A dedicated server for live streaming needs enough processing power and network capacity to deliver video without buffering. However, requirements change depending on your setup. Sending one feed to YouTube is very different from hosting streams for hundreds of viewers. Here is how to size your server.
Dedicated Server for Live Streaming: Start With the Workload
First, decide what the server will do. A relay forwards an existing encoded stream. A transcoding server creates different resolutions and bitrates. A delivery server sends video directly to viewers. These tasks place different demands on hardware and bandwidth.
If you stream only to YouTube or another platform, that platform usually handles viewer delivery. In contrast, self-hosted HLS delivery needs enough outgoing capacity for your audience.
CPU, RAM and GPU Requirements
Use these rough starting points, then test your actual software:
| Workload | CPU | RAM | Additional needs |
|---|---|---|---|
| Single stream relay | 4 cores | 8 GB | Stable network |
| Multiple relays and packaging | 8 cores | 16 GB | Fast SSD |
| Several live transcodes | 12–16+ cores | 32 GB+ | Suitable GPU encoder |
These are planning estimates, not guaranteed capacities. Software encoding uses substantial CPU time, especially at high resolution. A compatible GPU with hardware encoding can reduce CPU pressure. Always benchmark the number of simultaneous outputs you need.
How Much Streaming Bandwidth Do You Need?
For self-hosted delivery, multiply average bitrate by simultaneous viewers. For example:
200 viewers × 6 Mbps = 1,200 Mbps, or 1.2 Gbps before audio, protocol overhead and safety margin.
A 1Gbps port would not support that example at full quality. A 10Gbps port provides more headroom, although it does not guarantee sustained internet throughput.
Bitrate varies with codec, frame rate and quality. Review YouTube’s live encoder bitrate guidance as a reference for source encoding settings. Your actual viewer-delivery bitrate may differ.
Storage, Streaming Software and Reliability
Choose SSD or NVMe storage for live segments, logs and temporary files. If you record broadcasts, estimate disk space separately. An encoded 6Mbps stream uses roughly 2.7 GB per hour, before overhead.
Streaming stacks may use RTMPS or SRT for ingest and HLS for playback. Test transcoding, latency and client compatibility before launch. Add monitoring for dropped frames, network saturation, disk usage and failed ingest connections.
Also protect stream keys, enable HTTPS where appropriate and restrict management access. A CDN can distribute audience traffic across regions instead of forcing every viewer through one server.
Choosing a 1Gbps or 10Gbps Dedicated Server
Start with viewer concurrency and measured peak traffic. Then check whether your provider offers a dedicated port, committed capacity, unmetered transfer and DDoS protection. Unmetered does not mean unlimited speed.
CybroHost 10Gbps dedicated servers include selected Bulgaria configurations with 1–10Gbps network options. Confirm the configured rate and upstream terms before ordering.
FAQs
Is 1Gbps enough for live streaming?
Often, for a modest audience or a single upstream relay. Calculate peak viewer traffic first.
Do I need a GPU for streaming?
Not for simple relaying. Multiple real-time transcodes may benefit from a compatible hardware encoder.
Does 10Gbps eliminate buffering?
No. Ingest stability, encoding, routing, storage and viewer connections also matter.
Final Recommendation
Choose hardware based on relay versus transcoding, then size bandwidth for peak viewers. Benchmark the full workflow and leave network headroom before going live.
