AMD’s Explosive DDR5 Patent Could Double Your RAM Speed – But Don’t Hold Your Breath
AMD has patented a “High-Bandwidth DIMM” for DDR5 that doubles per-pin data rates from 6.4 Gbps to 12.8 Gbps by adding buffer chips and splitting each module into two pseudo-channels. The design uses standard DDR5 chips and a register/clock driver to merge two normal-speed streams. The technology requires new motherboard and CPU support and remains a patent application.
