The NVIDIA GeForce RTX 4070 is the sweet spot for content creators in 2026. It features the same 8th generation NVENC encoder as the RTX 4080 and 4090, providing flagship-level encoding quality at a mid-high price point.
With 12GB VRAM and dual encoder capability, the RTX 4070 can handle 1440p streaming while gaming, or even multi-encode setups (streaming to two platforms simultaneously). The hardware AV1 encoding is particularly valuable for YouTube creators who want maximum quality.
The P5 preset is ideal for the RTX 4070. It provides excellent quality with minimal performance impact, and the extra headroom compared to the RTX 4060 means you won't see any stuttering even in demanding games.
Common Issues with RTX 4070 Streaming
- 12GB VRAM Limitation: While generous for most scenarios, 4K gaming + streaming may push memory limits. Stick to 1440p streaming for best results.
- Not Ideal for 4K Streaming: For 4K streaming, consider the RTX 4080 or 4090 for better headroom.
Frequently Asked Questions
Is RTX 4070 good for streaming?
Excellent. The RTX 4070 is one of the best value GPUs for streaming in 2026, with 8th gen NVENC, AV1 support, and dual encoder capability.
Should I use AV1 or H.264 with RTX 4070?
Use AV1 for YouTube for better quality at lower bitrates. Use H.264 for Twitch until their AV1 support is fully available.
What bitrate for RTX 4070 1440p streaming?
For 1440p 60fps streaming, use 8000-9000 Kbps on YouTube. For Twitch, you're limited to 6000 Kbps, so consider 1080p for better quality.
