In Case You Were Wondering How CPUs Are Made (i3, i5 and i7 are just defective i9’s)

      So basically all CPUs have the same power. It’s just that some are more damaged then the other and the i’s are just damage scales.

    2. It’s been like that since the beginning of wafers. Or resistors. Or capacitors. Or pretty much anything. Manufacturing electronics in general isn’t an exact science.

      The process of organizing the differences is called “binning” or that’s what it used to be called.

    3. The mind-blowing thing is how do they put billions of transistors on that small area. I’ve tried to understand but my basics are not strong. It feels like magic, humans are amazing!

      What’s the computing power of a perfect i9 disc? Assuming I’m an idiot with zero understanding how vague that question is.

    5. Not sure how common this still is, but back in the day AMD used to sometimes disable functioning cores just to meet demands for lower product lines. Consequently, these deactivated cores could be reactivated and, with a reasonable likelihood, you could effectively have a high end CPU for the cost of a low end part. It wasn’t guaranteed, but in some product runs the likelihood of getting a good disabled core was possibly more likely than actually getting a defective core.

      Weird how this is basically just like manuka honeys rating of authenticity. The higher grade just accounts for less of that fake honey.

    7. This isn’t always true: some lower end product lines were designed with its own distinct topography, such that it didn’t have disabled cores, it just doesn’t have as many in total in the first place…but of course *that* could have some defective cores, and then those would be sold as an “even lower end” part.
