Features Comparison

Hot Aisle

AMD MI300X Fleet
Dell PowerEdge XE9680 servers with 8x 192GB AMD Instinct MI300X GPUs and Intel Xeon CPUs.
Minute-Level Billing
Transparent published MI300X rates, with self-service VMs and dedicated 8-GPU bare metal both metered by the minute through Stripe.
Automation Below Kubernetes
NetBox-backed inventory plus automated SONiC networking, PXE boot, host setup, and current ROCm drivers, so orchestration is not the first layer.
Isolated KVM Instances
NUMA-balanced KVM virtual machines with direct GPU access and private isolated networking to avoid noisy neighbors.
High-Speed Fabric
8x400G RoCEv2 per chassis plus 100G internet and unlimited bandwidth.
Ready-to-Use Images
Ubuntu options with ROCm, Docker, and optional K8s/Slurm/Ray installs via cloud-init.

Spheron

Multi-provider marketplace
Access GPU capacity from multiple cloud providers and certified data centers from one account, without separate signups per provider
Per-minute billing
Instances are billed by the minute rather than rounded up to the hour, past a 20-minute minimum runtime (60 minutes for a 2x AMD MI300X)
Fast provisioning
NVIDIA instances are typically ready in under two minutes with no approval workflow or provisioning queue
Unified billing and cost tracking
Compute spend across every connected provider is tracked in a single dashboard
Full root access instances
Each VM or bare metal instance includes NVMe SSD storage, network bandwidth and full root access, with a dedicated IP on NVIDIA instances
Supplier matchmaking
Spheron sources large clusters, specific hardware and InfiniBand configurations from its partner data center network, with a typical quote turnaround of 24-48 hours

Pros & Cons

Hot Aisle

Advantages

Self-service MI300X VMs with transparent published rates metered by the minute, no sales call required
Dense XE9680 nodes with 8x400G RoCEv2 for multi-server scaling
Credit card to running compute in under a minute, with public IP and firewall control included
100G internet with unlimited bandwidth plus included IPv4/IPv6 addresses

Considerations

Single public region (Grand Rapids, MI) limits locality options
AMD-only GPU lineup today; MI355X is reservation-only for now
VMs top out at 4 GPUs; 8-GPU configurations are offered only as dedicated bare metal

Spheron

Advantages

One account and dashboard spans several GPU clouds, avoiding per-provider lock-in
Per-minute billing past a short minimum runtime, with no contract or long-term commitment
Wide NVIDIA range from RTX 4090 through B300 plus the AMD MI300X, with GB200, GB300 and R100 available to reserve
Spot instances run the same hardware at up to 50% off dedicated rates

Considerations

Capacity is supplied by third-party data centers, so hardware, regions and operational experience vary by partner
Spot instances are interruptible and can be reclaimed when demand returns
Large clusters, custom configurations and reserved capacity go through sales rather than self-service
