AMD Ryzen Z2 Extreme to Feature a 3+5 Core Configuration
The second generation of AMD Ryzen Z-series processors for handheld gaming consoles, will be led by the Ryzen Z2 Extreme. There will also be an affordable Ryzen Z2 (non-Extreme). We've known for some time that the Z2 Extreme is based on the 4 nm "Strix Point" monolithic silicon, with some optimization (the highest bins to facilitate the best energy efficiency); but now we have a few more details thanks to a leak by Golden Pig Upgrade. AMD's engineering effort with the Z2 Extreme will be to give the console the most generational performance uplift from the iGPU, rather than the CPU.
The "Strix Point" silicon features a significantly updated iGPU from the previous-generation "Phoenix." It's based on the more efficient RDNA 3.5 graphics architecture, which is better optimized for LPDDR5 memory; and comes with 16 compute units (CU), compared to 12 on the "Phoenix." The Ryzen Z2 Extreme will come with all 16 CU enabled. The CPU is where some interesting changes are planned. The "Strix Point" silicon features a dual-CCX CPU, one of these contains four "Zen 5" CPU cores sharing a 16 MB L3 cache, while the other features eight "Zen 5c" cores sharing an 8 MB L3 cache. For the Ryzen Z2 Extreme, AMD is going with an odd 3+5 core configuration. What this means is that the Ryzen Z2 Extreme will have 3 "Zen 5" cores, and 5 "Zen 5c" cores. The L3 cache on the CCX with "Zen 5" cores has been reduced to 8 MB in size. On paper, this is still an 8-core/16-thread CPU with 16 MB of L3 cache (same as "Phoenix,") but now you know that there's more going on.
