Comparison of upcoming x86 unified memory systems

AMD is set to dominate the unified memory market with its upcoming Medusa Halo architecture, slated for summer 2027. This system will feature a 50% performance improvement over the current Strix Halo, achieved by expanding memory channels from 4 to 6 and adopting LPDDR6 memory. The result is a massive bandwidth range of 460-690 GB/s, far outpacing competitors. Medusa Halo will be built on Zen 6 cores and RDNA5 graphics, making it ideal for AI and compute-heavy tasks.

Intel's Nova Lake AX, expected in early 2026, will offer up to 341 GB/s using LPDDR5X or possibly LPDDR6 memory. Meanwhile, AMD's Gorgon Halo refresh, launching this summer, delivers 273 GB/s with LPDDR5X-8533—a 15% boost over Strix Halo's 256 GB/s. These systems highlight a rapid evolution in unified memory, crucial for AI inference and high-bandwidth applications. AMD's aggressive roadmap suggests a clear lead in memory performance by 2027.
