Overview
How the ClusterMAX™ Rating System works
What is ClusterMAX™?
The ClusterMAX™ Rating System provides a comprehensive framework for evaluating GPU cloud providers based on critical dimensions of cloud infrastructure quality and service delivery. Our independent analysis helps you make informed decisions when selecting a GPU cloud provider.
Unlike simple performance benchmarks or cost comparisons, ClusterMAX™ evaluates the complete ecosystem of GPU cloud services, from security and compliance to orchestration capabilities and long-term reliability.
Why ClusterMAX™ Matters
The GPU cloud market has exploded with options, making it increasingly difficult for organizations to choose the right provider. Traditional evaluation methods often focus on narrow metrics like price per GPU hour or peak performance, missing critical factors that determine real-world success.
Our Evaluation Process
We combine hands-on testing, documentation review, and real customer feedback to build a complete picture of each provider.
We deploy real workloads on each provider's infrastructure, testing everything from basic GPU performance to complex multi-node training jobs, including network performance, storage throughput, and reliability under load.
We analyze each provider's technical documentation, security certifications, SLA commitments, and compliance frameworks to understand their capabilities and limitations.
We collect and analyze feedback from actual users across different industries and use cases, providing insight into real-world performance and support quality.
Rating Tiers
After evaluating a Neocloud against our 10 key criteria (Security, Lifecycle, Orchestration, Storage, Networking, Reliability, Monitoring, Pricing, Partnerships, and Availability) we assign one of these ratings. This is a relative rating system: each provider is assessed against its peers, and Gold and Platinum providers rise to the top by introducing features and functionality that others do not have.
The best GPU cloud providers in the industry. They consistently excel across evaluation criteria, are proactive and innovative, and maintain an active feedback loop with their users. In practice they command a pricing premium because their total cost of ownership is better even when the raw $/GPU-hr is higher.
Strong performance across all evaluation categories with some opportunities for improvement. Gold-tier providers may have small gaps or inconsistencies but are responsive to feedback. A great choice that generally wins deals, especially with the best $/GPU-hr and availability on the customer timeline.
An adequate offering with noticeable gaps compared to Gold or Platinum. Some users will not consider a Silver provider despite attractive pricing and availability. There is clear room for improvement, and we encourage adopting industry best practices to catch up to peers.
Fulfills our minimum criteria, and the last tier we directly recommend. Common issues include inconsistent support, subpar networking, unclear SLAs, limited Kubernetes/Slurm integration, or less competitive pricing. Several providers here are making real effort to catch up.
Based on hands-on testing, these providers can quickly rise to Bronze or Silver by fixing one or more critical issues, such as offering only older GPUs, missing basic security attestation (SOC 2, ISO 27001), misconfiguring key server features (leaving PCIe ACS enabled, or failing to enable GPUDirect RDMA), or charging for GPU hours during cluster creation or hardware downtime.
An interesting service we are excited about but cannot verify yet: not launched publicly, sold out with no plans to add capacity, government-only, or otherwise untestable. We keep a "trust but verify" approach until we can complete hands-on testing.
Continuous Updates
The GPU cloud landscape evolves rapidly, with new providers entering the market and existing ones continuously improving their offerings. ClusterMAX™ ratings are updated regularly to reflect these changes, ensuring our evaluations remain current and relevant.
