End of Intel-Pin-Compatible CPUs?

sonamchauhan writes ""Intel, Via bury the hatchet" proclaims this news.com article. The settlement reportedly allows Via to build Intel-pin-compatible CPUs for three years more, but Via must cease pin-compatibility after that." This settlement apparently closes out 27 existing lawsuits.

Woo!

Well, pin compatibility isn't the issue I'd be concerned with, but opcode compatibility.

Pin compatibility is not for end-users

[Rolman]

As someone who has been involved in development of computer boards (not just PCs), I can say pin compatibility is not aimed for the end-user's benefit, VIA C3 is not just intended to be a "replacement CPU". Although it could be used as such, it is not the biggest benefit of pin compatibility.

The main reason why it's desirable for Via to have a pin-compatible CPU with Intel's specification is because it shortens the development time and cost of a motherboard. It's easier and cheaper for the M/B manufacturer to design the board's layout if the signals are in the same place, because a re-layout of a M/B is very expensive in both time and money. (in some cases the full development can go upwards to several hundred thousand dollars)

Additionally, there are chipsets that can support both Intel and Via CPUs, (most notably some SIS SOC designs) making it even easier to make a M/B, but this fact it's not necessarily related to having interchangeable CPUs with a socket. Having a socket is of little to no use because Intel and Via CPU's are aimed at different market segments, anyway.

Remember the whole Slot-1/Slot-A fiasco? Intel developed the PII with a slot connector, and used patents/copyrights/trademarks/whatever to prevent AMD or any other CPU manufacturer to make pin-compatible CPUs. AMD then developed the Athlon to use exactly the same connector, although with different electrical specifications and pin definition. This move was aimed to facilitate the manufacturers' development and time-to-market efforts, never to give power to the end-user.

I can't believe nobody has mentioned this and everybody is easily misleaded into thinking this issue is not a important one. Maybe this shows just how few hardware development we have in the West.
