Latest Pricing Trends: Vast.ai and RunPod, At the Forefront of Price Competition
The cloud GPU market is dynamic, with prices fluctuating daily due to supply and demand shifts and the introduction of new models. Let’s examine the latest pricing trends from both providers.
Consumer-Grade GPUs (RTX Series)
RTX series GPUs are popular among many AI developers for their affordability and high performance.
| Model | Provider | On-Demand Price ($/hr) | Availability |
|---|---|---|---|
| RTX 3090 | Vast.ai | 0.123 | Medium |
| RTX 3090 | RunPod | 0.22 - 0.27 | High |
| RTX 4080 | Vast.ai | 0.1637 | Medium |
| RTX 4080 | RunPod | 0.27 - 0.28 | High |
| RTX 4090 | Vast.ai | 0.3424 | Medium |
| RTX 4090 | RunPod | 0.34 | High |
Vast.ai offers the RTX 3090 at $0.123/hr, which is approximately 44% cheaper than RunPod’s lowest price of $0.22/hr. While Vast.ai maintains an edge for the RTX 4080, the RTX 4090 sees fierce competition, with Vast.ai at $0.3424/hr and RunPod at $0.34/hr, practically identical. While RunPod tends to have higher availability, Vast.ai often presents more attractive pricing.
Data Center GPUs (A100, H100, L40/L40S)
For demanding AI workloads, data center-grade GPUs like the A100 and H100 are essential.
| Model | Provider | On-Demand Price ($/hr) | Availability |
|---|---|---|---|
| A100 | Vast.ai | 0.6015 | Medium |
| A100 | RunPod | 1.00 - 1.39 | High |
| L40 | Vast.ai | 0.457 | Medium |
| L40 | RunPod | 0.69 | High |
| L40S | Vast.ai | 0.8022 | Medium |
| L40S | RunPod | 0.79 | High |
| H100 SXM | Vast.ai | 2.2027 | Medium |
| H100 SXM | RunPod | 2.69 | High |
| H100 | Vast.ai | 2.3396 | Medium |
| H100 | RunPod | 2.59 | High |
| H100 PCIe | RunPod | 1.99 | High |
Vast.ai’s A100 is notably cheaper at $0.6015/hr, approximately 40% less than RunPod’s lowest A100 price of $1.00/hr. This makes Vast.ai a highly attractive option for users planning large-scale A100 deployments. For L40/L40S, Vast.ai’s L40 has seen a significant price drop (from $0.58 to $0.46, a -20.9% decrease), and Vast.ai’s L40S ($0.8022/hr) is now competitive with RunPod’s L40S ($0.79/hr), largely due to Vast.ai cutting its L40S price by 25.3% from $1.07 to $0.80.
In the H100 series, Vast.ai has newly added the H100 SXM at $2.2027/hr. Meanwhile, RunPod offers the H100 PCIe at a highly competitive $1.99/hr, making it currently the most affordable option among H100 series. When considering cutting-edge GPUs like the H100 SXM or H100, RunPod’s H100 PCIe might offer superior cost performance. It’s crucial to compare detailed specifications alongside pricing. Past price fluctuations show Vast.ai’s H100 increased by 16.7% from $2.00 to $2.34, underscoring the importance of staying updated in this dynamic market.

Build Your Own PC vs. Cloud GPU: A Break-Even Analysis
When considering high-performance GPUs, many users ponder whether to build their own PC or opt for cloud GPU services. Let’s analyze the break-even point using the RTX 4090 as an example.
- Self-built PC with RTX 4090: Approximately ¥600,000 (roughly $4,000 at ¥150/$1)
- Current cheapest cloud RTX 4090 rate: $0.34/hr
The utilization time required for cloud RTX 4090 usage to surpass the initial investment of a self-built PC is approximately 11,765 hours ($4000 / $0.34/hr). This translates to about 1 year and 4 months of continuous operation. Unless you require continuous GPU usage for extremely long periods, the flexibility and lower upfront investment of cloud GPUs offer overwhelming advantages. Especially for specific project durations or when experimenting with multiple GPU models, cloud services are clearly superior.
Furthermore, building your own PC involves hidden costs beyond the initial investment, such as electricity bills, cooling systems, maintenance, and OS/driver setup. Cloud GPUs eliminate these operational concerns, allowing you to pay only for what you use, when you need it, often leading to better overall cost-effectiveness.
