Intel Core Ultra 9 (Series 2) Desktop Processor 285T (AT8076806417)
- Architecture: Arrow Lake-S (15th Generation), built on a 4nm-class (Intel 20A or TSMC 3nm equivalent) manufacturing process. It features a hybrid architecture with “Lion Cove” Performance-cores and “Skymont” Efficient-cores.
- Core Configuration: 24 Cores (8 Performance-cores + 16 Efficient-cores)
- Threads: 24 Threads (Arrow Lake-S desktop processors do not utilize Hyper-Threading on E-cores, so the thread count matches the core count).
- Max Turbo Frequency:
- Overall Max Turbo Frequency: Up to 5.4 GHz
- Performance-core Max Turbo Frequency: 5.3 GHz (or 5.4 GHz depending on specific boost behavior)
- Efficient-core Max Turbo Frequency: 4.6 GHz
- Base Frequency:
- Performance-core Base Frequency: 1.4 GHz
- Efficient-core Base Frequency: 1.2 GHz
- Socket: FCLGA1851 (also commonly known as LGA 1851). This is Intel’s new desktop socket, maintaining physical compatibility with LGA 1700 coolers.
- Cache:
- 36 MB Intel Smart Cache (L3 Cache)
- 40 MB L2 Cache
- Power:
- Processor Base Power (PBP): 35W
- Maximum Turbo Power (MTP): 112W
- This significantly lower base power compared to non-T models makes it highly suitable for small form factor PCs and builds prioritizing energy efficiency and quieter operation.
- Integrated Graphics: Intel Graphics (often referred to as Arc Xe-LPG Graphics)
- Graphics Base Frequency: 300 MHz
- Graphics Max Dynamic Frequency: Up to 2.0 GHz
- Xe-cores: 4
- GPU Peak TOPS (Int8): 8
- Graphics Output: DP2.1 UHBR20, HDMI 2.1 FRL 12GHz, eDP1.4b
- Supports up to 4 displays.
- AI Acceleration: Includes Intel AI Boost (Neural Processing Unit – NPU)
- NPU Peak TOPS (Int8): 13
- Total Processor Performance: Up to 35 TOPS (combining CPU, GPU, and NPU)
- Supports AI Software Frameworks like OpenVINO™, WindowsML, DirectML, ONNX RT, WebNN.
- Memory Support:
- Max Memory Size: Up to 192 GB (or 256 GB, depending on specific motherboard support)
- Memory Types: Up to DDR5 6400 MT/s
- Max # of Memory Channels: 2 (Dual-channel)
- ECC Memory Supported: Yes
- PCI Express Revision: 5.0 and 4.0
- Max # of PCI Express Lanes: 24 (CPU only), configurable (e.g., 1×16+2×4, 2×8+2×4, 1×8+4×4).
- Cooler: As an OEM/Tray product, it may or may not include a cooler. Even if a basic cooler is provided, for optimal sustained performance of a Core Ultra 9, a high-performance aftermarket cooling solution (like a robust air cooler or an AIO liquid cooler) is generally recommended, especially given its burst MTP of 112W.
- Launch Date: Q1 2025 (January 2025)
- Recommended Customer Price (MSRP): Around $620.00 – $811.00 (Pricing can vary by region and retailer).
Key Features:
- Exceptional Power Efficiency: Its 35W Processor Base Power delivers Core Ultra 9 performance in systems with strict power or thermal constraints, making it perfect for SFF builds, mini-PCs, and workstations where efficiency is paramount.
- High Core and Thread Count: 24 cores / 24 threads provide robust multitasking capabilities and strong performance for professional applications and demanding workloads.
- Integrated AI Acceleration: The dedicated NPU, a hallmark of the Core Ultra series, significantly boosts performance for AI-enhanced software and features.
- Modern Platform Support: Full support for DDR5 memory and PCIe 5.0 ensures compatibility with the latest high-speed components.
- Integrated Graphics: The included Intel Graphics provides capable visual performance for productivity, media consumption, and light gaming without needing a discrete GPU.
This processor is an excellent choice for users who demand top-tier performance but require a CPU with a low base power for energy efficiency, quiet operation, or compact system designs, particularly for advanced productivity, content creation, and AI workloads.
