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.

Impossible Cloud

Bare Metal GPU Clusters
Dedicated NVIDIA systems without virtualization, from 2-GPU PCIe servers to 8-GPU SXM nodes and GB300 NVL72 racks, with InfiniBand or RoCE interconnect on larger clusters.
Published Term Pricing
Each listed cluster shows a per-GPU-hour rate for every available contract term, from one month to 60 months, along with region, node count and availability date.
Public Pricing Feed
The GPU offer list is published as an unauthenticated JSON feed, regenerated daily.
S3-Compatible Object Storage
Object storage compatible with the AWS S3 API, with no egress or API-call fees and no minimum storage duration.
Managed Inference
OpenAI-compatible inference endpoints for open-weight models (DeepSeek, Qwen, Kimi, GLM, gpt-oss, Nemotron), billed per million tokens; currently in early access.
Compliance
Headquartered in Germany with ISO 27001 certification and GDPR-aligned data handling in European data centers.

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

Impossible Cloud

Advantages

Per-GPU-hour rates published for every listed cluster and contract term
GPU compute and S3 object storage from one provider, so data and compute can sit in the same region
Dedicated bare metal hardware without virtualization
German headquarters and European data residency options

Considerations

No on-demand hourly rate; all GPU capacity is sold on committed terms
Many listed clusters have a future availability date rather than immediate capacity
Some listings show region, configuration or node count only on request
