Intel Core Ultra 9 (Series 2) Desktop Processor 285 (AT8076806418)
- Architecture: Arrow Lake-S (15th Generation)
- Core Configuration: 24 cores (8 Performance-cores + 16 Efficient-cores)
- Threads: 24 threads (Similar to other Arrow Lake-S desktop processors, it does not utilize Hyper-Threading on E-cores, so the thread count matches the core count).
- Max Turbo Frequency: Up to 5.6 GHz (Intel Thermal Velocity Boost Frequency)
- Intel Turbo Boost Max Technology 3.0 Frequency: 5.5 GHz
- Performance-core Max Turbo Frequency: Up to 5.4 GHz
- Efficient-core Max Turbo Frequency: Up to 4.6 GHz
- Performance-core Base Frequency: 2.5 GHz
- Efficient-core Base Frequency: 1.9 GHz
- Socket: LGA 1851
- This is Intel’s new desktop socket for Arrow Lake-S and future processors.
- It maintains the same physical dimensions and cooler mounting hole spacing as LGA 1700, so most existing LGA 1700 coolers should be compatible.
- LGA 1851 exclusively supports DDR5 memory (up to 6400 MT/s) and offers more PCIe 5.0 lanes from the CPU (20 lanes: 16 for GPU, 4 for an M.2 SSD).
- Cache: 36 MB Intel Smart Cache (L3 Cache), 40 MB Total L2 Cache
- Processor Base Power (TDP): 65W
- Maximum Turbo Power (MTP): 182W
- Integrated Graphics: Intel Graphics (This model includes integrated graphics, providing display output without requiring a dedicated GPU).
- Graphics Base Frequency: 300 MHz
- Graphics Max Dynamic Frequency: 2.0 GHz
- GPU Peak TOPS (Int8): 8
- Graphics Output: DP2.1 UHBR20, HDMI2.1 FRL 12GHz, eDP1.4b
- Xe-cores: 4
- AI Acceleration: Includes Intel AI Boost (Neural Processing Unit – NPU) with 13 Peak TOPS (Int8) for accelerating AI workloads. The overall processor performance (CPU + GPU + NPU) can reach 36 Peak TOPS (Int8).
- Cooler: Not included
- Launch Date: Q1 2025 (January 2025)
- Key Features:
- High core and thread count (24 cores, 24 threads) for demanding multitasking and professional applications.
- Leading-edge clock speeds with Intel Thermal Velocity Boost for peak performance.
- Hybrid core architecture for optimal balance of performance and efficiency.
- Support for the latest DDR5 memory and PCIe 5.0 for high-bandwidth components.
- Integrated NPU for dedicated AI acceleration.
- Includes integrated graphics, offering display capabilities without a discrete GPU.
This processor is designed for enthusiasts, serious gamers, and professionals who require top-tier performance for applications like 4K gaming, complex content creation, video editing, 3D rendering, and AI development, all while benefiting from Intel’s latest architecture and integrated features.
