Official documents of Strix Point and Strix Halo leaked

AMD’s forthcoming next-generation Zen 5 architecture Ryzen mobile processors, codenamed Strix Point, along with a robust APU—Strix Halo, are poised for release possibly within this year or potentially at next year’s CES. Currently, an official document revealing limited information about them has been leaked.

The document was initially posted by a user named Izzukias and has since been removed, but was recorded by HKEPC. It explicitly details the specifications of Strix Point and Strix Halo. Strix Point will continue with a monolithic design, enhancing the CPU core count from 8 to 12, including 4 Zen 5 cores and 8 Zen 5c cores, with a total of 24MB L3 cache—16MB from the Zen 5 cores and 8MB from the Zen 5c cores. The GPU segment will upgrade from 12 to 16 groups of RDNA 3.5 CU, and the NPU capability will surge from the current 16 TOPS to 50 TOPS, with a TDP ranging from 45 to 65W. Memory support will remain consistent with current standards, accommodating DDR5-5600 and LPDDR5-7500.

The significantly larger Strix Halo will adopt a multi-chip design, incorporating two Zen 5 architecture CCDs, each boasting 16 cores and 32MB of L3 cache. It will feature an expansive integrated GPU on the SoC Die, equipped with 40 RDNA 3.5 CU units—surpassing the current RX 7600 XT’s 32 CU units. The GPU’s performance is expected to rival that of the RTX 4060 Laptop.

Interestingly, AMD has added a 32MB MALL Cache on the SoC Die, functioning similarly to the current Infinity Cache, which reduces the GPU’s reliance on memory bandwidth. Although the Strix Halo features a 256-bit memory controller, equating to quad-channel support for LPDDR5x-8000, this bandwidth would generally be insufficient for current GPUs. However, the inclusion of the MALL Cache should effectively alleviate any bandwidth constraints.

The NPU capability of Strix Halo reaches up to 60 TOPS, with a standard TDP of 70W. Manufacturers may adjust this based on the cooling design of the device, potentially elevating the CPU TDP to above 130W.
