Meta fights soaring hardware costs by reusing old DDR4 server memory in new DDR5-only servers — custom CXL 2.0 chip marries legacy DDR4-2400 with cutting-edge D
CXL is a protocol that sits on top of the PCIe physical interface. As a result of this, many early CXL implementations were built by modifying existing PCIe IP, which is why such implementations inherited architectural c…
