AMD "Strix Halo" Processor Boosts up to 5.35 GHz, Geekbenched
AMD's upcoming "Strix Halo" mobile processor that features up to 16 "Zen 5" CPU cores and a powerful iGPU with 40 compute units, is beginning to surface in online benchmark databases. We've gone into the juicy technical bits about the processor in our older articles, but put simply, it is a powerful mobile processor meant to square off against the likes of the Apple M3 Pro and M3 Max. A chiplet-based processor, much like the upcoming "Granite Ridge" desktop processor and "Fire Range" mobile processor, "Strix Halo" features up to 16 full-sized "Zen 5" cores, as it uses up to two of the same "Eldora" CCDs as them; but wired to a large I/O die that contains the oversized iGPU, and an NPU, besides the memory controllers. The iGPU has 40 compute units (2,560 stream processors), and is based on the RDNA 3.5 graphics architecture, while the NPU is the same 50 TOPS-class unit carried over from "Strix Point."
A prototype HP laptop powered by a "Strix Halo" processor that uses a single 8-core "Zen 5" CCD, was spied on the web. This chip has eight full-sized "Zen 5" cores that share a 32 MB L3 cache. The iGPU on the I/O die has its own 32 MB Infinity Cache memory that cushions memory transfers. In our older reports, we speculated as to what the memory interface of "Strix Halo" would be. It turns out that the chip exclusively features a 256-bit wide LPDDR5X memory interface, which is double the bus width of "Strix Point." This is essentially what a "quad-channel DDR5" memory interface would be, and AMD is using a memory speed standard of at least LPDDR5X-8000. From the machine's point of view, this would be just a couple of hardwired LPDDR5X chips, or a pair of LPCAMM 2 modules. Back to the benchmarks, and we are shown a single-thread CPU score of 2099 to 2177 points, and a multithreaded score ranging between 5477 points to 13993 points. The laptop was tested with an unknown version and distribution of Linux. The CPU cores are shown boosting up to 5.35 GHz.
