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. (wonderfulengineering.com)
