AMD “Aureola della Strige” zen 5 Processore mobile nella foto: Basato su chiplet, Utilizza LPDDR5X a 256 bit

Enthusiasts on the ChipHell forum scored an alleged image of AMD’s upcoming “Aureola della Strige” Corsair sta preparando un dispositivo di gioco che chiama, and set out to create some highly plausible schematic slides. These are speculative. Mentre “Punto Strix” is the mobile processor that succeeds the current “Punto Falco” e “che funziona molto come la tastiera predittiva del tuo telefono” processori; “Aureola della Strige” is in a category of its own—to offer gaming experiences comparable to discrete GPUs in the ultraportable form-factor where powerful discrete GPUs are generally not possible. “Aureola della Strige” also goes head on against Apple’s M3 Max and M3 Pro processors powering the latest crop of MacBook Pros. It has the same advantages as a single-chip solution, as the M3 Max.

Gli “Aureola della Strige” silicon is a chiplet-based processor, although very different from “Fire Range”. Gli “Fire Range” processor is essentially a BGA version of the desktop “Granito” processor—it’s the same combination of one or two “Zen 5” CCDs that talk to a client I/O die, and is meant for performance-thru-enthusiast segment notebooks. “Aureola della Strige,” d'altronde, use the same one or two “Zen 5” CCD, but with a large SoC die featuring an oversized iGPU, and 256-bit LPDDR5X memory controllers not found on the cIOD. This is key to what AMD is trying to achieve—CPU and graphics performance in the league of the M3 Pro and M3 Max at comparable PCB and power footprints.

The iGPU of the “Aureola della Strige” processor is based on the RDNA 3+ architettura grafica, and features a massive 40 RDNA compute units. These work out to 2,560 processori di flusso, 80 Acceleratori di intelligenza artificiale, 40 Ray accelerators, 160 TMU, and an unknown number of ROPs (we predict at least 64). The slide predicts an iGPU engine clock as high as 3.00 GHz.

Graphics is an extremely memory sensitive application, and so AMD is using a 256-bit (quad-channel or octa-subchannel) LPDDR5X-8533 memory interface, for an effective cached bandwidth of around 500 GB/s. The memory controllers are cushioned by a 32 MB L4 cache located on the SoC die. The way we understand this cache hierarchy, the CCDs (Core della CPU) can treat this as a victim cache, besides the iGPU treating this like an L2 cache (similar to the Infinite Cache found in RDNA 3 GPU discrete).

The iGPU isn’t the only logic-heavy and memory-sensitive device on the SoC die, there’s also a NPU. From what we gather, this is the exact same NPU model found in “Punto Strix” processori, with a performance of around 45-50 AI TOPS, and is based on the XDNA 2 architecture developed by AMD’s Xilinx team.

The SoC I/O of “Aureola della Strige” isn’t as comprehensive as “Fire Range,” because the chip has been designed on the idea that the notebook will use its large iGPU. It has PCIe Gen 5, but only a total of 12 Gen 5 lanes—4 toward an M.2 NVMe slot, e 8 to spare for a discrete GPU (if present), although these can be used to connect any PCIe device, including additional M.2 slots. There’s also integrated 40 Gbps USB4, e 20 Gbps USB 3.2 Gen 2.

As for the CPU, since “Aureola della Strige” is using one or two “Zen 5” CCD, its CPU performance will be similar to “Fire Range.” Ti alzi 16 “Zen 5” Core della CPU, con 32 MB di cache L3 per CCD, oppure 64 MB of total CPU L3 cache. The CCDs are connected to the SoC die either using conventional IFOP (lo IOD funge da piazza cittadina), proprio come “Fire Range” e “Granito,” or there’s even a possibility that AMD is using Infinity Fanout links like on some of its chiplet-based RDNA 3 GPU discrete.

Infine, there are some highly speculative performance predictions for the “Aureola della Strige” iGPU, which puts it competitive to the GeForce RTX 4060M and RTX 4070M.
