AMD Begins Driver Support for RDNA 3.5 “GFX1151” GPUs for High-End Strix Halo APUs

Introduction

AMD, the renowned semiconductor company, has recently initiated driver support for its RDNA 3.5 “GFX1151” GPUs. These high-performance graphics processors are set to power the premium Strix Halo APUs designed for notebooks. In this blog post, we delve into the details of these upcoming GPUs, their architecture, and what they mean for the future of mobile computing.

The Strix Halo APUs

The next-generation Strix APUs from AMD will be available in two variants: a monolithic design and a chiplet offering. Both versions are expected to feature the refined RDNA 3.5 integrated GPUs. Let’s explore the specifics of each variant:

1. Monolithic Design (GFX 1150)

  • Architecture: The monolithic design integrates a GFX 1150 (16 Compute Units) GPU.
  • CPU Cores: Up to 12 cores in a hybrid configuration (combining Zen 5 and Zen 5C cores).
  • L3 Cache: 32 MB of shared L3 cache.
  • Memory Controller: 128-bit LPDDR5X memory controller.
  • AI Engine: Integrated with an AI engine capable of approximately 25 TOPS (tera-operations per second).
  • Expected Launch: Second half of 2024.

2. Chiplet Design (GFX 1151)

  • Architecture: The chiplet variant features a GFX 1151 (40 Compute Units) GPU.
  • CPU Cores: Up to 16 cores.
  • L3 Cache: 64 MB of shared L3 cache.
  • Memory Controller: 256-bit LPDDR5X memory controller.
  • AI Engine: Integrated with an AI engine capable of approximately 50 TOPS.
  • Expected Launch: Second half of 2024.

RDNA 3.5 Architecture

The RDNA 3.5 architecture represents a significant leap forward. Here’s what we know about it:

  • Performance: These GPUs are expected to deliver better performance compared to their predecessors.
  • Efficiency: RDNA 3.5 cores are optimized for improved APU efficiency.
  • Zen 5 Cores: Strix Point APUs will incorporate the latest Zen 5 CPU cores.
  • RDNA 3.5 GPU Cores: The integrated GPUs will be based on the latest RDNA 3.5 architecture.

Conclusion

AMD’s Strix Halo APUs promise exciting advancements in mobile computing. With powerful GPUs, efficient cores, and cutting-edge architecture, these APUs are poised to elevate the performance of notebooks. Keep an eye out for their official launch in the coming months!
