🚨META FINDS A WAY TO REUSE OLD MEMORY FOR AI SERVERS Meta has built a custom chip called Vistara that lets older DDR4 memory work inside newer DDR5 servers. Slower DDR4 handles less urgent data, while faster DDR5 is saved for high-performance AI workloads. Meta says the setup cuts costs, reduces e-waste, and helps stretch hardware supply during the global memory shortage.(Coin Bureau)
