When you stream or record gameplay from a laptop, the encoder you choose decides how good your video looks at a given bitrate and how much performance it steals from your game. Modern gaming laptop GPUs include dedicated encoding hardware that can use several codecs, and the newest, AV1, promises meaningfully better quality than the long-standing H.264 workhorse. Here is how they compare in practice.
Hardware encoders explained
A hardware encoder is a dedicated block on the GPU that compresses video without loading the main graphics cores much. This is why streaming from a gaming laptop barely dents frame rates when you use the GPU encoder instead of the CPU. The two codecs that matter today are H.264, which every platform supports, and AV1, a newer codec that packs the same quality into a smaller bitstream.
Why bitrate is the whole game
Streaming platforms cap your upload bitrate, often around 6,000-8,000 kbps for non-partnered streamers. At those limits, fast-moving 1080p or 1440p gameplay looks blocky with older codecs because there simply are not enough bits to describe all the motion. A more efficient codec produces cleaner video at the same bitrate, which is exactly where AV1 shines.
| Codec | Relative efficiency | Quality at 6 Mbps | Platform support |
|---|---|---|---|
| H.264 (NVENC) | Baseline | Softer, some blocking in motion | Universal |
| HEVC/H.265 | ~30-40% better | Cleaner, limited live support | Recording, some platforms |
| AV1 | ~40-50% better | Noticeably sharper motion | Growing, newer GPUs |
When AV1 is the clear winner
If your laptop GPU has an AV1 encoder and your streaming platform accepts AV1 ingest, it is the better choice for bitrate-limited streaming; the same 6 Mbps looks visibly cleaner, especially in grass, smoke, and fast camera pans. For local recording where you can use a high bitrate, the codec matters less because there are plenty of bits to go around, though AV1 still saves storage space.
When H.264 still makes sense
H.264 via NVENC remains the safe, universal option. Every platform, player, and editing tool accepts it, and older laptop GPUs only offer H.264. If your audience or platform cannot decode AV1, or your GPU predates AV1 encoding, H.264 at the highest bitrate you are allowed is perfectly good. Compatibility beats efficiency when your viewers cannot play the stream.
Practical encoder settings
Whichever codec you use, prefer the GPU hardware encoder over CPU x264 to keep frame rates high while gaming. Set the encoder preset toward quality if your GPU has headroom, keep your bitrate at the platform maximum, and match resolution and frame rate to what you can sustain, commonly 1080p60 or 1440p60. Test a short recording and inspect motion-heavy scenes to confirm the result.
Recording versus streaming
The codec calculus changes depending on whether you are streaming live or recording locally. Streaming is bitrate-constrained by the platform and your upload, which is exactly where AV1’s efficiency pays off, delivering cleaner motion at the same capped bitrate. Local recording has no such limit; you can set a generous bitrate that makes even H.264 look excellent, so the visual gap between codecs narrows. There, AV1’s main benefit is smaller file sizes for the same quality, which adds up if you record hours of footage.
Editing workflow is the catch with recording in newer codecs. Some editing software and older machines struggle to scrub AV1 or HEVC footage smoothly, forcing you to transcode to a friendlier format before editing. If your editor handles the codec well, recording in AV1 saves storage; if it stutters, record in H.264 or a dedicated editing codec for a smoother timeline. Match the codec to the destination: efficiency for the bitrate-limited live stream, and editability for footage you plan to cut together afterward.
FAQ
Does AV1 encoding hurt my in-game frame rate more than H.264?
Not meaningfully. Both run on the dedicated encoder block, so the impact on your game is small either way. The difference is in output quality per bitrate, not in gaming performance.
Can I record in AV1 and upload to any platform?
You can record in AV1 to save space, but some platforms and older devices still cannot play AV1 smoothly. For maximum compatibility, either export a copy in H.264 or confirm your destination supports AV1 playback.
Bottom line
For bitrate-limited live streaming, AV1 on a supported laptop GPU delivers clearly better image quality than H.264 NVENC at the same upload cap, with no extra hit to your game. Use AV1 when your hardware and platform support it, fall back to H.264 for universal compatibility, and always run the GPU encoder rather than the CPU to protect your frame rate.
