Strongly disagree. It is, at least in principle, possible to make an algorithm that an intel core i7 is the ideal chip for (that is, an intel core i7 IS the asic for this algorithm). You'd have to write the algorithm specifically for that task, but it is possible.
Wait, are we in the same thread?
Anyways, no you would have a chip-specific algorithm, this wouldn't magically make the i7 (a general computing device) suddenly become an ASIC.
This would possibly be a way to build social/economic ASIC-resistance into a coin, because it would be illegal to make it, and nearly impossible to compete with Intel on price.
Either way, I'm not exactly sure what you were reading when you wrote that. If you're not a native english speaker I apologize for possibly confusing grammar.
If ever single feature of the i7 were used, every FPU, every ALU, etc are all used in their most efficient way possible for the i7, then the only way you could beat it with a "mining ASIC" would be to just make more i7's. You could make one twice as powerful, but it'd require twice the silicon, twice the cost, twice the power, etc.
General use CPU's are so easy to beat for stuff like bitcoin, because the algorithm isn't optimized at the hardware level for those general CPU chips. If it is, then you can't really do much better.
Such an algorithm would be spectacularly hard to write, but I don't see why the possibility should be discredited.
I apologize if you're not a native english speaker and the technical aspects are hard to understand.
