| A100 | $0.7377 | $1.00 (min) | Vast.ai cheaper (but Vast.ai’s price rising) |
| H100 PCIe | $2.1335 | $1.99 | RunPod cheaper |
| H100 SXM | $2.2693 | $2.69 | Vast.ai cheaper |
| H100 | $1.9926 | $2.59 | Vast.ai cheaper |
| L40 | $0.5778 | $0.69 | Vast.ai cheaper |
| L40S | $1.2074 | $0.79 | RunPod significantly cheaper |
Key Analysis Points
- RTX Series: For individual developers and small projects, the popular RTX 3090, 4080, and 4090 models generally see Vast.ai offering more competitive rates than RunPod. The price difference is particularly noticeable for RTX 3090 and 4080.
- A100: The workhorse for AI workloads, the A100, is offered by Vast.ai at $0.7377, providing better value than RunPod’s minimum price of $1.00. However, it’s crucial to note that Vast.ai’s A100 prices have recently seen a significant increase.
- H100: For the cutting-edge H100, RunPod is slightly cheaper for the PCIe version at $1.99 compared to Vast.ai’s $2.1335. However, Vast.ai holds the advantage for the SXM and generic H100 models. For high-end GPUs, prices between providers are often neck-and-neck, with leadership shifting over time.
- L40/L40S: Vast.ai offers a cheaper L40, but the L40S tells a different story. Vast.ai’s L40S has risen significantly to $1.2074, making RunPod’s $0.79 an overwhelmingly more affordable option.
Recent Price Fluctuations and Market Trends
Over the past few weeks, both providers have experienced notable price shifts:
- Vast.ai’s A100 price surged: From $0.40 to $0.74, an increase of +83.7%. This might indicate demand for A100 outstripping supply.
- Vast.ai’s L40S also surged: From $0.63 to $1.21, a +92.0% increase. This also suggests heightened demand.
- Vast.ai’s H100 decreased: From $2.39 to $1.99, a -16.6% drop. This could be due to price adjustments for H100 with the emergence of newer GPUs like H200.
- Vast.ai’s RTX 4090 decreased: From $0.37 to $0.33, a -10.9% drop. The RTX series generally faces intense competition, leading to more volatile pricing.
- RunPod’s A100 and RTX 3090 decreased: With drops of -14.4% to -28.1% and -18.5% respectively, RunPod is strengthening its competitive edge for certain models.
These fluctuations illustrate the complex interplay of market supply and demand, the introduction of new GPUs, and strategic decisions by providers. Staying informed with the latest data is key to optimizing costs.
Self-Built PC vs. Cloud GPU: Break-Even Analysis for RTX 4090
The debate between a self-built PC and cloud GPU is constant when considering high-performance GPU integration. Let’s calculate the break-even point using the RTX 4090 as an example:
- Reference price for an RTX 4090 self-built PC: Approximately $4,000 (roughly 600,000 JPY at $1=150 JPY)
- Current cheapest cloud RTX 4090 hourly rate: Vast.ai’s $0.3259/hr
- Break-even point for self-built vs. cloud at cheapest rate: Approximately 12274 hours (about 511 days, or 1 year and 5 months)
This calculation suggests that if you plan to utilize an RTX 4090 almost 24/7 for over 1 year and 5 months, a self-built PC might offer better long-term cost-effectiveness. However, cloud GPUs provide significant advantages:
- No upfront investment: No need for a large lump sum of capital.
- Flexible scaling: Rent the exact number of GPUs you need, on an hourly basis.
- No maintenance: No worries about hardware failures, upgrades, or power consumption.
- Diverse GPU options: Access high-end GPUs like A100 or H100 that might be out of reach for a self-built setup.
For short-term projects, experimental research, or sudden large workloads, cloud GPUs are overwhelmingly superior. For long-term, predictable computational needs, a self-built PC might be worth considering.

Further Considerations for Provider Selection
Beyond just price, the following factors are crucial for making an informed provider choice:
- Availability: Is the required GPU consistently available? Our data suggests RunPod generally boasts “High” availability, while Vast.ai often shows “Medium”. This can be a critical differentiator.
- Support System: Speed and quality of support in case of issues.
- Ecosystem and Tools: Pre-built images, API ease of use, and community activity.
- Regions and Latency: Availability of regions close to your data.

Conclusion: Smart Choices Pave the Way for Future Success
Vast.ai and RunPod are both compelling cloud GPU providers, each with distinct strengths. Vast.ai maintains excellent price competitiveness for RTX series and some A100 models, but has seen significant price increases in models like the L40S. RunPod, on the other hand, is competitive with H100 PCIe and L40S, and generally boasts higher availability.
The market is constantly evolving, and the cheapest provider today may not be tomorrow. Success hinges on continually monitoring the latest pricing information, considering your project requirements, duration, and budget.
