Why not analyze the bits in detail? I already posted the complete CPUID

Then someone with detailed knowledge could compare the two?

As of this moment all of this is just an assumption - you might very
well be right, but it could also be something totally different. What if
the CPUID is nearly identical? This would lead to the conclusion that
the problem has completely different root causes.
