AMD Strix Halo “FP11” APU Reference Platform Spotted With Massive 128 GB Memory Config

AMD’s Strix Halo APUs have been making waves, and the latest shipping logs hint at some impressive memory capabilities. Let’s dive into the details of this enthusiast-tier APU platform.

Massive Memory Pools

The recent shipping logs reveal that AMD’s Strix Halo APUs could feature memory pools of up to 128 GB. Yes, you read that right! Most high-end desktop PCs today don’t even reach 64 GB, so this is quite remarkable. However, such large memory configurations also mean higher costs for these high-end devices based on the Strix Halo platform.

FP11 Platform and TDPs

The Strix Halo APUs are designed for the FP11 (BGA) platform and will come in TDPs ranging from 55W to 130W. AMD seems to be pushing the chips to their limits by utilizing the full untapped TDPs. Enthusiasts can look forward to chips that support these high TDPs, maximizing the APU’s potential.

LPDDR5x and MALL Cache

Considering the expected 40 compute units in the iGPU, the Strix Halo might opt for LPDDR5x memory. While 128 GB of LPDDR5x would be pricey, more reasonable 32 GB and 64 GB solutions are likely within the enthusiast price range. Additionally, the onboard graphics will benefit from the 32 MB MALL cache.

Powerful Features

Let’s take a quick look at the expected features of the AMD Ryzen AI HX Strix Halo:

  • Zen 5 Chiplet Design
  • Up to 16 Cores
  • 64 MB of Shared L3 cache
  • 40 RDNA 3+ Compute Units
  • 32 MB MALL Cache (for iGPU)
  • 256-bit LPDDR5X-8000 Memory Controller
  • XDNA 2 Engine Integrated
  • Up to 60 AI TOPS
  • 16 PCIe Gen4 Lanes
  • Expected 2H 2024 Launch
  • FP11 Platform (55W-130W)

Impressive Graphics

The integrated graphics chip boasts 40 compute units, surpassing even the Radeon RX 7600 XT. With a 128-bit LPDDR5x memory configuration, we can expect around 120-140 GB/s of bandwidth. AMD might widen the interface to keep costs lower while still closing the bandwidth gap with discrete RDNA 3 GPUs.

In summary, the Strix Halo APUs represent an exciting evolution in APU technology, combining Zen 5, RDNA 3.5, and XDNA 2 cores. We eagerly await more details from AMD themselves.
