I guess if they fix the problem via softare rather than ficing the hardware, who cares except perhaps the software developers? The end result is much the same.

The reason I am amazed is that I did not think the CPU was so complex that it wass possible for so many unusual states and conditions to arise. I had assumed that the complexity was hidden within tried and tested building blocks strung together. Having used TLBs within most modern cpu's for some time, I assumed the TLB was a well established design simply bolted on from a previous generation.

You must remeber I said "I" was amazed. There is a difference between the phrase "i am amazed" and the phrase "it is amazing". This speaks more about my limited knowledge than about the state of Intels engineers. It was just a personal observation.

You are right that I am very cynical.

Lol at the free gasket. Although this is not really a fair analogy - here you are talking about a fault that developers thru wear. The design fault that allowed the excessive wear would parheps be much harder to track down since it only shows itself after a long period of use. The design faults in cpu's can be detected at any time - they do not develop over time thru wear. But I take your point.

Still it would be much more likely for a manufacturer to address hardware bugs if the chip were ot be manufactured for, say 10 years rather than 10 months. After all manufactureres such as Intel do apply fixes to their hardware over time (steppings). The longer the chip lasts, surely the more fixes will be made.
