Hardware-Accelerated Encoding
OBS supports GPU-based encoders like NVIDIA NVENC or AMD VCE, which offload video encoding from the CPU to the GPU.

Ranking | GPU Models | Core Advantages | Recommendation |
---|---|---|---|
1️⃣ | RTX 4090 | Strongest hardware encoding, multi-streaming capability, AV1 support | ⭐⭐⭐⭐⭐Professional level |
2️⃣ | RTX 3060 ti / 2060 | High bitrate support, suitable for 4K/HDR streaming | ⭐⭐⭐⭐ High-end |
3️⃣ | GTX 1650 / 1660 | has NVENC, new architecture (Turing) | ⭐⭐⭐ Medium budget |
4️⃣ | P620 / P1000 / T1000 | has NVENC, but it is older | ⭐⭐ Useful for beginners |
Problems | Description |
---|---|
High resource usage | OBS video encoding + game running + scene special effects processing will seriously occupy the CPU and GPU, resulting in lag or frame drops. |
Insufficient bandwidth | Home network upload bandwidth is usually only 10~50 Mbps, which cannot support high bit rate and multi-platform streaming, and is prone to lag or interruption. |
Instability | Power outages, network transmission, system crashes, etc. may interrupt live broadcasts. |
Aging equipment or insufficient performance | Old computers or low-end devices will lag when processing high-definition video encoding. |
Difficult to manage remotely | Unable to or exclude restrictions on physical environment for operation, monitoring and recovery, and flexibility. |
Not suitable for adult channel live broadcast | Local machines are generally only suitable for one person, and do not support multi-person collaboration or multiple channels at the same time. |
Heat and noise | Under high load, the hardware will heat up and the fan noise will be loud, affecting the environmental experience. |
Poor expansion capability | Hardware upgrades are troublesome and costly, and cannot be horizontally expanded as flexibly as servers. |
Advantages | Description |
---|---|
Powerful performance, optimized for encoding | GPU servers are equipped with professional graphics cards (such as RTX/A series), and can use NVENC encoding, which greatly reduces the CPU burden. |
High upload bandwidth | The data center provides external export bandwidth of 100Mbps, 1Gbps, and even more than 10Gbps, making live broadcasts smoother. |
Stable and reliable | The server is deployed in a professional computer room and is equipped with UPS power supply, network printer, hard disk RAID and other stable mechanisms. |
Remote management and support automation | Remote control, scheduled streaming, content switching, etc. can be achieved through RDP, SSH or OBS WebSocket scripts. |
Support multi-platform simultaneous streaming | On a server, OBS automatically sends to Twitch/YouTube/Bilibili at the same time, consuming additional transit platforms. |
Flexible expansion and separation | Multiple accounts can use different OBS instances, supporting virtual anchors, brand numbers, and program numbers to run separately. |
Support advanced features such as virtual people and cloud games | Can host Unreal/Unity and Live2D models, suitable for cutting-edge scenarios such as VTuber, AI anchors, and cloud games. |
More professional live broadcast quality and stability | Can run FFmpeg/OBS plug-ins to achieve higher bitrates and higher levels of color management (such as HDR, 10bit). |
Usage scenario | Local Computer Streaming | GPU Server Streaming |
---|---|---|
Ordinary personal live broadcast (single platform) | ✅ Available, but set to bandwidth/performance | ✅ Excessive, unless it is a high bit rate |
Virtual anchor (Live2D/3D) | ❌ CPU/GPU heavy load, low frame rate | ✅ Can run and push streams beyond the limit |
Multi-platform simultaneous live broadcast | ❌ Local bit rate/bandwidth is limited | ✅ Encode once, forward on multiple platforms |
Game live broadcast + AI automatic commentary | ❌ Unable to handle multiple loads in real time | ✅ Running OBS + AI model without pressure |
24-hour live broadcast channel | ❌ Power and stability cannot be guaranteed | ✅ Professional server runs stably |
