OCP Summit Reveals AMD Data Center New Strategy

At the 2025 OCP (Open Compute Project) Global Summit, AMD announced the Helios rack-scale AI hardware platform, AMD’s first complete rack-scale solution integrating compute, memory, interconnect, and cooling in a single system. Helios is deeply optimized for AI workloads, directly challenging NVIDIA’s dominant position in the data center AI accelerator market. AMD emphasizes Helios advantages in memory capacity, maintenance convenience, and energy efficiency, providing enterprises and cloud service providers with high-performance alternatives beyond NVIDIA.

Helios Platform Technical Architecture

Rack-Scale Integration Design

Helios adopts rack-scale design philosophy, integrating traditionally dispersed compute, storage, and network components into a standard 42U rack:

High-Density Compute Nodes: A single 42U rack can accommodate 64-128 compute nodes, each node equipped with 8-16 MI450 Instinct GPUs and 2-4 EPYC processors. Total single-rack capacity exceeds 1,000 GPUs’ computational power.

Unified Cooling System: Adopts liquid cooling technology, directly channeling coolant into GPU and CPU modules, with cooling efficiency 3-5 times higher than traditional air cooling. This allows AMD to increase chip power limits, releasing higher performance.

Modular Maintenance: Nodes use hot-swap design; failed components can be replaced without system downtime. Compared to NVIDIA solutions requiring entire cabinet offline maintenance, Helios significantly reduces downtime and maintenance costs.

MI450 Instinct GPU

Helios’s core is AMD’s latest MI450 Instinct GPU (codename “Antares”), based on CDNA 4 architecture:

Computational Performance:

  • FP64 (double precision floating point): 100 TFLOPS
  • FP32 (single precision floating point): 200 TFLOPS
  • FP16/BF16 (half precision): 1.6 PFLOPS
  • INT8 (integer): 3.2 POPS

These figures make MI450 approach or exceed NVIDIA H200 GPU performance in large language model training.

Memory System: Each MI450 equipped with 288GB HBM3e (High Bandwidth Memory), bandwidth reaching 8 TB/s. Compared to NVIDIA H200’s 141GB HBM3, AMD’s memory capacity advantage exceeds double.

Interconnect Technology: Adopts fourth-generation Infinity Fabric interconnect, supporting GPU-to-GPU point-to-point communication with bandwidth reaching 900 GB/s. Combined with AMD Infinity Architecture, achieves high-performance distributed training.

Energy Efficiency Optimization: Uses TSMC 3nm process, TDP (Thermal Design Power) 750W. Though higher than NVIDIA H200’s 700W, considering memory capacity advantage, power consumption per GB memory is lower.

EPYC Processor Integration

Fifth-Generation EPYC “Turin”: Helios features 96-core EPYC 9005 series processors, handling system management, data preprocessing, I/O control. Zen 5 architecture provides strong single-thread performance and AI acceleration instructions.

CXL Memory Expansion: Supports CXL 3.0 (Compute Express Link), allowing CPU and GPU to share memory pools, reducing data transfers, improving large model training efficiency.

Security Features: Integrates AMD Secure Processor and SEV-SNP (Secure Encrypted Virtualization), protecting AI workloads in cloud multi-tenant environments, preventing data leaks.

50% Memory Capacity Advantage Analysis

Why Memory is AI Bottleneck

Model Scale Explosion: GPT-4 has approximately 1.76 trillion parameters; GPT-5 expected to exceed 10 trillion. Storing 10 trillion parameters at FP16 precision requires 20TB memory. Even with 288GB per GPU, still requires 70+ GPUs to load complete model.

Batch Processing Requirements: Training simultaneously processes thousands of data samples (batch size), each sample containing thousands of tokens. Large batch size improves training efficiency but exponentially increases memory requirements.

Intermediate Result Caching: Deep neural network training requires storing each layer’s activation values for backpropagation. Deeper models require more caching, potentially exceeding parameters themselves.

Helios Memory Advantage

Single-Node Capacity: An 8-GPU MI450 node totals 2.3TB memory, compared to 8-GPU H200 configuration (1.1TB), double the capacity. This allows single nodes to train larger models or larger batch sizes.

Reduced Communication Overhead: Larger memory allows models to partition into fewer pieces, reducing cross-node communication frequency and communication latency’s impact on training speed.

Inference Throughput: During inference, large memory allows simultaneous loading of multiple model versions or serving more concurrent requests, improving throughput and resource utilization.

Comparison with NVIDIA Vera Rubin

NVIDIA Vera Rubin: NVIDIA’s anticipated 2026 Vera Rubin platform, based on Blackwell architecture GB300 GPU, approximately 192GB memory per chip.

AMD Helios Advantage: Helios’s 288GB memory is 50% more than Vera Rubin; this gap is critical in large model training. Larger memory may allow same tasks with fewer GPUs, reducing total cost of ownership.

Potential NVIDIA Counterattack: NVIDIA may adopt HBM4 memory in Vera Rubin, increasing to 256GB or higher. Memory capacity race will continue escalating.

Serviceability and Operational Efficiency

Traditional Data Center Pain Points

Failure Downtime Costs: AI training tasks may last weeks to months; single GPU failure can interrupt entire task. Traditional solutions require entire cabinet offline for repairs, with downtime losses calculated in tens to hundreds of thousands of dollars per hour.

Labor-Intensive Maintenance: Data centers require substantial technical staff for monitoring, diagnostics, component replacement. Labor costs account for 20-30% of data center operational expenses.

Component Replacement Cycles: GPUs, power supplies, fans have limited lifespans. Large-scale data centers may experience dozens of failures daily, with maintenance work ongoing.

Helios Serviceability Improvements

Hot-Swap Design: All compute nodes, power modules, network switches support hot-swap. Technicians can replace failed components while system runs; other nodes continue working.

Fault Isolation: Helios platform automatically detects failed nodes, migrating workloads to healthy nodes, isolating fault areas. This fault-tolerant design maximizes system availability.

Remote Diagnostics: Integrates remote management tools for diagnosing issues, updating firmware, adjusting configurations over network, reducing on-site maintenance needs.

Predictive Maintenance: AI algorithms analyze component temperature, voltage, error rates to predict potential failures, replacing components proactively to avoid unplanned downtime.

Operational Cost Savings

AMD estimates Helios serviceability improvements can reduce data center operational costs by 15-25%:

Reduced Downtime: Fault repair time drops from hours to minutes, annual availability increases from 99.9% to over 99.99%.

Lower Labor Requirements: Automated diagnostics and remote management reduce on-site technician needs, per-GPU labor costs down 30%.

Reduced Spare Hardware: Fault-tolerant design lowers spare hardware requirements, optimizing capital expenditure by 10-15%.
