No two chips are the same; this is true even if both [[dies]] came from the very same [[wafer]]. Likewise, when stretching a processor to its limits, even the individual cores on a single [[monolithic integrated circuit]] produce slightly different performance characteristics. Testing individual cores by disabling all the other [[cores]] will reveal which ones happen to have better thermal and voltage properties and are stable at higher frequencies. They will each slightly differ.

[[Intel]] attempts to exploit those "superior cores" with Turbo Boost Max Technology. During the manufacturing process, Intel is able to test each die and determine which cores possess the best overclocking capabilities. That information is then stored in the CPU in order from best to worst.

=== Cascade Lake improvements ===

With the introduction of {{intel|Cascade Lake X|l=core}}, Intel improved the way TBMT works by operating on four cores instead of two. The four cores are split into two groups of two cores. The first group operates at the full TBMT frequency in a similar mannar to the prior generation. The second group can boost to 100 MHz less than the first group. For example, the [[Core i9-10980XE]] has a TBMT 3.0 frequency of 4.8 GHz meaning the two best cores could boost to 4.8 GHz with two 2nd best cores capable of boosting to 4.7 GHz as well.
