AMD’s Next-Gen “big.LITTLE” Hybrid CPU: 4+8 Cores and an iGPU Faster than the PS5?

AMD’s Ryzen 8000 “Strix Point” APU has been spotted in action for the first time, courtesy of Performance DataBases. The hybrid-core processor will be the first true big.LITTLE design from Team Red, employing the next-gen Zen 5 and Zen 5c (Zen 5 “dense”) core architectures alongside an RDNA 3.5 graphics engine. The CPU side will feature 12 cores, with 4 Zen 5 “P-cores” and 8 Zen 5c “E-cores”, all with SMT support, bringing the thread count up to 24.

Both cores have 80KB (I+D) of L1 cache per core. The P-cores come with 1MB of L2 cache per core, while the E-cores feature two chunks of 1MB cache distributed equally amongst two four core clusters. The L3 cache is pegged at 8MB, substantially lower than the traditional Zen CCD. We assume this is to save die space, similar to most Ryzen APUs.

The clock speeds on Strix Point aren’t correctly reported. We are looking at an average active clock of 2.12GHz and an effective clock of 25MHz, which are obviously incorrect. On the GPU side, we’ve got a potent iGPU with 1,024 shaders spread across 16 CUs. These ALUs are said to be based on the RDNA 3.5 graphics architecture, leveraging features of RDNA 3 as well as 4.

The shared video memory is reported as 512MB of GDDR6 SDRAM, courtesy of the upgraded Infinity Fabric interconnect. The reported bandwidth is 16GT/s, but take it with a grain of salt. The Ryzen 8000 processor is paired with 32GB of LPDDR5 quad-channel memory configuration. This indicates two memory DIMMs clocked at 6,400MT/s with a 17 (CL) latency.

The AMD Ryzen 8000 “Strix Point” processors are expected to be revealed at CES 2024 alongside or after the Zen 5-based Ryzen 8000 desktop processors.
