RX 7800 XT AV1 Encoding: Benchmark & Real-World Test 2026

Quick Answer

The RX 7800 XT's AV1 hardware encoder delivers excellent quality at significantly lower bitrates than H.264, making it a strong pick for streaming and YouTube uploads in 2026. In real-world tests it matches NVENC AV1 closely for streaming use cases while offering better value for SA buyers at current ZAR pricing.

How AV1 Encoding Works on the RX 7800 XT

RDNA 3's dedicated AV1 encoder block sits separate from the shader cores, meaning you can encode in AV1 without sacrificing in-game frame rates. At a 6Mbps stream bitrate, AV1 from the 7800 XT looks noticeably cleaner than H.264 at 8Mbps, especially in high-motion scenes like Apex or Warzone gunfights. YouTube and Twitch both support AV1 ingest now, so you finally get to use the full quality benefit without re-encoding to H.264 server-side. That matters even more on SA fibre lines where shaving 2Mbps off your stream bitrate frees up bandwidth for the rest of the household.

Real-World Benchmarks and OBS Settings

In OBS Studio with AMF AV1 encoder, CQP 22, and 1440p 60fps capture, the 7800 XT held steady frame times in Cyberpunk and Helldivers 2 with no measurable game performance hit. File sizes for 10-minute recordings dropped roughly 35-45% compared to H.264 at equivalent visual quality. For varsity LAN content creators editing in DaVinci Resolve afterward, the smaller files mean faster transfers between your laptop at res and your edit rig at home.

How It Compares to NVIDIA's AV1

NVENC AV1 on the RTX 4070 produces slightly cleaner low-bitrate output, but the gap is small enough that most viewers won't notice. The 7800 XT's edge is ZAR pricing, typically R2,000 to R3,500 cheaper than equivalent RTX 40-series cards in SA. For a streamer or content creator on a budget, that gap funds a decent USB mic and webcam upgrade.

Frequently Asked Questions

Does Twitch support AV1 ingest yet?

Yes, Twitch rolled out AV1 ingest in 2025 for enhanced broadcasting. You'll need a recent OBS build and AV1-capable GPU like the 7800 XT.

Can I record gameplay in AV1 and edit in DaVinci Resolve?

Yes, DaVinci Resolve 19 and later handle AV1 decode natively, especially smooth on systems with hardware AV1 decode like RDNA 3 or RTX 40-series.

Is AV1 worth it for YouTube uploads?

Definitely. AV1 source uploads to YouTube preserve more quality through the platform's re-encoding pipeline, giving viewers a cleaner final stream.
