AMD Unveils Ryzen 9 9000HX and 9000HX3D "Zen 5" Mobile Processors for Enthusiast Notebooks
AMD today announced the Ryzen 9 9000HX and 9000HX3D line of mobile processors targeting enthusiast-segment gaming notebooks and portable workstations. These chips compete in the same market-segment as the Intel Core Ultra 200HX series. Codenamed "Fire Range," and powered by the "Zen 5" microarchitecture, the chip succeeds the "Zen 4" based "Dragon Range." This is essentially a thin BGA package of the desktop "Granite Ridge" chiplet-based processor, just the way "Dragon Range" relates to "Raphael." The chip has two "Zen 5" CCDs with full-sized "Zen 5" cores that are geared for high clock speeds, and have the full hardware FP implementation for AVX512, unlike the "Zen 5" cores on the "Strix Point" mobile processor.
AMD has, curiously, skipped single-CCD variants of "Fire Range," there are no Ryzen 7 9000HX models being announced today. There are just three processor-models—the Ryzen 9 9955HX3D, the Ryzen 9 9955HX, and the Ryzen 9 9850HX. The 9955HX3D is AMD's flagship mobile processor for gaming notebooks. It features a 16-core/32-thread configuration, and features 3D V-Cache memory on one of the two CCDs. The chip hence comes with 144 MB of "total cache" (L2 + L3). It ticks at 2.50 GHz base frequency, and can boost up to 5.40 GHz for the CCD with 3D V-Cache. It comes with a configurable TDP range of 55 W and 75 W. There is no NPU, but the client I/O die puts out a boatload of I/O that includes 28 PCIe Gen 5 lane, from which 24 are usable, so the discrete GPU has a PCI-Express 5.0 x16 connection, besides two M.2 NVMe Gen 5 connections directly from the processor.
