Leak suggests AMD Strix Point does feature a hybrid architecture

Intel moved towards a hybrid architecture in recent years, offering desktop processors with a mix of performance and efficiency cores. Rumours have claimed that AMD will eventually do the same and now, we have our first piece of evidence of that. New CPU-Z screenshots appear to show an AMD Strix Point processor in operation. 

Performancedatabases (via VideoCardz) says that it has the first screenshots showcasing a running AMD Strix Point APU. In one of the pictures, we see CPU-Z running, but it doesn't fully recognise the CPU. Still, it can tell you which instruction set is suitable and how big the CPU is. On the other hand, the HWiNFO image shows that the processor in question is a Strix (Point?) chip based on the 4nm process node with a 45W TDP.

The HWiNFO picture in particular also shows a few details about clock speeds, but it's clear that the data is wrong. Not only does it show a minimum and boost clock speed of 6.375GHz, but also a base clock speed of 8.8GHz, which doesn't make much sense. Still, it's important to note that the information read by HWiNFO suggests the upcoming chips will support AVX2 and AVX512 instructions.

Moreover, the pictures let us see that the CPU has four Zen5 cores and eight smaller Zen5c cores. Both types of cores allow hyper-threading, something that Intel's E-cores don't. Also, it looks like the size of the L1 data cache is 48KB per core, while the size of the instruction cache is 32KB per core. Also, each P-core has 1MB of L2 cache, while the E-cores seem to be grouped in clusters of four cores, with each group sharing 1MB of L2 cache between themselves. The amount of L3 cache on both programs contradicts each other, with CPU-Z showing 16MB and HWiNFO showing 8MB.

KitGuru says: These two screenshots back up the idea that Strix Point APUs are currently being tested. However, it's important to note that these CPUs are still engineering samples, and as such, it will take some time before we see them running on any commercially available devices.
