    • Vast.ai H100 PCIe: $2.337/hr (New offering)
    • Vast.ai H100 (SXM): $2.5889/hr (Slight increase of +5.2% MoM)
    • RunPod H100 PCIe: $1.99/hr
    • RunPod H100 SXM: $2.69/hr

    For H100s, RunPod’s H100 PCIe offers a more budget-friendly option compared to Vast.ai. While Vast.ai holds a slight edge for SXM models, the prices are largely comparable. This indicates fierce competition in the top-tier GPU segment.

  • NVIDIA A100: A widely adopted high-performance GPU in the AI/ML sector.

    • Vast.ai A100: $0.6681/hr (Significant price drop)
    • RunPod A100: $1.00/hr to $1.39/hr (Multiple price points, significant price drop)

    Vast.ai offers an undeniably lower price for the A100, making it the clear winner in terms of pure cost performance. While RunPod has also lowered its prices, Vast.ai’s lowest offering remains unmatched, though RunPod often boasts higher availability.

Desktop-Class GPUs: RTX Series, L40/L40S, A6000

  • NVIDIA RTX 3090: Popular for its excellent cost-performance ratio.

    • Vast.ai RTX 3090: $0.103/hr (Significant price drop)
    • RunPod RTX 3090: $0.22/hr to $0.27/hr

    Vast.ai’s RTX 3090 price is incredibly competitive. While RunPod has also reduced its prices, Vast.ai offers nearly half the cost, making it advantageous for smaller projects with budget constraints.

  • NVIDIA RTX 4080 / 4090: Latest generation of high-performance desktop GPUs.

    • Vast.ai RTX 4080: $0.1356/hr
    • RunPod RTX 4080: $0.27/hr to $0.28/hr
    • RunPod RTX 4090: $0.34/hr

    In the RTX 40 series, Vast.ai provides a lower price for the RTX 4080. RunPod offers the RTX 4090 at $0.34/hr, making it a compelling option if you require the latest and most powerful consumer-grade GPU in the cloud.

  • Other Options (L40/L40S, A6000):

    • RunPod L40: $0.69/hr
    • RunPod L40S: $0.79/hr
    • RunPod A6000: $0.33/hr

    RunPod also provides a diverse range of specialized GPUs such as the L40 and A6000, making it easier to find the perfect GPU for specific workloads.

Overall Insights

If cost is your top priority, Vast.ai is highly attractive due to the significant price reductions on A100s and RTX 3090s. Conversely, if you prioritize the lowest H100 PCIe pricing, access to RTX 4090, a wider variety of GPUs like L40/L40S, and stable availability, RunPod presents an excellent choice. Understanding the strengths of both providers and aligning them with your project’s requirements and budget is crucial.

DIY PC vs. Cloud GPU: Breakeven Point Analysis

Many may wonder, “Wouldn’t it be cheaper to build my own high-performance PC?” Let’s examine the breakeven point between a DIY PC and cloud GPUs.

  • Estimated Cost for a DIY PC with RTX 4090: Approximately ¥600,000
  • Current Lowest Cloud RTX 4090 Hourly Rate: $0.34/hr (RunPod)

Assuming an exchange rate of ¥150 per dollar, $0.34/hr translates to ¥51/hr.

DIY PC Breakeven Point at Cloud’s Lowest Price: ¥600,000 ÷ ¥51/hr = 11,765 hours

This means that to recover the initial investment of a DIY PC equipped with an RTX 4090, you would need to use a cloud GPU for approximately 11,765 hours (about 490 days, or about 4 years if used 8 hours daily). If your usage exceeds this duration, a DIY PC might offer cost advantages. However, cloud GPUs come with numerous benefits:

  • No Upfront Investment: Eliminates the need for expensive hardware purchases.
  • Flexibility: Pay only for what you use, when you need it.
  • Maintenance-Free: No worries about hardware failures, upgrades, or power consumption.
  • Scalability: Instantly scale GPU resources up or down as needed.
  • Access to Latest GPUs: Get access to cutting-edge GPUs (like H100s) that may be difficult to acquire for a DIY setup.

Considering these points, cloud GPUs are overwhelmingly advantageous, especially for short-term projects, experimenting with specific GPU models, or irregular usage patterns. Unless you have a long-term, highly consistent usage plan or require advanced specialized knowledge, cloud GPUs represent a highly attractive option for most AI/ML developers.
