A practical starting estimate is $20 per month for Vultr Cloud Compute: Vultr’s OBS-on-Ubuntu guide specifies at least 2 vCPUs, 4 GB RAM, 80 GB storage and 3 TB of bandwidth, and Vultr lists a plan matching the CPU, RAM and bandwidth at that monthly price. A continuous stream can use more than the included bandwidth, so the final bill depends on bitrate and Vultr’s current billing terms.
Vultr’s monthly starting point
Vultr’s OBS and Ubuntu streaming-server guide, updated April 1, 2025, calls for at least 2 virtual CPUs, 4 GB of RAM, 80 GB of storage and 3 TB of bandwidth for its example. Vultr’s Cloud Compute pricing page lists a 2-vCPU, 4-GB plan with 3 TB of bandwidth at $20 per month. That is the clearest documented baseline for the guide’s particular setup—not a guarantee that every streaming workload will run well on that size.
| Option or calculation | Amount | What it means |
|---|---|---|
| Vultr Cloud Compute, 2 vCPUs and 2 GB RAM | $15/month; 3 TB bandwidth listed | A lower listed price, but below the 4 GB RAM minimum in Vultr’s streaming-server guide. |
| Vultr Cloud Compute, 2 vCPUs and 4 GB RAM | $20/month; 3 TB bandwidth listed | The better-supported starting point for the guide’s OBS/Ubuntu example. |
| 10 Mbps transmitted continuously for 30 days | About 3.24 decimal TB | Calculated from bitrate and time; not a provider quote or observed bill. |
| Illustrative overage on that 10-Mbps example | About 240 GB, or $2.40 at $0.01/GB | Approximation against a 3-TB allowance; actual charges depend on Vultr metering and allocation rules. |
These are figures listed on Vultr’s pricing and FAQ pages when retrieved in 2026, not a promise that prices or terms will remain unchanged. Check the current plan details before deploying. Vultr’s FAQ says hourly billing and plan-specific monthly caps apply, and that a stopped instance continues to incur charges until it is destroyed.
Why bandwidth can add to the bill
A server sending a live feed to YouTube produces continuous outbound traffic. At a constant 10 Mbps, the arithmetic is 10,000,000 bits per second × 2,592,000 seconds in 30 days ÷ 8 bits per byte, or about 3.24 decimal TB. That is slightly above a 3-TB allowance. Vultr’s FAQ says it measures charged bandwidth on outbound traffic, does not charge for inbound traffic, and lists $0.01 per GB for usage beyond quota. Applying that rate to the simple example gives about $2.40 above 3 TB; the actual invoice follows Vultr’s metering and billing rules.

- WHY CHOOSE CORE I3-10110U - Better single-core performance: The Core i3-10110U has a higher peak boost clock (4.1 GHz) compared to the Ryzen 3 4300U and the Intel Alder Lake N150 series, making it better for tasks that rely on fast single-core performance (e.g., web browsing, office apps). Better multi-thread performance via Hyper-Threading: the Core i3-10110U offers better performance in multi-threaded workloads compared to the Ryzen 3 4300U, especially for light productivity work and multitasking.
- 16GB RAM MEMORY & 512GB SSD STORAGE - GMKtec Nucbox G3 PRO mini pc is prebuilt with 16GB DDR4 RAM SO-DIMM DUAL CHANNEL, you will enjoy a speedier experience with Built-in 512GB M.2 Hard Drive. Our mini desktop pc boots up in seconds, work on multiple browser tabs, software applications and quickly transfers files. There is a primary slot and secondary expansion storage. Primary slot is M.2 2280 PCIE/SATA and secondary slot is M.2 2242 SATA .
- RICH INTERFACE - Nucbox core i3 mini computer is equipped with USB 3.2*4,up to 5Gbps/S, HDMI(4K@60Hz)×2, 3.5mm Audio Jack. Supports WiFi 6, and Gigabit Ethernet RJ45 2.5GbE network connectivity, Bluetooth 5.2. This Mini PC supports multiple device connection and can be used with servers, monitoring equipment, office equipment, displays, projectors, televisions, etc.
- 4K DUAL SCREEN DISPLAY - Mini desktop computer is equipped with upgraded Intel Graphics(max 1000MHz), supports 4K video playback and AV1 decoding, connect the pc with a projector as a home theatre, enjoy a variety of entertainments. Two HDMI 2.0 ports allows you to multi-task efficiently on two 4K@60Hz displays.
- UPGRADED COOLING FAN - The G3 PLUS has upgraded the cooling fan to reduce fan noise and thermals. We are using an upgraded thermal paste as well to help reduce heat on the CPU.
Do not multiply the server’s outbound usage by the number of viewers. YouTube says it transcodes an incoming live stream into multiple output formats for viewers, so the VPS-to-YouTube feed is distinct from YouTube’s viewer delivery.
Bitrate changes the bandwidth estimate
YouTube’s live encoder recommendations provide useful reference points for estimating feed traffic. For H.264, YouTube recommends 8 Mbps at 720p/30 fps, 14 Mbps at 1080p/30 fps and 17 Mbps at 1080p/60 fps. At a fixed bitrate, higher continuous bitrate means more outbound data over the same period; variable-bitrate content and real-world metering can change the total.

