Bitrate & Codec Comparison
Benchmark two video encoding setups side-by-side. Compare H.264 vs HEVC vs AV1, 1080p vs 1440p, and measure instant bandwidth delta % and Bits Per Pixel (BPP) quality density.

Generational Codec Compression Matrix
Comparative efficiency, royalty status, and hardware encoder compatibility:
| Codec / Generation | Compression Efficiency | Equivalent 1080p60 Bitrate | Hardware Encoding | Licensing / Royalties |
|---|---|---|---|---|
| H.264 / AVC (MPEG-4 Part 10) | 1.0x (Baseline Reference) | 6,000 kbps | Universal (All modern hardware) | Royalty-bearing (MPEG LA) |
| VP9 (Google Open Codec) | ~1.35x (+35% more efficient) | 4,400 kbps | Intel QuickSync / AMD AMF | Royalty-Free (Open Source) |
| H.265 / HEVC (MPEG-H Part 2) | ~1.50x (+50% more efficient) | 4,000 kbps | NVIDIA GTX 900+ / RTX, Apple Silicon | Complex Patent Pools (HEVC Advance) |
| AV1 (AOMedia Video 1) | ~1.80x (+80% more efficient) | 3,300 kbps | RTX 40-Series, Intel Arc, Radeon 7000 | Royalty-Free (AOMedia Alliance) |
How to Interpret Bits Per Pixel (BPP)
- <0.05 BPP: Heavy compression artifacts; grass, foliage, and fast-motion camera pans will pixelate.
- 0.05 – 0.08 BPP: Standard broadcast target for live streaming (Twitch, Kick). Clean during normal motion.
- 0.08 – 0.12 BPP: Crisp, high-fidelity capture suitable for YouTube archival uploads.
- >0.12 BPP: Ultra-high archival grade; diminishing returns for human visual perception.
Hardware Acceleration in OBS Studio 30+
Modern GPU hardware encoders (NVIDIA NVENC, AMD AMF, Intel QuickSync) offload 100% of video compression from the CPU with zero gaming performance penalty. With AV1 hardware encoding now supported on Twitch Enhanced Broadcasting and YouTube Live, streamers can broadcast at 1440p while consuming 40% less bandwidth than 1080p H.264.
Frequently Asked Questions: Bitrate Comparison
How much bandwidth does AV1 actually save compared to H.264?
AV1 offers approximately 40% to 50% greater compression efficiency compared to H.264 (AVC). This means an AV1 stream encoded at 3,500 kbps delivers equivalent or superior visual clarity (VMAF score) to an H.264 stream encoded at 6,000 kbps, drastically reducing internet upload requirements.
What is Bits Per Pixel (BPP) and why is it important?
Bits Per Pixel (BPP) = Bitrate in bps / (Width × Height × FPS). It measures how many bits of data the encoder allocates to each individual pixel on screen per second. For 1080p60 H.264, a BPP of 0.05 to 0.08 represents standard streaming quality, while 0.10+ represents pristine local recording quality.
Why is 900p60 sometimes better than 1080p60 at the same 6,000 kbps bitrate?
900p (1600x900) contains 31% fewer pixels per frame than 1080p (1920x1080). At a constrained 6,000 kbps bitrate on Twitch, 900p delivers a BPP of 0.069 compared to only 0.048 for 1080p. In fast-paced games (Apex Legends, Warzone, Overwatch), this extra bit density eliminates pixelated macroblocking and grass blur.
Which graphics cards support hardware AV1 encoding?
Hardware AV1 encoding requires modern GPUs: NVIDIA GeForce RTX 40-Series or newer (NVENC Dual 8th Gen), Intel Arc Alchemist/Battlemage (QuickSync), AMD Radeon RX 7000-Series or newer (VCN 4.0), or Apple Silicon M3/M4 chips. Older GPUs can decode AV1 in hardware but must fall back to CPU software encoding (libsvtav1) for export.
