I thought it was a typo in the submission, but no, this is another article indeed on CXL x OpenCAPI. There was a great article on similar-but-different tech mashing up CXL and Gen-Z last week[1]! This article quickly acknowledges that last article right at the start, mercifully, letting me know I'm not crazy.
For reference, OpenCAPI here used a PCIe PHY (like CXL). Gen-Z PHY 1.0 could work over PCIe 4.0 or IEEE802.3bj (100Gbe, 25.78Gbps lanes), giving it far far broader physical reach.
It is fairly remarkable how limited CXL has been, at least until 3.0, which starts to grow many of these capabilities such as around shared memory, around switched fabric. That folk already had a start on one of these alternatives & have not wanted to give up all the amazing capabilities to get on the CXL bandwagon is unsurprising & cool to see. It's definitely one of the semi-rare genuinely-exciting fronts for computing hardware, that's not all just big huge players but is an open & exciting field.
