AMD Raphael-H for Notebooks to Offer 16 Cores/32 Threads, Granite Ridge w/ 3nm, 6nm Zen 5 Hybrid Core Arch

AMD will be doubling down on core counts with Raphael, at least on the mobile front. We’re looking at core counts of up to 16 (32 threads) with a TDP of up to 45W. This was shared earlier today by @Greymon55, a well-reputed source on AMD hardware. According to him, we’ll be seeing two mobile Zen 4 lineups, namely Phoenix-H and Raphael-H. While both will leverage the 5nm Zen 4 core architecture, the former will be limited to 8 cores and 16 threads, and a TDP of under 40W.

Raphael-H, on the other hand, will double the core count to 16, while also using the standard 45W TDP mark seen in high-performance notebook CPUs. In addition to these Zen 4 mobile families, the source also provided some initial data on AMD’s Zen 5 plans.

It looks like the chipmaker will be gradually sliding into a hybrid core architecture. This will be initiated by Granite Ridge (sometime in late 2023/early 2024) with a mixture of 3nm and 6nm Zen 5 cores. The former will likely be used as the high-performance core cluster with the latter being a low-power cluster. Meanwhile, Strix Point will be the first “true” hybrid core APU with 3nm Zen 5 cores and 5nm Zen 4c cores. Once again, the former will be used as the high-performance cluster, and the latter acting as a low-power cluster. Strix Point should arrive sometime in 2024.
