Engineered for Integrity and Security
Every 9985WX processor is built using a Nickel-Plated Copper IHS and 24K Gold-Plated contacts to ensure flawless operation under heavy South African heat loads. Beyond the hardware, AMD PRO Technologies offer silicon-level protection. Features like AMD Memory Guard provide full-system memory encryption, shielding your proprietary architectural designs and data models from sophisticated physical and cyber threats.
Maximum Expandability on WRX90
By leveraging the WRX90 platform, the 9985WX allows users to bypass traditional desktop bottlenecks. With 128 PCIe 5.0 lanes, you can run multiple full-bandwidth GPUs, high-speed 100GbE networking, and NVMe RAID cards simultaneously. This makes it the ideal foundation for local AI development, where VRAM and data throughput are the primary drivers of success.
Note: This is a “WOF” (Without Fan) processor. A high-end liquid cooling solution or specialized sTR5 air cooler with a 350W TDP rating is mandatory. A discrete graphics card is required for display output.
