AI Chips Surge: Storage CPU Revaluation

Enhanced Key Takeaways

• •The surge in storage demand is driven by the transition from traditional NAND/DRAM cycles to high-bandwidth memory (HBM3e/4) and CXL-based memory expansion, which are essential for reducing latency in large-scale AI model training.
• •CPU manufacturers are pivoting toward 'AI-native' architectures, integrating dedicated matrix multiplication units and enhanced vector processing capabilities to handle the orchestration and data-preprocessing bottlenecks that GPUs cannot efficiently manage.
• •The Chinese AI supply chain is undergoing a strategic shift toward 'localization of compute,' where domestic firms are prioritizing the integration of RISC-V based high-performance CPUs to mitigate risks associated with potential export restrictions on x86/ARM architectures.

Technical Deep Dive

• •DeepSeek V4 utilizes a Mixture-of-Experts (MoE) architecture that significantly reduces the computational overhead per token, allowing for more efficient inference on standard CPU-heavy server clusters.
• •CXL (Compute Express Link) 3.0 implementation is becoming the standard for memory pooling, enabling CPUs to access massive, shared memory tiers that are critical for RAG (Retrieval-Augmented Generation) applications.
• •Integration of AVX-512 and AMX (Advanced Matrix Extensions) in modern server CPUs is enabling them to handle non-GPU AI workloads, such as database indexing and complex logic flow, with up to 3x performance gains over previous generations.
