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

HUDIMM is being proposed as a cheaper memory spec using only 1x 32-bit subchannel per stick instead of 2x 32-bit in order to populate less ICs. Turns out, halving the bandwidth like that actually slashes the performance in half too, alongside the expected capacity reduction. Two HUDIMMs running i...
