AMD Ryzen 7000 “Phoenix Point” Mobile CPUs Lack PCIe Gen 5 and up to 256GB of Dual Channel LPDDR5-7600 Memory

AMD announced its Ryzen 7000 mobile processors at CES 2023. Ignoring the Zen 2/Zen 3 refreshes, the next-gen lineup will consist of two product stacks: Phoenix Point and Dragon Range. The former will power most high-performance notebooks, with Dragon Range reserved for the fastest gaming laptops. Phoenix Point will be a monolithic die with 20 PCIe Gen 4 lanes, permitting a Gen 4 dGPU x16 slot and an x4 slot for M.2 drives. PCIe Gen 5 support isn’t included on these 45W SoCs.

Phoenix Point will be fabbed on TSMC’s 4nm EUV process. The CPU side will consist of a single 8-core CCD with 32MB of L3 cache. (Provigil) The memory controllers are even more powerful than the desktop Zen 4 platform. Phoenix supports up to 256GB of DDR5-5600 or LPDDR5-7600 memory, twice as much as Raphael. Additionally, unlike AM5, all 20 PCIe Gen 4 lanes will be available for use rather than being connected to the chipset.

Coming to the mobile graphics processor, we’re getting another big upgrade in the form of the Radeon 8x0M lineup. The Radeon 780M will succeed the 680M. The CU and ALU counts are the same, but the architecture has been updated to RDNA 3 with a boost clock of up to 2.9GHz. Remember that, like the desktop RDNA 3 parts, the core and backend clocks are decoupled. Furthermore, every Compute Unit will include a faster ray-accelerator unit and a dedicated AI unit (repurposed vector unit).
