2. Architectural Revolution
Custom Oryon Cores:
First mobile chip with 12-core CPU (4x Phoenix L1 + 8x Krake L2) based on ARM’s black hawk architecture.
3nm Process (TSMC N3E): Enables 5.0GHz peak clock speeds.
Hexagon NPU:
Dedicated Tensor Accelerator Unit for 70-100B parameter LLMs (e.g., Llama 3, Gemini Nano).
"AI Fusion": Combines CPU/GPU/NPU for complex tasks like real-time video generation.
3. On-Device AI Capabilities
LLM Support:
Runs Gemini Nano 2, Llama 3-70B (quantized), and Microsoft Phi-3 offline.
Context Window: 128K tokens → analyze 300-page PDFs on-device.
Generative AI Tools:
Stable Diffusion 3: 4K image generation in <3 seconds.
Live Video Translation: 100+ languages with lip-sync (no latency).
Camera & Gaming:
"Neural HDR": 18-bit ISP processes AI-enhanced 200MP photos.
Unreal Engine 5.4: Ray tracing at 120 FPS.
4. Target Devices & Competition
Flagship Launch Timeline:
Device Launch Date Xiaomi 15 Ultra October 2024 Samsung Galaxy S25 Ultra January 2025 OnePlus 13 December 2024 Rival Chips:
