Understanding Billing

With Ranch Computing, you are billed only for the actual machine resources consumed (GHz.h for CPU or OB.h for GPU). As long as your project is queued (and not actively rendering), you can:

• Change its priority to move it up the queue.
• Remove it from the queue without any charges.

💰 Pricing and Ranch Credits (RC)

• 1 RC = 1€ by default.
• Discounts may apply based on your top-ups (e.g., prepaid refills with volume discounts or promotional offers).

🔧 CPU Billing: GHz.h

The cost of CPU projects is based on:

1. The number of GigaHertz per hour (GHz.h) consumed.
2. The selected priority (CPU-Low, CPU-High, etc.).

What Is a GHz.h?

Each processor has a frequency in GHz, indicating its processing power. To calculate consumption, we use GHz.h (GigaHertz per hour), which combines:

• The number of cores (or threads).
• The frequency in GHz.
• The rendering time in hours.

Example with an AMD 42-Core Server (2.45 GHz)

• Number of cores: 42 cores
• Frequency: 2.45 GHz
• Calculation for 2 hours of rendering: 42 cores × 2.45 GHz × 2 h = 205.8 GHz.h (Total GHz.h consumption for this server over the specified duration.)

Cost Calculation

The cost depends on:

1. The number of GHz.h consumed (here: 205.8 GHz.h).
2. The hourly rate of the selected priority (e.g., CPU-Low).

Example with CPU-Low priority (rate: 0.011 RC/GHz.h):

• 205.8 GHz.h × 0.011 RC/GHz.h = 2.26 RC (Cost for 1 server over 2 hours of rendering.)

If 30 identical machines render simultaneously:

• 2.26 RC × 30 machines = 67.8 RC (Total cost for 30 equivalent servers over 2 hours of rendering.)

Cost by Priority (Non-Exhaustive List)

Priority	Price per GHz.h	Cost for 205.8 GHz.h
CPU-Low	0.011 RC	2.26 RC
CPU-High	0.015 RC	3.09 RC

🎮 GPU Billing: OB.h

The cost of GPU projects is based on:

1. The OctaneBench score (OB) of the graphics cards used.
2. The rendering time.
3. The selected priority (GPU-Low, GPU-High, etc.).

What Is an OB.h?

The OctaneBench score measures the computing power of a graphics card for GPU rendering. The higher the score, the more powerful the card is for rendering tasks.

Example with a Server Equipped with 2 × RTX 3090

• Total OB score: ~1300 points (based on OctaneBench 2020/2025). This score represents the combined power of the 2 cards.
• Calculation for 30 minutes of rendering (0.5 h): 1300 OB × 0.5 h = 650 OB.h (This value represents the OB.h consumption for this server over the specified duration.)

Cost Calculation

The final cost depends on:

1. The number of OB.h consumed (here: 650 OB.h).
2. The hourly rate of the selected priority (e.g., GPU-Low).

Example with GPU-Low priority (rate: 0.005 RC/OB.h):

• 650 OB.h × 0.005 RC/OB.h = 3.25 RC (Cost for 1 server over 30 minutes of rendering.)

If 10 identical machines render simultaneously:

• 3.25 RC × 10 machines = 32.5 RC (Total cost for 10 servers over 30 minutes of rendering.)

Cost by Priority (Non-Exhaustive List)

Priority	Price per OB.h (in RC)	Cost for 650 OB.h
GPU-Low	0.005 RC	3.25 RC
GPU-High-24	0.010 RC	6.5 RC
