AMD Strix Halo Processor Crystals with Huge iGPU Shown in Detailed Photos

Enthusiasts have published a detailed image of the 4-nm crystal of the new AMD Strix Halo (Ryzen AI 300 Max) mobile processor, which clearly shows all the components of the chip. Along with the image, a detailed description of what elements are contained in the processor was presented.

The new Strix Halo processors use a chiplet design. They consist of two CCD blocks (each measuring 67.07 mm²) with Zen 5 computing cores, as well as a huge I/O die (307.58 mm²) that houses integrated graphics with 40 compute units based on the RDNA 3.5 architecture and a powerful XDNA2 AI accelerator (NPU) with a performance of 50 TOPS (trillion operations per second). The total area of ​​the processor is 441.72 mm².

The Strix Halo memory subsystem supports a 256-bit interface (eight 32-bit controllers) for LPDDR5, delivering up to 256 GB/s of bandwidth. The processor has 32 MB of shared LLC (Last Level Cache) and 8 MB of L2 cache per CCD.

The chip’s images also show some design features and optimizations for the mobile platform. In particular, AMD has reduced the distance between the CCD blocks in Strix Halo by 2 mm compared to the CCDs of its desktop processors. The chip also features through-silicon-via (TSV) structures, which suggest compatibility with 3D V-Cache technology, although AMD itself has not officially confirmed plans to implement this technology in these processors.

Block I/O Die AMD Strix Halo

In addition to 40 integrated graphics units and the XDNA2 NPU, the I/O Die chiplet provides support for PCIe 4.0 x16 lanes, is equipped with USB4, USB 3.2, USB and USB 2.0 controllers, as well as two Media Engines with full support for H.264, H.265 and AV1 and one Display Engine. The latter is responsible for encoding the iGPU output frame into various connector formats (such as DisplayPort, eDP, HDMI).

One of the first mobile devices with Strix Halo processors will be the powerful Asus ROG Flow Z13 gaming tablet, which will go on sale on February 25. Pre-orders for the device are already being accepted. The new product has already been in the hands of reviewers, who highly appreciated the computing and graphics capabilities of the new Ryzen AI 300 Max processors.
