I got a bit confused by the X3D CPUs as many places listed X3D is the equivalent to the largest i5. But on the flip side the latest X3D is a few years old so I didn't know why it's better than the more recent version of their non-X3D CPUs
The X3D chips have way larger caches so they punch well above their weight on many workloads that are traditionally cache bound. And with the 9000 series they figured out a better assembly method so they work even better than the 7000 or 5000 series ones.

The cpu naming is so bad and confusing, I think it’s deliberate to confuse consumers that aren’t up to date.
