AMD Strix Halo APUs are expected to be very powerful in terms of computing as they get AVX512 support and have been added to ROCm.
AMD Strix Halo APUs reportedly deliver amazing performance and will have a significant bandwidth increase per CCX
The upcoming AMD Strix Halo APUs are expected to deliver terrific performance as per the latest leak. The Strix Halo lineup is highly anticipated as it is going to be the first APU that will feature a whopping 40 compute units for its RDNA 3.5-based "GFX1151" iGPU. According to the latest leak, the Strix Halo is getting readied for its 2025 launch and is reportedly offering great performance.
The new leak comes from the X user @hjc4869(David Huang), who posted some pics, which reveal that the GFX1151 has received official support for the ROCm. ROCm(Radeon Open Compute) is an open-source platform for GPU computing, which provides powerful tools for developers. The AMD GFX1151 is the code name for the integrated graphics for Strix Halo based on the RDNA 3.5 GPU architecture.
With such support, AMD's Strix Halo APUs will be able to offer powerful gaming and professional workload performance, which haven't been witnessed on a mainstream mobile chip till now. The leaker also revealed that the GFX1151 was also recently added to the compiler framework, LLVM Table Description with 192K VGPR(Vector General Purpose Registers), which suggests that the iGPU will have improved software and programming support.
今天跟群友聊到gfx1151查了下才发现strix halo上那个RDNA3.5前不久在LLVM td里被加上了192K完整VGPR的描述，而且ROCm各种库最近都偷偷加上了strix halo的官方支持……结合之前看到它的CPU Geekbench 5跑分疑似有完整AVX512宽度和每CCX两倍带宽，这下笔记本甚至平板能当超算用了？😆 pic.twitter.com/jKmWGVy1on

One notable point he mentions is Strix Halo's Geekbench 5 performance. While he didn't reveal the score, he did point out that it is so powerful that laptops and tablets can become supercomputers with it. Plus the full AVX512 width support to increase the CPU's register size and twice the bandwidth for each CCX is also reported to be the case with Strix Halo. This will allow the CPU to run large amounts of data in parallel while remaining power-efficient.
AMD Ryzen AI HX Strix Halo Expected Features:
- 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
- 2H 2024 Launch (Expected)
- FP11 Platform (55W-130W)
As mentioned by the user @AnhPhuH(Hoang Anh Phu), with the added ROCm support, the existing Strix Point will also benefit via porting. All in all, the Strix Halo looks quite serious in terms of performance. We have already reported before that Strix Halo will be twice as big as the Strix Point and will feature up to 120W of TDP. It's expected that Strix Halo will be first used in ASUS ROG Flow Z13 2025 PC tablet.
As per the leak by Hoang Anh Phu, AMD is set to reveal the Strix Halo at CES 2025 along with the budget offering Krackan Point. CES 2025 will be held in January and will be the event where AMD will also be launching the Ryzen 9000X3D processors.
