AMD today solved the biggest challenge affecting its mobile processor family against Intel—CPU core-counts in the high-end HX-segment, with the introduction of the new Ryzen 7045HX series "Dragon Range" mobile processors. Based on the "Zen 4" microarchitecture, these processors offer core-counts of up to 16-core/32-thread, and target enthusiast gaming notebooks and mobile workstations. The processors debut the new "Dragon Range" multi-chip module (MCM). This is essentially a non-socketed version of the desktop "Raphael" MCM built in a mobile-friendly BGA package with a thin substrate and no IHS, with up to two 5 nm "Zen 4" 8-core CCDs, and a 6 nm cIOD (client I/O die).

The "Dragon Range" MCM uses the same chiplets as desktop "Raphael" Ryzen 7000 processors, and so its I/O is similar. The cIOD puts out a dual-channel (4 sub-channel) DDR5 memory interface, and a PCI-Express 5.0 x16 interface for discrete graphics, along with two PCI-Express 5.0 x4 links for up to two Gen 5 NVMe SSDs. The platform core-logic (chipset) is functionally similar to the desktop AMD B650E. All processor models in the series come with a TDP of 45 W, and a package power tracking (PPT) of "at least" 75 W. Each "Zen 4" CPU core comes with 1 MB of dedicated L2 cache, and each CCD has 32 MB of L3 cache.