- Use the actual configured output bitrate—not just the resolution—to estimate server egress.
- For a rough monthly estimate, multiply Mbps by 0.324 to get decimal TB over 30 days. For example, 10 Mbps × 0.324 is about 3.24 TB.
- Compare that estimate with the plan’s included bandwidth, then verify how Vultr applies its quota and overage rate.
YouTube recommends RTMPS, constant bitrate (CBR), and a 2-second keyframe interval that does not exceed 4 seconds. These are YouTube ingest recommendations, not a guarantee that a particular VPS can encode a given resolution without performance problems.
Compute needs depend on what the server does
The $20 plan is a defensible starting estimate for the cited OBS/Ubuntu example, but compute needs are workload-specific. Vultr’s guide advises reducing output resolution or upgrading if CPU usage is high. A server encoding video or rendering complex OBS scenes can demand more compute than one relaying pre-encoded media. The guide does not establish a universal CPU requirement, so monitor the actual workload rather than assuming the baseline will suit every channel.

Those statements apply to that named product; they are not included terms for ordinary Cloud Compute. See Vultr’s Broadcaster Marketplace documentation for its details.
What to check before deploying
- Confirm the current Cloud Compute price, included bandwidth, hourly billing and monthly cap on Vultr’s pricing page.
- Use the 4-GB RAM guide requirement as a starting point for that OBS/Ubuntu setup; choose based on the encoder and scene workload you actually plan to run.
- Estimate outbound traffic using the stream’s configured bitrate and intended uptime, then account for possible overage under Vultr’s current FAQ terms.
- Budget for the instance to continue costing money if it is stopped; Vultr says charges stop only when the instance is destroyed.

- 【AMD Ryzen 7330U】 – The Efficiency-Tuned Powerhouse，AMD Ryzen 7330U (Zen 3, SMT, 4C/8T) in KAMRUI P2 mini PC crushes rivals: Intel i3-10110U (2C/4T, 2019) and N95 (4 efficiency cores, no HT, single-channel memory). Vs predecessor Ryzen 3 4300U (4C/4T): ~50% faster single-core, ~46% multi-core, 8MB L3 cache (vs 4MB). Beats both Intel chips hugely in multi-core, making heavy multitasking, coding, data work smooth at just 15W TDP. High-end power in a cool, efficient box.
- 【AMD Radeon Graphics】– Triple 4K Vision & Fluidity，The integrated Radeon Graphics (based on the modern Vega architecture with 6 CUs) is a visual beast, outclassing the iGPU offerings from both AMD's prior generation and Intel. The Intel UHD Graphics (i3-10110U/N95) struggles with single-channel memory and low execution units, crippling its gaming performance and barely handling basic 4K video without stuttering. While the older Radeon Vega 5 (4300U) was decent, our 7330U's Radeon Graphics (6 CUs) pushes the boundaries, delivering higher graphics clock speeds (up to 1.8GHz) and significantly better rendering capabilities. It can drive triple 4K@60Hz displays with zero lag, edit photos/videos.
