From what I understand it's great but has a lot of information that is outdated and downright counterproductive on today's hardware. I kinda wish people would take old gems like this and bring out an annotated version that adds updated information.
The particular details are long since irrelevant - even in 1996 optimizing for the 8086 was irrelevant. But the thought process, approach and lessons learnt from optimizing the 8086 are still relevant today.
In fact, they're probably more easily demonstrated through and example using the 8086 than in modern environments. I still use Abrash's S3 FIFO buffer story when I'm mentoring people.
So yes, but no.

The Penitum M is sort of like "the missing link" between old and newer architectures. From it "evolved" the Core Duo brand (I also have one of those around), Core 2 Duo, and Core i3/5/7 architectures. And while there are differences, the M is still similar enough to be representative.
