AMD Strix Point and Halo specs have been leaked

According to HKEPC, a 144-page document featuring specifications of AMD Ryzen CPUs based on Strix Point and Strix Halo series has been leaked.



The document confirms the specs of both products, neither of which has been released yet. AMD is yet to unveil the full specs of its next-gen APU series based on Zen5 architecture, so this leak certainly tells us a lot more.

Starting with Strix Point (listed as STX), we have 12 Zen5 cores and 24 threads. The L2 cache is mentioned as 12MB total and L3 cache size is 24 MB. This APU will feature 8 WGP (Work Group Processors) based on RDNA3.5 architecture, which should translate into 16 Compute Units. The CPU and GPU specs are an upgrade over Phoenix/Hawk Point featuring 8 Zen4 cores and up to 8 RDNA3 CUs.

The document confirms that XDNA2 AI-Accelerator is to offer 50 TOPS (trillion operations per second), which is indeed more than 3 times faster than Hawk Point (16 TOPS). Furthermore, we learn that the APU will support DisplayPort 2.1 specs up to UHBR10 transmission mode. Strix Point is a 45 to 65W TDP APU, and it will use an FP8 socket.

Moving on to Strix Halo (STX Halo), the document lists 16 cores and 32 threads based on Zen5 architecture. Similarly to STX, it would feature 1MB per core, which means 16MB of L2 cache and 32MB of L3 cache per CCD. Presumably, this APU will feature two CCDs, each with 8 Zen5 cores. The Strix Halo will also feature 32MB of MALL Cache, which should function similarly to Infinity Cache.

The APU is to support XDNA2 processor for AI, offering up to 60 TOPS. Worth noting that the figure is just for the NPU part, not the CPU & GPU. The Halo will feature support for up to DP 2.1 UHBR20 mode.

The Halo has support for 256-bit LPDDR5X-8000 memory, while Point supports up to LPDDR5x-7500 judging from the slides. According to the specs, the Halo has a 70W TDP by default, but it is mentioned that it will work up to 130W. The Halo uses FP11 socket.
