If you're running OBS on a remote Windows server to stream 24/7, the real technical decision isn't between made-up categories like "streaming RDP" and "encoding RDP" - it's a genuine, well-documented choice every OBS user faces: NVENC (hardware encoding on the GPU) versus x264 (software encoding on the CPU).[1][4] Here's what actually separates them and which one to pick.
NVENC: Hardware Encoding
NVENC is NVIDIA's dedicated hardware video encoder, built directly into the GPU. Because it's a separate chip from the one running your game or application, it uses almost none of your CPU or GPU rendering capacity - the encoding happens essentially "for free" alongside everything else the machine is doing.[6] Recent GPUs (RTX 40/50 series) include multiple encoder chips, letting you encode multiple simultaneous outputs - useful if you're streaming to more than one platform at once.[1]
- Best for: 24/7 unattended streaming, multi-platform simulcasting, machines also running the actual game or application being streamed.
- Trade-off: historically slightly lower quality per bitrate than x264 at identical settings, though the gap has narrowed significantly on recent NVENC generations.[9]
x264: Software Encoding
x264 encodes using the CPU instead of dedicated hardware. At the same bitrate, a well-tuned x264 preset can produce noticeably better image quality than NVENC, particularly in high-motion scenes - this is a real, measurable difference, not just fan preference.[9][10] The cost is CPU load: x264 competes directly with whatever else the CPU is doing, which matters if the same machine is also running the application being streamed.
- Best for: machines with CPU headroom to spare, situations where visual quality at a capped bitrate matters more than encoder overhead.
- Trade-off: a slower preset (better quality) demands more CPU; pushed too far, it causes dropped frames instead of encoding ones.
NVENC vs x264 at a Glance
| Factor | NVENC | x264 |
|---|---|---|
| Runs on | GPU (dedicated chip) | CPU |
| Resource cost | Minimal CPU/GPU render impact | Competes with CPU load |
| Quality per bitrate | Very good, improving each GPU generation | Slightly better at matched settings[9] |
| Multi-stream support | Multiple encoder chips on newer GPUs[1] | Limited by total CPU capacity |
| Recommended for | 24/7 unattended, multi-platform, GPU-heavy workloads | Spare CPU capacity, single-destination quality-first streams |
Twitch and YouTube's Own Recommendations
Twitch officially recommends CBR (constant bitrate) rate control and supports both x264 and NVENC, with specific bitrate targets per resolution: roughly 6,000 kbps for 1080p60, 4,500 kbps for 1080p30/720p60, and 3,000 kbps for 720p30.[2][10] Twitch's general guidance is to keep bitrate at 50-75% of your available upload speed to leave headroom for stability.[10] YouTube Live supports higher bitrates and additional codecs (HEVC, AV1 on RTX 40-series+), useful if you're targeting higher resolutions.[1][8]
Why Run This on a Remote Server at All?
Streaming 24/7 from a home PC means your stream goes down the moment your PC sleeps, your ISP drops, or the power blinks - all common, all avoidable. A dedicated remote server built for this keeps OBS and your stream running independent of your own hardware and connection, with a GPU sized specifically for NVENC encoding rather than shared with whatever else the machine happens to be doing.

FAQ
Is NVENC "cheating" compared to x264?
No - it's a legitimate, purpose-built hardware encoder that both NVIDIA and Twitch officially support and recommend.[1][2] The quality gap versus x264 has narrowed with each GPU generation.
Which encoder does Twitch recommend?
Twitch supports both and doesn't mandate one - it recommends CBR rate control and provides bitrate targets per resolution/framerate regardless of which encoder you choose.[2][10]
Can I run OBS on a remote server without a dedicated GPU?
You can, but you'll be limited to x264 software encoding, which will compete with whatever else that CPU is doing - fine for light workloads, a bottleneck for anything demanding.
What bitrate should I actually use?
Follow the platform's own numbers: roughly 4,500-6,000 kbps for 1080p on Twitch, higher on YouTube if your upload speed supports it, and never above about 75% of your total available upload bandwidth.[2][10]
Do I need to pick the closest streaming ingest server too?
Yes - ingest server distance affects upload latency and stability independently of your encoder choice; Twitch provides a recommended-ingest tool for this.[15]
Does this apply to recording, not just live streaming?
Yes, the same NVENC-vs-x264 trade-off applies to local recording in OBS - NVENC again wins on resource usage, x264 on raw quality per file size at matched settings.
