Regor processors supported the same technologies as Propus and Deneb counterparts, but there were a couple of significant differences between them. Propus and Deneb dies had 4 CPU cores and 512 KB L2 cache per core (Deneb also had 6 MB L3 cache), while Regor die had two CPU cores and 1 MB L2 cache, dedicated to each core.
