AMD's future 'Medusa Halo' APUs could use LPDDR6 RAM — new leak suggests Ryzen AI MAX 500 series could have 80% more memory bandwidth
Summary
AMD's upcoming Medusa Halo APU, expected between 2027 and 2028, promises cutting-edge performance with Zen 6 CPU cores and RDNA 5 graphics. Recent leaks indicate potential support for LPDDR6 memory, achieving impressive bandwidths of 460.8 GB/s.
Key Insights
What is an APU and why is memory bandwidth important for Medusa Halo?
An APU (Accelerated Processing Unit) is a system-on-chip that integrates CPU and GPU cores on a single die, ideal for laptops and handhelds. High memory bandwidth is crucial for Medusa Halo's powerful RDNA 5 iGPU and AI workloads like LLM inference, as it determines how quickly data can be accessed by the shared unified memory.

What is LPDDR6 and how does its bandwidth compare to current APU memory?
LPDDR6 is the next-generation low-power DRAM standard for mobile devices, supporting speeds up to 14,400 MT/s. On Medusa Halo's 256-bit bus, it delivers 460.8 GB/s bandwidth—an 80% increase over Strix Halo's 256 GB/s LPDDR5X—potentially rising to 691.2 GB/s with a rumored 384-bit bus.
