They also did 25M 4K IOPS on the same system. Anyway, it's basically an ad for Intel® Xeon® and Optane®.
That looks close to the maximum rate of an optane 5800x... 1.5 million 4k iops * 16 devices = 24 million 4k iops. It also looks close to the maximum of pcie4, 16 * 7.8GB / 4K = 32M > 25M.

Bingo.
No.Extending your reasoning, it would just be 1 40GB I/O per second. Each io request has a fixed cost, which is better measured with small requests. Bandwidth is not really relevant here.
