Recently Intel released Alder Lake-based processor, the Core i9 12900K, and the platform is poised for the future with its incredibly fast performance paired with DDR5 memory, however works with DDR4 as well, really well actually.

It has 2x channels per dimm

"With DDR5, each DIMM will have two channels. Each of these channels will be 40-bits wide: 32 data bits with eight ECC bits. While the data width is the same (64-bits total) having two smaller independent channels improves memory access efficiency."

Arent those just memory ranks? You can use quad rank kit with ddr4 with two ranks per channel.

You are right but there is another improvement that could be responsible.

Check the images under "DDR4 vs DDR5 memory topologies" -text is part of the image so you cant search for it.
The last image shows both IMC controllers connect to both ram channels at the same time.

Thanks Hilbert for the interesting review !

I'd leave a comment on a typo here : on page 3 "Hardware & Software Used", the link to the RTX 3090 review points to the RTX 2080 Ti

Looks like in the future there's great potential for more performance. Just like when we saw the first DDR4 reviews.
