This is exactly what I wrote about. I have known about this for many years. And not from this article, but from my personal search experience.

It is also good to note that this will not only impact dictionary attacks without rules, but also ANY attacks against hash modes that use a host side hook for a portion of the computation. Several modes, such as 7z, do a portion of the computing on the GPU such as the KDF and then hand the data off to the CPU to do an AES/Compression step partway through the kernel. These modes will be severely impacted by bus speeds as well, regardless of your ability to amplify work on the GPU with rules or similar. There's more than one reason why sticking GPUs on x1 lane risers for hashcat is a bad idea and they may not be easy to spot if you aren't familiar with the underlying code.
