Meta develops custom CXL 2.0 chip to reuse legacy DDR4 memory in DDR5-only servers amid rising hardware costs
By
Anton Shilov
Summary
Meta is developing a custom CXL 2.0 chip called Vistara that allows legacy DDR4-2400 memory to be used in new servers that only support DDR5-6400, as a cost-saving measure amid soaring DDR5 prices. The company recovers DDR4 memory from decommissioned servers and connects it to new AMD EPYC 'Turin' processor-based machines. South Korean startup Panmnesia has also developed a similar off-the-shelf CXL controller solution.
