The issue is your defect rate for larger chips. If a small laptop CPU only has 25% of chips being fully functional, a 4x the size server chip will only yield 0.

The issue is your defect rate for larger chips. If a small laptop CPU only has 25% of chips being fully functional, a 4x the size server chip will only yield 0.39% of chips being defect free. I say this having no idea what Intel's defect rate is right now, and I acknowledge fusing of bad sections can mitigate this a bit.
