Streaming PC Build Calculator

Recommend hardware specs for streaming at your target quality.

About this calculator

This calculator works from a simple hardware-planning principle: figure out which component actually does the heavy lifting for your setup, then size that component appropriately rather than over-speccing everything uniformly. The biggest factor in CPU core recommendations is your encoder choice — a CPU-based encoder (x264) does the video compression work on the processor itself, so it needs meaningfully more cores at higher resolutions or frame rates, while a GPU-based encoder (NVENC) offloads that work to dedicated hardware on the graphics card, letting the CPU stay comparatively modest and only scale up for whether you're also running a demanding game alongside the encode. GPU VRAM and RAM recommendations scale mainly with resolution, since higher-resolution capture and encoding buffers require more video memory and system memory regardless of which component handles the encoding itself, with game streaming adding its own baseline RAM requirement since a modern game plus a streaming application running simultaneously both need headroom.

Recommended upload speed is the one output driven purely by resolution — a 4K stream simply requires more outbound bandwidth than 1080p regardless of your hardware choices, since that's a network constraint independent of what's happening inside the PC. The estimated budget sums rough per-tier costs for CPU, GPU, and RAM plus a flat $300 placeholder for motherboard, power supply, case, and storage, so treat it as a ballpark for comparing setups rather than a real parts-list quote, since actual component prices shift constantly and this doesn't price specific SKUs.

How to Use This Calculator
  1. Set the target streaming resolution (720p, 1080p, 1440p, or 4K) and frame rate.
  2. Indicate whether you'll be streaming while gaming or doing camera/presentation only.
  3. Choose your encoder type: CPU (x264) for better quality, or GPU (NVENC) to offload encoding.
  4. Review the recommended RAM Needed, CPU Cores, and GPU VRAM for your settings.
  5. Check Upload Speed for your connection requirements and Est. Budget for a rough hardware cost.

What each input means

Stream Resolution
Target streaming resolution, which drives the recommended hardware specs.
Frame Rate
Target stream frame rate (30 or 60 fps).
Game Streaming (0=No, 1=Yes)
0 = camera/presentation only, 1 = streaming while gaming.
Encoder (0=CPU, 1=GPU)
0 = CPU encoding (x264, better quality), 1 = GPU encoding (NVENC, less CPU load).

Frequently Asked Questions

Why does choosing a GPU encoder reduce the recommended CPU cores so much?

GPU-based encoding (NVENC) offloads the video compression work to dedicated hardware built into the graphics card, so the CPU is freed up to focus mainly on running the game or application being captured rather than also compressing video in real time. A CPU-based encoder (x264) does that compression work on the processor itself, which is why it demands substantially more CPU cores, especially at higher resolutions or frame rates.

Does frame rate affect anything besides CPU cores in this calculator?

Frame rate only changes the CPU core recommendation, and only in the specific case where you've chosen CPU-based encoding at a lower resolution — RAM, GPU VRAM, and upload speed recommendations here are driven entirely by resolution and whether you're gaming while streaming, not frame rate. A 30fps and 60fps stream at the same resolution and encoder setting get identical RAM, VRAM, and bandwidth recommendations.

Is the estimated budget an actual parts list I can shop from?

No — it's a rough ballpark built from broad price tiers for CPU, GPU, and RAM based on the recommended specs, plus a flat placeholder for motherboard, power supply, case, and storage. Real component prices vary by brand, availability, and market conditions, so use this figure to compare the relative cost of different streaming setups rather than as a literal shopping budget.

Why does upload speed only depend on resolution and nothing else?

Upload bandwidth is a network requirement determined by how much video data you're pushing to the streaming platform per second, which scales with resolution (and implicitly the bitrate that resolution typically demands) regardless of what hardware inside your PC produced that video. Your encoder choice or CPU setup changes how efficiently the video gets compressed, but the final data rate leaving your connection is still governed mainly by the resolution you're streaming at.
