No, that would cost more. The distinction between Xeon/i9/i7/i5
is simply how well they test after manufacture.
Xeons were premium because there had to be less manufacturing errors to end
up with larger caches.
But your i9 there has a larger cache, so maybe that quality dimension has
This is interesting reading...
I guess the heat
