Intel Alder Lake-S supports dual-channel DDR5 memory
The upcoming 12th Gen Core desktop series codenamed Alder Lake-S was rumored to support DDR5 memory, but it was never really confirmed. The new data that was sent to us appears to confirm this fact:
Updated RKL-S DDR4 2DPC SBS configuration
Added ADL-S DDR5 UDIMM 1DPC B2B ECC and Non-ECC configuration
Added ADL-S DDR5 UDIMM 2DPC B2B ECC and Non-ECC configuration
Updated TGL-H DDR4 T3/12L WP ECC 1DPC configuration
Added TGL-H DDR4 MD 1Rx16 configuration

Anonymous tip.
Neither AMD nor INTEL have officially confirmed DDR5 support for their upcoming architectures. It is worth noting that both companies will shift to new platforms at the same time. AMD will adopt a new AM5 socket to support Zen4 architecture, while Intel will introduce LGA1700 socket for its (alleged) 600 motherboard series.
The data also points towards DDR3 and DDR4 support on Tiger Lake-H. The series is expected to be a successor to Comet Lake-H, Intels high-end flagship mobile series for gaming laptops.
