CPU-Z v2.10 Changelog Confirms Core-Config of Ryzen AI 300-series Processors
CPUID this week released the latest version of CPU-Z, and its change-log confirms the core-configurations of upcoming AMD Ryzen AI 300-series "Strix Point" processor SKUs. On paper, "Strix Point" packs a 12-core CPU based on the latest "Zen 5" microarchitecture, but there's more to this number. We've known since June 2024 that the chip has a heterogeneous multicore configuration of four full-sized "Zen 5" cores, and eight compacted "Zen 5c" cores. Only the "Zen 5" cores can reach the maximum boost frequencies rated for the chip, while the "Zen 5c" cores go a few notches above the base frequency, although it's expected that the gap in boost frequencies between the two core types is expected to slightly narrow compared to that between the "Zen 4" and "Zen 4c" cores in chips such as the "Phoenix 2."
The series is led by the AMD Ryzen AI 9 HX 375, an enthusiast segment chip that maxes out all 12 cores on the chip—that's 4x "Zen 5" and 8x "Zen 5c." This model is closely followed by the Ryzen AI 9 365, which AMD marked in its presentations as being simply a 10-core/20-thread chip. We're now learning that it has 4x "Zen 5" and 6x "Zen 5c," meaning that AMD hasn't touched the counts of its faster "Zen 5" cores. It's important to note here that "Zen 5c" is not an E-core. It supports SMT, and at base frequency, it has an identical IPC to "Zen 5." It also supports the entire ISA that "Zen 5" does.

The 375 page isn't live yet, but we already knew it'd be identical to the 370 because that's the maximum core config of this die.
Seems it was false positive.Was false positive, just update your definitions if you get the popup.
Now loads the CPU to only 0.328-0.368 V, while the older versions were jumping up and down between 0.2 and 1.2 V.
So far none of the leaked benchmarks for Strix seem impressive at all and Zen 5c cores are weaker than Zen 4 cores except maybe at very low power.
Also, Strix Point is looking pretty good in the 25W range and below, the reviews will be out soon enough and people will be testing it at lower wattage ranges, and also bear in mind that just because a product officially has a low wattage range does not mean that it's actually low power in real world usage and for a given performance. People like ("The Phawx" I think he goes by) will be testing this at various power settings, different limited speeds / RAM speed to show the sweetspot for performance at a given power level, or as is often the case, perhaps a little higher or lower is beneficial, either way, the NDA's are released on the 31st, so less than 10-days to wait and from what he has said, Strix is looking like it "could" be a graphics powerhouse at the bottom of the wattage range, and no-doubt you can tweak the chip for CPU performance above and beyond a simple BIOS max wattage setting if it's CPU performance not GPU performance you need most.
