DDR5 HUDIMM simulation with ASUS BIOS shows nearly 50% bandwidth loss - VideoCardz.com
50% bandwidth loss. That's the trade-off Intel and ASRock are betting will crash DDR5 prices—and reshape AI infrastructure procurement.

Why it matters
A cheaper DDR5 standard (HUDIMM) could lower memory costs significantly, but the 50% bandwidth penalty may force AI builders to recalculate their infrastructure strategies—especially if AMD support remains blocked.
