and ASRock came together to unveil the "HUDIMM" spec for DDR5 RAM. HUDIMM use a single 32-bit subchannel instead of populating a 64-bit wide bus with two 32-bit channels. This effectively cuts bandwidth and capacity in half but allows for cheaper DDR5 that uses less ICs per stick. Today, new testing done by HKEPC, with the help of Asus, confirms exactly that — HUDIMM will incur an almost 50% bandwidth penalty, reducing performance significantly. Go deeper with TH Premium: Memory This new testing is more substantiated and was done on an Asus ROG Maximum Z890 Extreme motherboard, using an Intel Core Ultra 9 285K. The outlet "matched the BIOS that supports HUDIMM modules" because, unlike a retail 1x 32-bit stick, the modified 2x 32-bit RAM's SPD will still tell the memory controller it's supposed to have a 64-bit wide bus. The PC will fail to initialize (POST) otherwise and be stuck with training errors.…
