Live video is exploding, power budgets are shrinking, and the old “throw more GPU at it” mindset is breaking. We dig into the real constraint behind streaming at scale - energy - and share new data showing how VPUs can deliver 4–6x better efficiency than top-tier GPUs while holding quality where viewers notice it most. From the early days of CPU-only encoding to a modern, hybrid stack, we walk through the architecture that lets us stream more for less power without cutting corners on quality.
We break down head-to-head tests run in the cloud comparing an RTX 4080 (NVENC and CUDA) with a NETINT Quadra T1U across AV1, HEVC, and H.264. You’ll hear how watts per stream changes the math for ABR ladders, why low-resolution rungs dominate real-world viewing, and where GPUs still win - premium HD and UHD tiers, complex filters, and specialized compute. Then we zoom out to the big picture: if live traffic is already the majority of internet bandwidth and is set to triple by 2030, scaling responsibly means optimizing for both density and sustainability. The numbers at 1,000 concurrent streams are stark: roughly 22.6 kW on a GPU path versus around 5 kW on a VPU path, with similar throughput and better low-res quality in many cases.
Our takeaway is a simple, pragmatic strategy. Use GPUs where their strengths shine and use VPUs for the heavy lifting across low and mid ABR rungs. That hybrid approach cuts operational cost, reduces carbon impact, and increases resilience under peak load. Along the way, we share how our live control, encoder, origin, and editor fit together across on‑prem and cloud, and why energy-aware orchestration is now a core feature, not an afterthought.
