AMD’s next-gen Ryzen 7000 mobile processors codenamed “Phoenix” may feature 3D stacked V-Cache to boost gaming performance despite leveraging integrated RDNA 2 graphics. In an industry first, this will be the first onboard GPU to come with 3D stacked L3 cache, something only the Ryzen 7 5800X3D has managed to date. And that’s a desktop processor without integrated graphics to boot.
AMD plans to launch three Zen 4 processor stacks in the next 12 months, namely Raphael, Dragon Range, and Pheonix. These will be for the desktop, high-performance mobility, and ultrabook markets, respectively. Raphael and Dragon Range will likely be based on the same chiplet die architecture with 16 cores and 32 threads and a base TDP of 55-65W. Phoenix will be 15-28W APU with a monolithic 8-core die.
AMD is reportedly looking to make up for the relatively low core count and TDP with a fat L3 cache. It’s unclear whether the V-Cache is for the CPU or the GPU, or both, but I’m willing to bet it’ll be exclusive to the graphics processor. The Ryzen 7000 mobile processors, including Phoenix and Dragon Range are expected to be launched in the first half of 2023, during AMD’s CES 2023 keynote.
