CPUReview is a hardware clue-free zone? (Score 1)

Unless I totally missed the point and 3/4 of the article is exposition and education, I'm not impressed w/ CPUReview's take on the tech.

There are a few interesting problems with the article but I think it's clear that the writer has no real clue about chip design or hardware in general. For instance, his estimation of the number of pins required to support address/data is off. Back in the bad old days of 8-bit 40-pin (and 16-bit 40-pin) devices, address and data lines were available on the same pins. The same can be done for i/o ports. The downside is that the speed of the HotRail chip would need to outstrip processor speed by 2. But the docs do mention up to a 1.6 ghz bus.
