8x H100 cluster rental on one physical machine.
GPU Rent Hub rents a dedicated 8× H100 SXM node, one single-tenant HGX server with all eight cards on an NVSwitch fabric, for $12,170 a month or $3,420 a week, paid in Bitcoin, Ethereum, USDT, USDC, Monero, Solana or Litecoin with no identity verification.
Nine node configurations, from an 8× RTX 4090 box at $2,810 a month to an 8× B200 HGX baseboard at $28,010.
What is a multi-GPU node, and how is it different from a cluster?
The word cluster gets used for two different products. Only one of them puts the cards on the same fabric.
The definition we work to
A multi-GPU node is one physical server rented to one tenant, with every GPU on a single baseboard and a direct fabric between the cards. A GPU Rent Hub 8× H100 SXM node is an NVIDIA HGX H100 baseboard: eight cards, 640 GB of HBM3, NVSwitch giving each card 900 GB/s to every other card, 160 vCPU, 2 TB of system RAM, 16 TB of local NVMe and two 100G ports, with root on the bare metal. It is not eight instances joined over Ethernet, and it is not a slice of a machine shared with someone else.
Why the distinction matters
A virtual cluster gives you eight cards that can each run a job. A real node gives you eight cards that can run one job together, and the difference shows up the moment you shard a model, because sharding means the cards talk to each other at every layer.
Everything on the node is yours: CPUs, RAM, NVMe, both uplinks and the fabric. Nothing of ours runs inside the operating system, and a node in stock deploys like any other instance.
How much does an 8x H100 cluster rental cost per month?
$12,170 a month for the eight-card HGX H100 node, $2.11 per GPU-hour. The rest of the range, mapped to the work it is bought for.

What is the difference between an NVSwitch node and a PCIe node?
Two groups of machines in the table above, and the gap between them is about thirty to one.
NVSwitch and NVLink
On the HGX platforms, every card reaches every other card at 900 GB/s on the H100 and H200 nodes, 1.8 TB/s on the B200 node and 600 GB/s on the A100 node. The MI300X platform does the same job with Infinity Fabric at 896 GB/s. No CPU sits in the path.
That bandwidth is what makes tensor parallelism realistic. Splitting a single model across eight cards means an all-reduce at every layer, hundreds of times per forward pass, and the cards spend their time waiting on that exchange rather than on arithmetic if the link is slow.
PCIe peer-to-peer
The L40S, RTX 5090 and RTX 4090 nodes have no NVLink. Cards talk over PCIe: about 32 GB/s in one direction on a Gen4 x16 link, about 63 GB/s on Gen5, shared with everything else crossing the root complex. Against the 900 GB/s of an H100 SXM card that is roughly a twenty-eighth of the bandwidth.
In practice that means one model per card. Data-parallel training, eight inference replicas behind a load balancer, eight render jobs: all fine. An 8-way tensor-parallel shard on a PCIe node is possible and slow, and the wall-clock time costs more than the node saved.
How much VRAM does a multi-GPU node need for your model?
Count bytes per parameter first. Almost every node decision falls out of that one number.
The sizing rule
Weights take 1 byte per parameter in FP8 and 2 bytes in BF16. To serve a model, add the KV cache and about 2 GB of runtime overhead. To fully fine-tune it with Adam in BF16, budget about 16 bytes per parameter: 2 for weights, 2 for gradients and 12 for optimiser state and the FP32 master copy. On the VRAM guide's figures a 70B needs 75 GB to serve in FP8, 145 GB in BF16, 156 GB for LoRA and 1,288 GB to fully fine-tune with activations counted. Only the last of those is a node-sized number.
What that buys you
A 70B model in BF16 needs 145 GB, so it will not fit on one 80 GB card but sits on an 8× H100 SXM node with 495 GB spare for batch and KV cache. A full fine-tune of the same model at 1,288 GB clears only on the 8× B200 or the 8× MI300X. Everything else here needs LoRA or ZeRO offload, as set out on the GPU for fine-tuning page.
LoRA on a 70B is not one of these jobs. At 156 GB the VRAM guide puts it on a single MI300X at $1,590 a month, so a node costs you seven times the money and an evening of device maps for nothing.
Ranked by gigabytes per dollar the order is blunt: the MI300X node is $7.45 per GB-month, the L40S node $9.74, the A100 node $11.14, the H100 node $19.02. The cheap ones are cheap for reasons, ROCm on one and no NVLink on the other.
How does the multi-GPU discount work, and does it stack?
5% at two cards, 8% at four, 10% at eight, applied to the single-card price. It stacks with the prepaid term discount.
| H100 SXM, one host | List price | Discount | You pay | Per GPU-hour |
|---|---|---|---|---|
| 1 card | $1,690 | none | $1,690/mo | $2.35 |
| 2 cards | $3,380 | 5% | $3,211/mo | $2.23 |
| 4 cardsNVLink, half baseboard | $6,760 | 8% | $6,220/mo | $2.16 |
| 8 cardsFull HGX node, NVSwitch | $13,520 | 10% | $12,170/mo | $2.11 |
| 8 cards, 3 months prepaid10% then 5% | $40,560 | 14.5% | $34,685total | $2.01 |
| 8 cards, 6 months prepaid10% then 10% | $81,120 | 19% | $65,718total | $1.90 |
The floor is $1.90 per GPU-hour for eight NVSwitched H100 SXM cards, against $2.35 for a single card on a rolling month. Payment does not change with the size of the order: fund a balance in BTC, ETH, USDT, USDC, XMR, SOL or LTC and the term is drawn from it, no card and no identity document. See how crypto payment works, what no-KYC GPU hosting means, and why a monthly term beats an hourly meter.
Can you rent 16 to 64 GPUs across several nodes?
Yes, with InfiniBand between the nodes, quoted per case rather than sold from the catalogue.
Tell sales the shape
GPU count, model, region, term, and InfiniBand HDR at 200 Gb/s or NDR at 400 Gb/s. Write to sales.
Quote and lead time
16 to 64 GPUs, priced against the node rates above. Lead time 2 to 6 weeks, depending on the fabric.
50% at order
Half the first term up front, in any of the seven coins. That reserves the hardware.
50% at hand-over
The balance once the fabric passes bring-up and you have root. No identity check at any step.
Networking between instances in a region
Instances in the same region can share a private VLAN: layer 2 between your machines with no public hop, $25 a month, included on every 8-way node. That is the tool for a storage box feeding four 8× A100 nodes.
It is not a substitute for InfiniBand. A VLAN rides the same 100G Ethernet as everything else: fine for data loading and checkpoints, wrong for gradient exchange at every step.
When is a multi-GPU node the wrong thing to rent?
If your job fits on one card, a node is a waste of money. An 8× RTX 4090 node is $2,810 a month against $390 for a single card, and a 13B model in FP8 is 22 GB all in, weights, cache and overhead. Eight cards pay for themselves only with eight streams of work, or a model that does not fit.
If you need eight cards for two days, use an hourly provider: a week of an 8× H100 node is $3,420 whether you run it for six hours or 168. And if the constraint is memory rather than throughput, a single H200 with 141 GB or an MI300X with 192 GB often removes the need for a node.
Rent a node when
The model does not fit on one card, the run lasts weeks, you need eight replicas behind one address, or the job is sharded and needs 900 GB/s between cards.
Rent single cards when
The jobs are independent, the load is unpredictable, or you want to test on one H100 SXM before committing to eight.
